Subwoofer enheder

SUB-8 er en subwoofer fra Earthquake med kun 92mm dybde Denne subwoofer til indbygningslyd vedholde det samme udseende som en almindelig 8" indbygningshøjttaler som VQ8, ECS-8.0 eller SPE-82HQ Men kun 92mm i dybden giver den mulighed for at få noget dyb i loftet til trods for at pladsen er trang. Det er opnået ved at konstruktionen har selve motorsystemet bygget på forsiden af enden. Den har indbygget delefilter så den kan fødes med et fullrange forstærker signal, hvor et scenarie kunne være at forbinde på samme forstærker udgang sammen med en af de overstående højttalere og dermed ialt ha en 4 ohms belastning. Har du allerede 2 indbygnings højttalere på 8 ohm hver på en forstærker udgang er det højest sandsynligt for stor en belastning med at koble denne her til oven i dem da det vil give for lav impedans. Med ekstra lang slaglængde for den bevæget noget mere luft end en almindelig indbygningshøjttaler Det er en hjælp til bedre performance med en kasse bag den på ca 25 liter og der er en tegning i billederne. Til denne type enhed anbefaler vi en halv pakke MDM-2 dæmpeuld i kassen, og hvor det er trukket ud så det er løst som candyfloss.

Nyd Højkvalitets Lyd med Earthquake Sound's Pro-X15-8 Subwoofer Introducer Pro-X15-8, den professionelle subwoofer fra Earthquakesound der tilbyder høj ydeevne og fremragende værdi. Med 30 års erfaring i fremstilling af topklasse woofere, er Pro-X-linjen bygget med den højeste kvalitet og ekspertise. Pro-X15-8 subwooferen er designet til at fylde den tomme mellem dyre, højtydende subwoofere og billige, lavkvalitetsmuligheder på pro woofer-markedet. Med sin næsten enterprise-niveau ydeevne er Pro-X15-8 den perfekte løsning for dem, der ønsker høj kvalitet lyd til en overkommelig pris. Typisk, når man designer et statement-produkt, er det en øvelse i brugen af eksotiske materialer og total mangel på hensyn til omkostninger for at infuse eksklusivitet i produktet. Med Pro-X var målet det stik modsatte - at fjerne alt det ikke-essentielle og udgrave den rene essens af ydeevnen. Under denne proces udviklede vi flere teknologier og designattributter, der ville blive essentielle for det endelige produkt. PWT Voice Coil (Svingspole med parallelt spoleteknologi) PWT (Parallel Winding Technology) svingspolen er en ganske enkel, men effektiv metode til at nærme sig esoteriske kant-spolerede svingspoler i effektivitet og termisk holdbarhed. Almindelige svingspoler er spundet med en enkelt tråd, der anvendes på formen x antal omgange. PWT-spolen bruger to tyndere tråde, der anvendes parallelt på formen (spundet side om side) x antal omgange. Dette øger signifikant overfladearealet for forbedret termisk stivhed, mens impedansen er den samme som ved brug af almindelig enkelt-trådstrømpe. Til en brøkdel af omkostningerne ved kant-spolerede svingspoler, er PWT svingspolen afgørende for at holde prisen nede og ydeevnen høj. L-RAE Motor Cooling Geometry (L-RAE-kølingsgeometri for motoren)   Pro-X har den nye L-RAE (Large Radial Air Emitter) kølingsløsning og er det første produkt fra Earthquake, der gør dette. Vi havde til hensigt at bruge vores patenterede TCT (Turbine Cooled Technology); men TCT var udviklet til tunge, lange slag-højttalere og var ikke ideel for de hurtige, spændte og agile egenskaber hos Pro-X-højttaleren.   L-RAE består af store urestriktive passager med nul modstand for den bevægende luft. En stor boret ud stolpe med udluftningskanaler på siden af spindlen kombineres med overskårne radielle kølepassager, der matcher diameter af svingspolen.     Dette overfører effektivt luft omkring svingspolen og reducerer luftmodstanden på den bevægende svingspole selv. Resultatet er et bemærkelsesværdigt kapabelt kølesystem, der sammenlignet med en traditionel stolpeventilationsløsning reducerer temperaturer med 40 procent. Alt uden at tilføje akustiske artefakter eller omkostninger til ligningen.   Høj Gauss keramikmagnet   Den voldsomme magnetkraft i Pro-X leveres af en oversizeret keramikmagnet. Denne høje Gauss-magnet koncentrerer en immense magnetflade på svingspolen, hvilket resulterer i stjernespændende effektivitet og tæt bryststødende lavfrekvensrespons. Designet med en bumpe-tilbage-udvidet stolpe for øget bevægelsesmulighed. Dette beskytter også svingspolen mod at støde ned i tilfælde af transient overbelastning. Legendarisk Kabinet Enhver erfaren pro-audio handelsmand vil genkende kabinettet og smile. Ja, det er over 30 år gammelt, men set fra et ydelsesmæssigt synspunkt, er der endnu ikke blevet lavet en bedre. Alsidighed Selvom det er designet som en pro-audio woofer, kan det bruges med stor succes både i hjemmet og i bilapplikationer. Det kan bruges i ethvert tilfælde, hvor der er behov for store mængder af lav forvrængning, bredbåndslydenergi. Det er ideelt til brug i små lukkede og porterede kabinetter såvel som bas- og mellem-bas horn. Med en meget lav monteringsdybde kan Pro-X bruges i specielle formfaktor-systemer. Værdi Bygget fra grunden med de grundlæggende elementer, der gør et produkt typisk earthquake - Power, Performance og Quality. Pro-X tilbyder utrolig ydelse til en uovertruffen pris. Det er vores oprigtige overbevisning, at kombinationen af pris, ydelse og kvalitet gør Pro-X til det bedste i denne kategori på markedet i dag. Bevist Track Record I 30 år har earthquake designet og produceret topkvalitets lydudstyr. Pro-X er ingen undtagelse fra denne ledelse af excellence. Vi er sikre på, at de vil give mange års trofast service.

Introducing Pro-X Professional Subwoofers Pro-X is the line of high sensitivity wide-band professional woofers from Earthquake Sound. Built with the accumulative knowledge and expertise gained from manufacturing industry defining woofers for 30 years. Pro-X is proof positive that the combination of high performance and superior value is possible! For years its been our analysis that the pro woofer market has a huge split between performance and value. The leading brands build $1500+ starship woofers and an almost unending slough of no-name brands flood the market with cheap, but essentially worthless woofers. We offer Pro-X as the meaningful solution. Providing near enterprise level performance at less than a third of the cost. Typically when designing a statement product its an exercise in the use of exotic materials and blatant disregard for the cost as a way of infusing exclusivity into the product. With Pro-X the goal was just the opposite - chip away all non-essentials and unearth the raw essence of performance. During this process we developed several technologies and design attributes that would come to be essential for the final product. PWT Voice Coil The PWT (Parallel Winding Technology) voice coil is a quite simple but effective method for approaching esoteric edge-wound voice coils in efficiency and thermal durability. Ordinary voice coils are wound with a single wire applied to the former x number of turns. The PWT coil uses two thinner wires applied to the former in parallel (wound side by side) x number of turns. This significantly increases surface area for improved thermal rigidity while keeping the same impedance as if regular single strand wire had been used. At a fraction of the cost of edge-wound, the PWT voice coil is instrumental in keeping the price down and performance up. L-RAE Motor Cooling Geometry Pro-X features the L-RAE (Large Radial Air Emitter) cooling scheme, and is the first Earthquake product to do so. We had intended to use our patented TCT (Turbine Cooled Technology); however, TCT was developed for heavy, long stroke woofers and was not ideal for the quick, taunt and agile characteristics of the Pro-X woofer. L-RAE is comprised of large unrestricted passages offering zero resistance to the moving air. A large drilled out pole piece with above spider side venting channels is combined with oversized radial cooling passages, matching the diameter of the voice coil. This efficiently transports air around the voice coil and reduces the air resistance on the moving voice coil itself. The result is a remarkably capable cooling system that compared to a traditional pole venting scheme, reduces temperatures by 40 percent. All without adding acoustic artifacts or cost to the equation. High Gauss Ceramic Magnet The brute magnetic force in the Pro-X is supplied by an oversized ceramic magnet. This high Gauss magnet concentrates immense magnetic flux on the voice coil resulting in stellar efficiency and tight chest slamming low frequency response. Designed with a bumped back extended pole piece for added excursion potential. This also protects the voice coil from bottoming out in case of transient overload. Legendary Chassis Any seasoned pro audio tradesman will recognize the chassis and smile. Yes it is 30+ years old, but from a performance viewpoint - a better one has yet to be made. Versatility Although designed as a pro audio woofer, it can be used in both home and automotive solutions with great success. It can be used in any application where large amounts of low distortion, wide-band acoustical power is needed. It is ideal for use in small sealed and ported enclosures as well as bass and mid-bass horns. Featuring a very shallow mounting depth the Pro-X can be used in specialty form factor systems. Value Built from the ground up with the fundamental elements that makes a product distinctly Earthquake - Power, Performance and Quality. Pro-X offers amazing performance at an unparalleled price. It is our sincere belief that the combination of price, performance and quality makes the Pro-X the best in this category on the market today. Proven Track Record For 3 decades Earthquake has been designing and manufacturing top quality audio equipment. The Pro-X is no exception to this ledger of excellence. We are certain they will provide many years of faithful service. Sold and priced per piece.

Subzero -When only the best will do This latest iteration of Subzero is a tour de force of how advanced design and technology can come together to create superior sound quality. All aspects of the design have been perfected to the smallest detail, resulting in truly revolutionary woofer performance. Subzero is capable of an incredible 3" excursion (12" Subzero). With excursion of this magnitude, Subzero produces levels of bass unattainable by conventional woofers. The extreme excursion ability coupled with the unique suspension makes Subzero extremely transient proficient. Even a light touch on the cone, easily moves it several centimeters. This ease of movement combined with the ultra-powerful magnet system results in a spectacularly fast and precise response. Subzero is free of the mechanical and electrical constraints inherent to common woofers. Lava-fused Octo Helix voice coil Subzero is equipped with a unique voice coil of oversized proportions. All aspects of the voice coil design are optimized for maximum performance, durability and sound quality.In the creation of the Subzero voice coil, Earthquake scientists have boldly challenged the very genesis of the voice coil itself. Traditionally, a lot of effort goes into choosing the right voice coil former (the cylinder to which the coil is wound). The former must be light, have similar heat expansion properties to the voice coil and it must promote cooling. Constantly advancing the state of the art, Earthquake engineers theorized that the best solution must be to have no former at all. While this theory flies in the face of all conventional wisdom, our engineers pressed on. During this proof-of-concept phase, it was realized that the technology needed to do away with the former simply did not exist. Instead of abandoning the quest for formerless technology, the research was extended to include facilitating technologies. In place of the structural support provided by the former, a super strong ultra high temperature adhesive was needed. A new insulator for the coil wire was also needed as traditional lacquer insulator does not have sufficient bonding properties for it to fuse together at the required tensile strength. This challenge was constructive in its own right as the biggest threat to woofer survival is heat, if the essence of this new technology would bring forth a temperature resilient voice coil it would serve to improve all other aspects of woofer operation. The creation of the needed high temperature adhesive proved difficult and the next break would come as an unlikely discovery by our Chief engineer while on vacation in Hawaii. Taking a scenic tour of Hawaii, he was walking through an area with volcanic ash and realized that the ideal base substance for a high temperature adhesive would be a material with no combustible elements left. Volcanic ash fits this description perfectly as it has been exposed to extreme heat - it has been combusted to the point where further heat exposure will not change its molecular structure. The volcanic ash was taken to our German adhesive manufacturing partner and six months later we had our next generation temperature invariant super adhesive. Now we just needed an equally temperature resistant insulator. The only known insulator capable of withstanding this immense heat was anodizing. Anodizing however is problematic because it breaks off the host material if it is bent beyond a certain point. After much experimentation it was discovered that it is possible to prevent the anodizing from breaking off if the coil wire is heated to red hot temperature at the time of winding. Finally, the first former-less voice coil could be made. The audible qualities springing from this new lighter and stronger coil type is nothing less than remarkable. Signature technologies such as the Octo-Helix winding scheme has evolved for use in the new Subzero. The Octo-Helix design requires a very advanced production process. The Helix design is unique because it allows identical electromagnetic coupling and thermal signatures of two voice coils. In a conventional subwoofer with dual voice coils, they are wound one on top of the other, resulting in asymmetrical electromagnetic coupling and heat dissipation capability. The Helix structure is free of these limitations, since the two coils are wound synchronously in-phase. The Helix wound voice coil is characterized by several obvious advantages - perfect electromagnetic coupling, identical thermal signature, lower distortion, higher performance and durability. The voice coil is comprised of eight (octo) layers of edge wound oxygen-free copper wire. This special copper wire is of the flat-wire type. Flat-wire has a much greater surface area than conventional round wire and can thus dissipate considerably more heat it. Another advantage is the coil can be wound closer - increasing motor power. The coil assembly meets mil-std specifications for temperature resilience - specifications set by the U.S. Department of Defense for use in military equipment. This guarantees peak performance even during hard and continuous operation. TCT - Turbine Cooled Transducer Subzero is equipped with the patented TCT (Turbine Cooled Transducer) technology. TCT creates cooling airflow similar to a tornado around the voice coil. The tornado is created by air forced through cooling channels milled in a vortex structure. Traditional voice coil cooling is done by drilling out the pole piece and the woofer stroke then pushes air back and forth. This cooling scheme only has a linear increase as a function of woofer stroke. TCT is different. TCT creates an exponential increase in cooling capacity as a function of woofer stroke. This is achieved by harnessing the centrifugal forces in the mini tornado to increase surface area contact between the air and voice coil. TCT is so effective that the voice coil temperature is reduced 50% compared to the same woofer without TCT. This prevents heat derived compression and keeps the woofer at maximum efficiency.. The compression is a result of the increased electrical resistance of the voice coil - the higher the temperature, the higher the resistance. Since TCT's cooling capacity increases exponentially with excursion, heat is not allowed to build up. The harder you drive Subzero the more it cools itself. Poly-Ether draw SWE (Super Wide Edge) suspension For Subzero our unique SWE (Super Wide Edge) suspension design has been enhanced by the use of Poly-Ether draw material. Sporting an extreme curve height of 62 mm the stage has been set for incredible excursion. The manufacturing of this advanced suspension is a complex process spanning several stages. Poly-Ether draw is used primarily in military applications because of its high strength and flexibility. The sophisticated and costly processing requirements has so far limited its use outside the military. Thanks to the obsessive high-tech emphasis by Earthquake, the entire Poly-Ether draw manufacturing process can be done in-house. As part of the manufacturing process, the Poly-Ether material is thermally pressed and laminated giving it extreme strength and mobility. The suspension geometry is of the single-layer type and allows ultra long excursion without mechanical breakup. This results in woofer stroke potential in excess of 100 mm without deformation or increased mechanical resistance.This ensures perfect reproduction of even the most bass heavy soundtracks Parabolic deep dish woofer cone The Subzero cone is made of a proprietary non-pressed fiber reinforced cellulose pulp substance with extreme stiffness. The cone is then superimposed with a parabolic deep dish made of a strong space age polymer that obtains additional rigidity by its geometric shape. The cone does not flex or deform regardless of input power and frequency. Dual Super-Spider with composite center and symmetric stitched tinsel leads The Subzero spider is of the super spider type, which means the spider has the same diameter as the cone -this ensures the spider is not limiting excursion. The Subzero is equipped with a double super spider unit comprised of a Nomax /Romax hybrid material that has been epoxy coated for increased strength. The individual super spider units are arranged as identical opposites - canceling nonlinearities inherent to typical single or dual spider designs.The result is a clean sound - free from mechanical artifacts. For optimal performance the edge suspension and spider must have the same excursion potential, this is not possible with a traditional spider of limited diameter. Traditionally, the spider is glued to the voice coil, this results in heat transfer from the voice coil to the spider. This heat transfer effects the spiders compliance and can over time degrade the spider. The Subzero super spider is not glued the voice coil, but attached to a composite center ring that in turn is bonded to the voice coil. The special composite material is neither heat sensitive nor a thermal conductor. Thus the endurance and longevity of the Subzero is not affected regardless of drive level. The tinsel leads to the voice coil are sewn into the spider to ensure against collision with the cone during extreme excursion. This also extends the life of the tinsel leads, as they now bend more gently over a longer distance. The symmetrical design of the tinsel leads prevents an asymmetrical pull on the cone. The result is longer woofer life, and greater endurance. Double stacked Cobalt-Ceramic high gauss magnet system Subzero is built around a gigantic magnet system. It consists of two huge Cobalt-Ceramic magnets which have been hyper magnetised in-house by Earthquakes military grade Magnetiser. The two magnets have a total thickness of 6 cm, the top plate alone is 1 cm and the pole piece is 5 cm. With a total height of 12 cm - the voice coil is given unhindered travel space far beyond its mechanical limits. This ensures that not even the strongest transient may cause the device to run out of electromagnetic coupling. At the same time the high gap height contributes to voice coil cooling, as the immense mass of metal effectively absorbs heat. Diamond cut chassis with XLT geometry The Subzero is based on Earthquakes signature XLT chassis geometry. It is the optimal design for extreme excursion. The XLT chassis allows for extra length between the spider (center suspension) and the magnetic gap. It is designed to accommodate oversized spiders and voice coils. The Subzero chassis feature another advanced design detail unique to the Subzero. All other woofers have the chassis mounted on top of the magnet. The Subzero encases the magnet within the chassis and the chassis is mounted to the magnet from behind. This special design prevents the chassis from degrading the magnetic flux asserted on the voice coil. The oversized and rigid chassis is made of cast aluminum which is then diamond cut. This results in an ultra-rigid and robust chassis featuring stunning good looks. The chassis is further characterized by all components of the assembly being bolted together with stainless steel machine screws. This design is extremely rugged compared to ordinary assemblies where the chassis and magnet system is often glued and / or tabbed together. The technically superior design ensures exceptional durability, sound quality and pride of ownership. Pris er pr. stk.

The Earthquake “SWS” - Shallow Woofer System- Provides more sound from less space with less power than any other woofer technology. The core technology of the SWS was pioneered by Earthquake Sound's President Joseph Sahyoun and is now protected by multiple global patents.The “SWS” design moves the flexible suspension components(cone & spider) to the side allowingthe motor to be elevated. This reduces the mounting depth of the speaker while enhancing excursion capability. More excursion (woofer movement) equals more sound.Upgrading to SWS is both attractive and simple :1. Direct factory drop-in replacement.2. Greatly enhanced sound quality. Enjoy a rich full bodied sound with articulation and dynamics rivaling home hifi audiophile systems.3. Plays louder and cleaner than standard woofer - using less power.4.

Earthquake SWS-10X Bas The Earthquake “SWS” - Shallow Woofer System- Provides more sound from less space with less power than any other woofer technology. The core technology of the SWS was pioneered by Earthquake Sound's President Joseph Sahyoun and is now protected by multiple global patents.The “SWS” design moves the flexible suspension components(cone & spider) to the side allowingthe motor to be elevated. This reduces the mounting depth of the speaker while enhancing excursion capability. More excursion (woofer movement) equals more sound.Upgrading to SWS is both attractive and simple :1. Direct factory drop-in replacement.2. Greatly enhanced sound quality. Enjoy a rich full bodied sound with articulation and dynamics rivaling home hifi audiophile systems.3. Plays louder and cleaner than standard woofer - using less power.4.

Klik på linket her for at få et system forslag til Subzero 10. Man kunne forledes til at tro at den har sin styrke til hjemmebiograffen, men egentlig er det mere det musikalske.   Subzero -When only the best will do This latest iteration of Subzero is a tour de force of how advanced design and technology can come together to create superior sound quality. All aspects of the design have been perfected to the smallest detail, resulting in truly revolutionary woofer performance. Subzero is capable of an incredible 3" excursion (12" Subzero). With excursion of this magnitude, Subzero produces levels of bass unattainable by conventional woofers. The extreme excursion ability coupled with the unique suspension makes Subzero extremely transient proficient. Even a light touch on the cone, easily moves it several centimeters. This ease of movement combined with the ultra-powerful magnet system results in a spectacularly fast and precise response. Subzero is free of the mechanical and electrical constraints inherent to common woofers. Lava-fused Octo Helix voice coil Subzero is equipped with a unique voice coil of oversized proportions. All aspects of the voice coil design are optimized for maximum performance, durability and sound quality.In the creation of the Subzero voice coil, Earthquake scientists have boldly challenged the very genesis of the voice coil itself. Traditionally, a lot of effort goes into choosing the right voice coil former (the cylinder to which the coil is wound). The former must be light, have similar heat expansion properties to the voice coil and it must promote cooling. Constantly advancing the state of the art, Earthquake engineers theorized that the best solution must be to have no former at all. While this theory flies in the face of all conventional wisdom, our engineers pressed on. During this proof-of-concept phase, it was realized that the technology needed to do away with the former simply did not exist. Instead of abandoning the quest for formerless technology, the research was extended to include facilitating technologies. In place of the structural support provided by the former, a super strong ultra high temperature adhesive was needed. A new insulator for the coil wire was also needed as traditional lacquer insulator does not have sufficient bonding properties for it to fuse together at the required tensile strength. This challenge was constructive in its own right as the biggest threat to woofer survival is heat, if the essence of this new technology would bring forth a temperature resilient voice coil it would serve to improve all other aspects of woofer operation. The creation of the needed high temperature adhesive proved difficult and the next break would come as an unlikely discovery by our Chief engineer while on vacation in Hawaii. Taking a scenic tour of Hawaii, he was walking through an area with volcanic ash and realized that the ideal base substance for a high temperature adhesive would be a material with no combustible elements left. Volcanic ash fits this description perfectly as it has been exposed to extreme heat - it has been combusted to the point where further heat exposure will not change its molecular structure. The volcanic ash was taken to our German adhesive manufacturing partner and six months later we had our next generation temperature invariant super adhesive. Now we just needed an equally temperature resistant insulator. The only known insulator capable of withstanding this immense heat was anodizing. Anodizing however is problematic because it breaks off the host material if it is bent beyond a certain point. After much experimentation it was discovered that it is possible to prevent the anodizing from breaking off if the coil wire is heated to red hot temperature at the time of winding. Finally, the first former-less voice coil could be made. The audible qualities springing from this new lighter and stronger coil type is nothing less than remarkable. Signature technologies such as the Octo-Helix winding scheme has evolved for use in the new Subzero. The Octo-Helix design requires a very advanced production process. The Helix design is unique because it allows identical electromagnetic coupling and thermal signatures of two voice coils. In a conventional subwoofer with dual voice coils, they are wound one on top of the other, resulting in asymmetrical electromagnetic coupling and heat dissipation capability. The Helix structure is free of these limitations, since the two coils are wound synchronously in-phase. The Helix wound voice coil is characterized by several obvious advantages - perfect electromagnetic coupling, identical thermal signature, lower distortion, higher performance and durability. The voice coil is comprised of eight (octo) layers of edge wound oxygen-free copper wire. This special copper wire is of the flat-wire type. Flat-wire has a much greater surface area than conventional round wire and can thus dissipate considerably more heat it. Another advantage is the coil can be wound closer - increasing motor power. The coil assembly meets mil-std specifications for temperature resilience - specifications set by the U.S. Department of Defense for use in military equipment. This guarantees peak performance even during hard and continuous operation. TCT - Turbine Cooled Transducer Subzero is equipped with the patented TCT (Turbine Cooled Transducer) technology. TCT creates cooling airflow similar to a tornado around the voice coil. The tornado is created by air forced through cooling channels milled in a vortex structure. Traditional voice coil cooling is done by drilling out the pole piece and the woofer stroke then pushes air back and forth. This cooling scheme only has a linear increase as a function of woofer stroke. TCT is different. TCT creates an exponential increase in cooling capacity as a function of woofer stroke. This is achieved by harnessing the centrifugal forces in the mini tornado to increase surface area contact between the air and voice coil. TCT is so effective that the voice coil temperature is reduced 50% compared to the same woofer without TCT. This prevents heat derived compression and keeps the woofer at maximum efficiency.. The compression is a result of the increased electrical resistance of the voice coil - the higher the temperature, the higher the resistance. Since TCT's cooling capacity increases exponentially with excursion, heat is not allowed to build up. The harder you drive Subzero the more it cools itself. Poly-Ether draw SWE (Super Wide Edge) suspension For Subzero our unique SWE (Super Wide Edge) suspension design has been enhanced by the use of Poly-Ether draw material. Sporting an extreme curve height of 62 mm the stage has been set for incredible excursion. The manufacturing of this advanced suspension is a complex process spanning several stages. Poly-Ether draw is used primarily in military applications because of its high strength and flexibility. The sophisticated and costly processing requirements has so far limited its use outside the military. Thanks to the obsessive high-tech emphasis by Earthquake, the entire Poly-Ether draw manufacturing process can be done in-house. As part of the manufacturing process, the Poly-Ether material is thermally pressed and laminated giving it extreme strength and mobility. The suspension geometry is of the single-layer type and allows ultra long excursion without mechanical breakup. This results in woofer stroke potential in excess of 100 mm without deformation or increased mechanical resistance.This ensures perfect reproduction of even the most bass heavy soundtracks Parabolic deep dish woofer cone The Subzero cone is made of a proprietary non-pressed fiber reinforced cellulose pulp substance with extreme stiffness. The cone is then superimposed with a parabolic deep dish made of a strong space age polymer that obtains additional rigidity by its geometric shape. The cone does not flex or deform regardless of input power and frequency. Dual Super-Spider with composite center and symmetric stitched tinsel leads The Subzero spider is of the super spider type, which means the spider has the same diameter as the cone -this ensures the spider is not limiting excursion. The Subzero is equipped with a double super spider unit comprised of a Nomax /Romax hybrid material that has been epoxy coated for increased strength. The individual super spider units are arranged as identical opposites - canceling nonlinearities inherent to typical single or dual spider designs.The result is a clean sound - free from mechanical artifacts. For optimal performance the edge suspension and spider must have the same excursion potential, this is not possible with a traditional spider of limited diameter. Traditionally, the spider is glued to the voice coil, this results in heat transfer from the voice coil to the spider. This heat transfer effects the spiders compliance and can over time degrade the spider. The Subzero super spider is not glued the voice coil, but attached to a composite center ring that in turn is bonded to the voice coil. The special composite material is neither heat sensitive nor a thermal conductor. Thus the endurance and longevity of the Subzero is not affected regardless of drive level. The tinsel leads to the voice coil are sewn into the spider to ensure against collision with the cone during extreme excursion. This also extends the life of the tinsel leads, as they now bend more gently over a longer distance. The symmetrical design of the tinsel leads prevents an asymmetrical pull on the cone. The result is longer woofer life, and greater endurance. Double stacked Cobalt-Ceramic high gauss magnet system Subzero is built around a gigantic magnet system. It consists of two huge Cobalt-Ceramic magnets which have been hyper magnetised in-house by Earthquakes military grade Magnetiser. The two magnets have a total thickness of 6 cm, the top plate alone is 1 cm and the pole piece is 5 cm. With a total height of 12 cm - the voice coil is given unhindered travel space far beyond its mechanical limits. This ensures that not even the strongest transient may cause the device to run out of electromagnetic coupling. At the same time the high gap height contributes to voice coil cooling, as the immense mass of metal effectively absorbs heat. Diamond cut chassis with XLT geometry The Subzero is based on Earthquakes signature XLT chassis geometry. It is the optimal design for extreme excursion. The XLT chassis allows for extra length between the spider (center suspension) and the magnetic gap. It is designed to accommodate oversized spiders and voice coils. The Subzero chassis feature another advanced design detail unique to the Subzero. All other woofers have the chassis mounted on top of the magnet. The Subzero encases the magnet within the chassis and the chassis is mounted to the magnet from behind. This special design prevents the chassis from degrading the magnetic flux asserted on the voice coil. The oversized and rigid chassis is made of cast aluminum which is then diamond cut. This results in an ultra-rigid and robust chassis featuring stunning good looks. The chassis is further characterized by all components of the assembly being bolted together with stainless steel machine screws. This design is extremely rugged compared to ordinary assemblies where the chassis and magnet system is often glued and / or tabbed together. The technically superior design ensures exceptional durability, sound quality and pride of ownership.

DBXi – højtydende subwooferenheder med avanceret teknologi. DBXi er en showcase for anvendelse og adaptering af ekstremt avanceret teknologi. Earthquakes unikke DBXi enheder repræsenterer en ny kategori af basenheder. DBXi gør valget for den seriøse selvbygger enkelt. Det er nu ikke længere nødvendigt at beslutte om subwooferen skal gå dybt med høj SPL eller være hurtig, præcis og musikalsk. Innovativ teknologi og revolutionerende bearbejdningsproces er kendetegnet i DBXi’s konstruktion. De har muliggjort fremstillingen af en subwooferenhed der kan levere tordnende høj kælderdyb bas med hurtighed, præcision og detaljer.Udviklingen af DBXi Udviklingen af de nye DBXi subwoofer enheder begyndte med en dybdegående revision af samtlige elementer i subwoofer design. Konklusionen blev at en forfining af eksisterende teknologi ikke kunne overkomme de kendte begrænsninger. Ny teknologi var en nødvendighed for at kunne præstere knogleknusende lavfrekvent respons og samtidig gå op i det nedre mellemtone område. Mange fabrikanter er i stand til at lave tunge og langsomme enheder der begynder at snuble over sig selv allerede ved 65 – 70 Hz. Ligeledes er mange fabrikanter i stand til at fremstille forvoksede mellemtoner der er hurtige, men ikke er i stand til at gå dybere end 60 Hz. Et af de helt store designkrav til DBXi var en lineær frekvensrespons fra 20 – 250 Hz (15” DBXi). Det der adskiller fantastiske subwooferenheder fra middelmådige, er paradoksalt nok deres evne til at gengive de højere frekvenser. Især ved musikgengivelse er en hurtig og hårdtslående bas meget mere medrivende end en bas som føles tung og langsom. En bas skal slå musikkens rytme an, ikke komme efter den.Magnetsystem baseret på nuklear teknologi DBXi’s ultra kraftige magnetsystem er resultatet af et usædvanligt samarbejde med atomkraft industrien i Wisconsin. For at opnå den ønskede motorkraft var det nødvendigt at øge styrken markant i forhold til traditionelle magneter. Dette indledte et samarbejde med en fabrikant af plutonium fuel rods (radioaktiv brændstofs cylindre til atomkraftsværk) i Wisconsin. Denne fabrikant havde opfundet en særlig varmsmedning (hot forging) proces, der muliggjorde fremstillingen af motorens bagplade og centerdel ud af et stykke. Gennem et længere samarbejde lykkedes det at videreudvikle fuel rod forging teknologien for fremstilling af super gauss koncentrerede magnetsystemer. Den ultra høje magnetiske intensitet opnås ved at alle magnetens feltlinier nu kan overføre magnetisk flux tabsfrit, da hele magnetstrukturen er et stykke i stedet for af flere som traditionelt. Det giver en ekstremt effektiv og præcis motor. Højtydende svingspole med patenteret turbinekøling I hjertet af DBXi sidder en overdimensioneret ultra seriøs svingspole. Alle aspekter ved svingspolens konstruktion er optimeret for maksimal ydelse, holdbarhed og lydkvalitet. Svingspole formeren (den cylinder svingspolen vikles på) er fremstillet af aluminium bobbin og ikke pap, Kapton® eller glasfiber. Brugen af aluminium bobbin sikrer at der ikke opstår hotspots på svingspolen takket være aluminiums gode varmelednings evne. Brugen af aluminium bobbin forvandler dermed hele svingspolen til en stor køleprofil der sikrer en jævn spredning af varmen, hvilket øger belastbarheden betydeligt. Svingspolen er viklet af kobber firkanttråd, brugen af firkanttråd forøger svingspolens køleevne betydeligt. Firkanttråd har et større overfladeareal end almindelig rund tråd og kan derfor afsætte væsentlig mere varme. Firkanttråd har også den fordel at spolen kan vikles tættere, hvilket øger motorkraften.Enheden er udstyret med Earthquakes patenterede TCT (Turbine Cooled Transducer) teknologi. TCT skaber en tornado-lignende kølende luftstrøm omkring svingspolen, der øges i intensitet med slaglængden. Tornadoen skabes ved at luft tvinges igennem kølekanaler, der er fræset i en hvirvel struktur. Traditionel svingspole køling gøres ved at polstykket er udboret og enhedens vandring skubber luft frem og tilbage, køleeffekten har her kun en lineær stigning som funktion af enhedens vandring. TCT er anderledes. Earthquakes unikke TCT (Turbine Cooled Transducer) skaber en eksponentiel stigning i køleeffekt, som funktion af enhedens vandring. Dette opnås ved at udnytte centrifugale kræfter i den roterende luft. TCT er så effektivt at svingspolens temperatur er nedsat med 50 % i forhold til samme motor uden TCT. Når en subwooferenhed belastes og dens vandring øges stiger svingspolens temperatur, dette leder til kompression. Kompressionen er et resultat af den stigende elektriske modstand i svingspolen, jo højere temperatur jo højere modstand. Da TCT’s køleevne stiger eksponentielt med enhedens vandring undgås varmeafledt kompression.Specialdesignet membran og ophæng for enorm vandring En magnet i verdensklasse og overdimensioneret svingspole kommer kun til sin ret hvis enheden kan tåle at bevæge sig. Til DBXi blev der udviklet et særligt SWE (Super Wide Edge) kantophæng med en højde på 31 mm. Kantophænget er af enkeltlags (single layer) typen, der er termisk presset og lamineret for ekstrem styrke og mobilitet. Det tillader membranvandring på mere end 62 mm uden deformation eller øget vandringsmodstand. Det sikrer at selv de kraftigste impulser bliver gengivet med perfekt, hurtig og præcis transientrespons. DBXi membranen er fremstillet af et specielt poly-injectet materiale der opnår yderligere stivhed ved sin geometriske udformning. Membranen hverken flexer eller deformerer uanset inputstyrke og frekvens. DBXi spideren er af superspider typen, hvilket betyder at spideren har samme diameter som membranen. Det sikrer at spideren ikke er vandringsbegrænsende, som det er tilfældet ved de fleste andre fabrikanters konstruktioner. For at opnå optimal ydelse skal kantophænget og spideren have samme vandringspotentiale, dette er ikke muligt ved en traditionel spider af begrænset diameter. Litzetrådene til svingspolens strømforsyning er indsyet i spideren for at sikre imod kollidering med membranen. Indsyningen forlænger også litzetrådenes levetid, da de nu bevæger sig ens over en længere afstand.

Intet overflødigt er tilføjet og intet væsentligt er fjernet. Flere nøgle teknologier fra de dyrere Earthquake subwoofer serier er nedarvet i TremorX. Resultat er en subwoofer enhed uden sammenligning i sin klasse. Avanceret og rationel inhouse produktion af TremorX giver disse opsigtsvækkende egenskaber til en uhørt lav pris. TremorX er bevis på at lav pris og høj kvalitet kan sameksistere. Nøgtern gennemgang og funktions rationalisering frem for kvalitets reducering er nøgleord for TremorXs konstruktion. Med Avancerede Earthquake teknologier som TCT (Turbine Cooled Transducer), XLT chassis, Mill-Temp Aluminium svingspole, Dual Symmetrical stitched Power Leeds og WE (Wide Edge) kantophæng. Står TremorX ikke tilbage for noget. Solid kvalitet og raffineret teknisk konstruktion gør TremorX til en klart valg for den pris og performance orienterede selvbygger. Mill-Temp Aluminium svingspoleI hjertet af TremorX sidder en overdimensioneret svingspole. Alle aspekter ved svingspolens konstruktion er optimeret for maksimal ydelse, holdbarhed og lydkvalitet. Svingspole formeren (den cylinder svingspolen vikles på) er fremstillet af aluminium og ikke pap, Kapton® eller glasfiber. Brugen af aluminium sikrer at der ikke opstår hotspots på svingspolen takket være aluminiums gode varmelednings evne. Brugen af aluminium forvandler dermed hele svingspolen til en stor køleprofil der sikrer en jævn spredning af varmen, hvilket øger belastbarheden betydeligt. Svingspolen er viklet af kobbertråd, Svingspolens konstruktion lever op til mil-spec standarten for temperatur bestandighed. Dette garanterer at svingspolen yder optimalt selv ved hård og vedvarende drift TCT - Turbine Cooled Transducer TremorX er udstyret med Earthquakes patenterede TCT (Turbine Cooled Transducer) teknologi. TCT skaber en tornado-lignende kølende luftstrøm omkring svingspolen, der øges i intensitet med slaglængden. Tornadoen skabes ved at luft tvinges igennem kølekanaler, der er fræset i en hvirvel struktur. Traditionel svingspole køling gøres ved at polstykket er udboret og enhedens vandring skubber luft frem og tilbage, køleeffekten har her kun en lineær stigning som funktion af enhedens vandring. TCT er anderledes. Earthquakes unikke TCT (Turbine Cooled Transducer) skaber en eksponentiel stigning i køleeffekt, som funktion af enhedens vandring. Dette opnås ved at udnytte centrifugale kræfter i den roterende luft. TCT er så effektivt at svingspolens temperatur er nedsat med 50 % i forhold til samme motor uden TCT. Når en subwooferenhed belastes og dens vandring øges stiger svingspolens temperatur, dette leder til kompression. Kompressionen er et resultat af den stigende elektriske modstand i svingspolen, jo højere temperatur jo højere modstand. Da TCT’s køleevne stiger eksponentielt med enhedens vandring undgås varmeafledt kompression. WE –Wide Edge ophæng TremorXs særlige Wide Edge kantophæng muliggør enorm vandring uden deformation og øget modstand. Kantophænget er af enkeltlags (single layer) typen, der er termisk presset for ekstrem styrke og mobilitet. Det tillader membranvandring på mere end 35 mm uden deformation eller øget vandringsmodstand. Det sikrer at selv de kraftigste impulser bliver gengivet med perfekt, hurtig og præcis transientrespons. TX Blacktop membranTremorX membranen er fremstillet af et specielt poly-injectet materiale der opnår yderligere stivhed ved sin geometriske udformning. Membranen hverken flekser eller deformerer uanset inputstyrke og frekvens. Dual Symmetrical Stitched Tensile LeedsLitzetrådene til svingspolens strømforsyning er indsyet i spideren for at sikre imod kollidering med membranen. Indsyningen forlænger også litzetrådenes levetid, da de nu bevæger sig ens over en længere afstand. TremorXs har særlige symmetriske litzetråds indsyning så litzetrådenes compliance ikke påvirker enheden asymmetrisk. Dette optimerer enhedens respons og sikrer lang holdbarhed selv ved meget hård drift, da svingspolen bevæger sig helt lige i magnetgabet. XLT chassisTremorX er opbygget på Earthquakes XLT chassis struktur i støbt aluminium. Det er optimeret til TremorXs lange svingspole og kraftige magnet. Det er vigtigt at chassiset tillader tilstrækkelig længde mellem spider (center ophæng) og magnetgab. For at opnå TremorXs høje ydelse og belastbarhed er det nødvendigt at svingspolen er meget høj, dette udelukker brugen af billige standart chassiser. Ved en optimal konstruktion er helheden altid mere end summen af enkeltdelene. Den optimale XLT chassis struktur i samarbejde med membranen, ophænget, magneten og den kraftige svingspole sikrer dette perfekte harmonisk sammenspil.

Earthquake SWS-8Xi bas The Earthquake “SWS” - Shallow Woofer System- Provides more sound from less space with less power than any other woofer technology. The core technology of the SWS was pioneered by Earthquake Sound's President Joseph Sahyoun and is now protected by multiple global patents. The “SWS” design moves the flexible suspension components(cone & spider) to the side allowingthe motor to be elevated. This reduces the mounting depth of the speaker while enhancing excursion capability. More excursion (woofer movement) equals more sound.Upgrading to SWS is both attractive and simple :1. Direct factory drop-in replacement.2. Greatly enhanced sound quality. Enjoy a rich full bodied sound with articulation and dynamics rivaling home hifi audiophile systems.3. Plays louder and cleaner than standard woofer - using less power.4. Works perfectly with factory amplifier, while still capable of further SPL with upgraded amplifiers.The modern luxury car buyer expects all aspects of their vehicle to be thrilling and engaging. Thiselevates the expectations for the audio system as people now carry their music with them where ever they go - making comparisons easy. They want it to sound as good as it possibly can while being on the road. Preferably it should be so good in the car that the driver looks forward to both the ride and the music. With Earthquake SWS woofers the authentic and authoritative sound is always at the driver fingertips.Designing sound quality :“SWS” technology employs a patented ribbed cone that eliminates cone break-up distortion while maintaining a light moving mass. This keeps the woofer nimble, fast and accurate. This fast acoustic response makes the sound engaging and entices the listener to turn up the sound as it just sounds “finger snapping good”.Designing durability :“SWS” employs a revolutionary innovation that welds an aluminum voice coil to an aluminum dust cap thus turning it into a heat sink. This heat exchanger uses convection/ conduction to transfer the heat out of the box. This increases the woofer performances and ensures that heat derived compression never occurs.In short :The “SWS” will play louder and more accurate while using less power and taking up less space than any other woofer on the planet. Our most popular size is the SWS-8” as it is a direct drop-in BMW factory replacement for the woofers located under the front seats. Simply remove the seats and replace the factory woofers with the SWS-8 woofers to improve the sound quality.Earthquake Sound also produces the SWS-8Xi that has a 2Ω voice coil - the same impedance as the BMW factory speakers.

Lydkvalitet i højeste klasse - Earthquake SWS-8X Bas Earthquake SWS-8X Bas er en innovativ højttalerteknologi, der leverer mere lyd fra mindre plads med mindre strøm end andre højttalerteknologier. Patenterbeskyttet teknologi blev opfundet af Earthquake Sound's præsident Joseph Sahyoun. SWS-designet flytter de fleksible suspensionselementer (kurv og spindel) til siden, hvilket gør det muligt at hæve motoren. Dette reducerer monteringsdybden af højttaleren og forbedrer udvidelse-evnen. Jo større udvidelse (højttalers bevægelse), jo mere lyd. Opgradering til SWS er både attraktivt og enkelt: Direkte fabrikserstatning. Markant forbedret lydkvalitet med en rig og fuldendt lyd med præcision og dynamik, der kan konkurrere med hjemmets Hi-Fi audiophile-systemer. Afspiller højere og renere end standardhøjttaler med mindre strøm. Fungerer perfekt med fabriksforstærker og kan også give endnu højere SPL med opgraderet forstærker. Moderne luksusbilskøbere forventer, at alle aspekter af deres bil skal være spændende og engagerende, også lydsystemet. De bærer nemlig deres musik med sig overalt og vil have lyd, der lyder så godt som muligt i bilen. Højttalerne skal være så gode, at føreren glæder sig til både køreturen og musikken. Med Earthquake SWS højttalere er den autentiske og autoritative lyd altid lige ved hånden. Lydkvalitet design: SWS-teknologien bruger en patenteret ribbet kurv, der eliminerer kurvefejl og distorsion, mens den opretholder en let bevægelsesmængde. Dette gør højttaleren hurtig, smidig og præcis. Den hurtige akustiske respons gør lyden engagerende og frister lytteren til at skrue op for lyden, da det lyder "finger-snapping godt". Durabilitet design: SWS bruger en revolutionerende innovation, der svejser en aluminiumsvoksel til en aluminiumstøvkappe, hvilket gør den til en varmeafleder. Varmeudveksleren anvender konvektion/ledning til at overføre varmen ud af boksen. Dette øger højttalerens ydeevne og sikrer, at varme-komprimering aldrig opstå
