Tremor-X12D4 Subwoofer
The Tremor-X12D4 subwoofer is the value performance leader from Earthquake Sound. All aspects of the design have been thoroughly rationalized and optimized in every detail. Nothing superfluous added and nothing important removed. TremorX has inherited several of the key technologies from the more expensive Earthquake subwoofer lines. The result is a subwoofer peerless in its class.
Optimized in-house production allows signature strong properties at an unprecedented low price. TremorX is evidence that low price and high quality can coexist. Rational manufacturing rather than quality reduction are keywords of the TremorX design.
With Advanced Earthquake technologies such as TCT (Turbine Cooled Transducer), XLT chassis geometry, Mill-Temp aluminum voice coil, Dual symmetrical stitched tinsel leads and WE (Wide Edge) edge suspension TremorX is ready for serious low frequency combat. Solid quality and refined engineering makes TremorX a clear choice for the price and performance oriented enthusiast.
High-Performance Voice Coil
The heart of Tremor-X12D4 subwoofer is an oversized voice coil. All aspects of the voice coil design is optimized for maximum performance, durability and sound quality. The voice coil former (the cylinder to which the coil is wound) is made of aluminum, not cellulose (cardboard), Kapton ® or fiberglass. The use of aluminum prevents hotspots on the voice coil - due to the superb heat conductivity inherent to aluminum. In essence the entire voice coil becomes one big heat sink. The voice coil is wound of copper wire and meets mil-std specifications for temperature resilience. German made high temperature adhesives are used to fuse the coil to the former. This guarantees peak performance even during hard and continuous operation.
TCT - Turbine Cooled Transducer
TremorX 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 harder you drive TremorX the more it cools itself.
WE-Wide Edge suspension
The Wide Edge suspension allows significant excursion without deformation or increased mechanical resistance. The suspension is of the single-roll type and is thermally pressed for extreme strength and mobility. It allows cone travel of more than 35 mm. This ensures perfect reproduction of even the most bass heavy soundtracks.
Black-Top TX Cone
The TremorX cone is made of strong space age polymer and obtains additional rigidity by its geometric shape. The cone does not flex or deform regardless of input power and frequency.
Dual Symmetric Stitched Tinsel Leads
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.
XLT Chassis Geometry
TremorX 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. And it is designed to accommodate oversized spiders and voice coils.
