Feel the Earth Move and Quake with Tremor-X Subwoofers

The TREMOR-X128 12" single 8 ohm subwoofer by Earthquake Sound is the kind of woofer no car audio enthusiast should be without. Its pressed pulp fiber cone and high-roll rubber surround provide sturdiness, rigidity, and increased performance, while the Turbine Cooled Transducer technology keeps the voice coil at lower temperatures for longer and louder bass reproduction. The woofer also features an anti-wobble cone construction and reinforced dust cap construction for improved linear movement, thus creating a nice steady bass at any volume level. Its spring-loaded terminals offer a quick and simple installation while the thick density magnets offer better efficiency. This Tremor-X series subwoofer has everything you need from a subwoofer and it's even marine compatible for installation on boats, not many other woofers can say that. In today's economy this woofer is the best bang for your buck.
