Feel the Earth Move and Quake with Tremor-X Subwoofers

The TREMOR-X154 15" 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.

older was better

Had the old red ones and they lasted 3 years or so with no issues and they were less wattage. New ones lasted less than 5 months, tuned by professional car audio dealer. They pounded while they lasted, going with another brand now.

tremor-x158

Just got these low priced beasts. Let me tell you they are just that. Tight accurate bass even in a ported box. Definitely worth the money. I have two on a cruddy American legacy la1990 amp and they pound. Will buy two more an a better amp soon. Thanks Sonic!
