Feel the Earth Move and Quake with Tremor-X Subwoofers

The TREMOR-X104 10" single 4 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.

perfect for standard cabs

I currently have 2 in a 2.5Cu Ft (total) 1.25Cu Ft (each chamber) sealed box only getting 200w rms each right now for the break in period and they are already louder and clearer then my previous kenwood performer 12in 400w rms which i had in a 2Cu Ft ported box cant wait to finish the 20Hr break in period then really turn them up.

Great value

For a low level entry sub they are real nice Sq and Spl. I am still in the break in period so i cant go to hard on them yet but they are definately worth the value. I am running a rockford fosgate 500-1bd to them in a ported 1.22 cu ft Box. Have to say I think im going to try the Dbxi version when im done with these

A 10" with low end SLAM

I retired my TNT-10S in good nick, for this Tremor-X104. Direct swap with no mods. In a sealed enclosure, this sub is lazy, meaning it takes a lot of wattage to get it slamming, because of its low sensitivity.

But what amazes me on each listen, is the detail it picks up. More defined and musical than I expected. I have 475W rms on it, and it is easily the best sub I've heard for sound quality with high volume. It reproduces all kinds of sharp transitions and never has a mushy blurry sound, always super tight bass that shakes your mirrors and seat.
If your amp has a 40 hz boost, tune it and grin. Amazing how a smaller sub can hit like a hammer. Earthquake Sound made a real value with this one.
