The Extremely Versatile SWS Subwoofers

The SWS-12X by Earthquake Sound features a mounting depth of 3". With a depth this small the applications for this woofer are endless. This shallow-woofer-system series subwoofer is perfect for those with limited space but that still want some bass in their car. The woofer features a light weight resistant PVC cone and a long-lasting UV treated high-roll composite foam surround for added rigidity, stiffness, longevity and increase power output and performance. Don't let the size of the woofer fool you into thinking it's not powerful, with an Xmax linear excursion of 31mm this woofer will hit low-frequencies with accuracy and precision for a clean, crisp, and responsive bass reproduction. Although often imitated the SWS's 3 protected U.S patents assure that it's never duplicated. If you have 3" of space to spare then there is no other option than the SWS series subwoofer.

I just got an email that said ive had this sub for 6 months. Sounds about right i guess. It sounds great. I mounted it into a sony slim box and it seems to hit with a deeper bass than the sony. Doesn't buzz as much either, nice and clean bass.
