Earthquake SWS-8

Earthquake Sound Corporation is the original inventor of the Shallow Woofer System (SWS) that produces a lot of bass from a small space. Protected by 3 U.S. Patents, Earthquake Sound manufactures the SWS woofers in 5 different sizes (6.5”, 8”, 10”, 12” and 15”) with 4W impedance. 

Our most popular size is the SWS-8 due to the fact that it is designed to replace the BMW factory speakers that are located under the front seats. There is no modification required. Simply remove the seats and replace the factory woofers with the exact-fitting SWS-8 woofers to improve the sound quality of your mobile audio.

Since many OEM amplifiers are now coming with a 2-Ohm impedance, Earthquake Sound have also released the SWS-8Xi that has a 2-Ohm voice coil aswell as this SWS-8 subwoofer which has a 4-Ohm voice coil.  

In addition to BMW cars, the SWS series are the perfect BASS solution for any car. Many factories are now using woofers in small areas. To improve your bass, simply replace the factory speakers with the SWS woofers.
