The Extremely Versatile SWS Subwoofers

The SWS-8XI by Earthquake Sound features a mounting depth of 2-1/8". 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. This woofer is also the perfect replacement for factory upgraded systems, especially BMW vehicles. 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 23mm 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 2.5" of space to spare then there is no other option than the SWS series subwoofer.

Awesome product!

Great set of subs to fit in your OEM BMW housing. And the 2ohms are great to give it extra boost in case your amp isn't the greatest. Just be sure to get some sort of spacer to make it fit perfectly without any problems.

Good value

I bought these speakers for my BMW E92. They are a direct replacement for the factory fitted ones and they work very well. Great speaker.

Good service but not so good product

I live out of the USA so I was not able to return the product, but one of the subwoofers had a damaged wire that we repaired locally.

Sub for lower watts amp

If you are the listener who prefer deep bass on lower volume this sub is for you. On the higher volumes it is average boom sub.
