## Description

Earthquake Sound Corporation is the original inventor of the Shallow Woofer System (SWS) that produces a lot of bass from a small space. They are a popular choice for replacing OEM car speakers with shallow mounting depths. In addition to OEM applications, 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 no need for extensive modifications to accommodate large subwoofers.

Review: Happy with purchase. - The setup in my 2014 4Runner. Running a 5 channel NVX amplifier. Focal 6.5 in doors and tweeter in factory locations. 2 Dayton Audio 8” subwoofers in ported box. I wanted to add a front subwoofer for mid bass. Was able to make a box for under front drivers seat, with .2 CU FT. played with different crossover points and settled on high pass at 50HZ. Low pass at 120. Output was no problem. Had to turn down the amp gain to match the other speakers. Sounds great and gives an extra punch the brings the bass up front. Also acts as a bass shaker under my seat. I feel like it is built well. I like that it can go in a small sealed box. Base does roll off below 50HZ. My amp is rated at 150 watts bridged. It does not clip with my setup. Over all I’m impressed. Would buy again.
Review: Waste of money - Really no difference then stock

### ⭐⭐⭐⭐⭐ Great bang (literally) for your buck!
*by B***R on February 5, 2017*

I got 2 of these to replace the factory under seat woofers in my BMW. For what it is, it really makes great bass, certainly much better then the boomy and soft sounding Harmon Kardon system that came with the car. So instead of just hearing deep sounding bass, you can now feel it. On top of that, the factory speakers can't reproduce the really low bass. From my experience, the bass rolls off at nearly 100hz! So anything under 100hz, you can barely hear it. With the new amp and these speakers, you can hear all the way down to 20hz. You can FEEL it all the way down 20hz. Of course, these will never be as powerful as a 12" sub box in the trunk, but if need as much trunk space as I can get, then these should satisfy your bass needs without sacrificing any trunk space. FYI, I paired this with a Kenwood 500W (@2ohms) mono amp and it's a great match. A mistake many people make is getting an amp to match the speakers RMS handling 1:1. However, to properly power subwoofers, you will want an amp that's 1.5x to 2x the RMS handling power. Also, if you're putting this is the BMW F30, you will need the adapters and remove the little "fins" inside the sub enclosure to make this it properly.
