## 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: Good woofers. - These are good woofer replacements for doors. Be sure to get low pass crossovers. They take a week to break in. First day not much bass. Second week these kick in. Lots of strong bass. Also, be sure they are sealed around surface mounting area.

### ⭐ Not good speakers, go elsewhere
*by S***R on December 24, 2023*

I have run 2 of these off a Kicker Key500.1, set gains with my Fluke DMM to 100w RMS a piece to see how they handle better power than BMW HiFi amp (40w RMS a piece). I had to basically not send any power at these at all, they start cooking pretty bad. I have headaches when I drive from the glue burning up on the voice coils. They just dont stay cool. I also run an RE Audio XXX 12" on 2000-2400w RMS in same vehicle. The SW8s were more for 60-150hz and my XXX for 25-60hz. Either way, there is no way they could ever handle 150w RMS a piece. Not happy with these at all. I will probably buy a couple Kicker 8" L7Ts and fabricate custom enclosures under the seat for them for what Im looking for, and send those an actual 500w. Read positive things, but as an installer, I have blown 2 subwoofers. 1 was over 20 years ago on my second install for a buddy in high school. The second was because a customer insisted on me using a crummy $75 used Crunch walmart amp to try and send some Planet Audio 15s 2000w (some of the worst amps in the market). If you run an unclipped signal to these, I wouldn't push em past 60w a piece, they simply cannot handle any power. They sound alright, but after 1 minute I cannot stand the voice coils burning up. These speakers are not for me.
