## 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: Finally my F34 sounds good - Simply replacing the stock subs in a Hi-Fi system makes a huge difference. Now subbas is present even without adjustments in bass menu. Finally I'm enjoying my car's sound!
Review: Pure thumping bliss - I paired these up with the JL Audio xd600/6 crossed at 120 hz and it is pure audio bliss. The bass is thick and rich. Is not club style throbbing bass for EDM, but for rock, funk, disco, soul, it is excellent— tight, articulate and powerful. Everybody who I demonstrate my car audio comments on how clear and tight it sounds and I get immense enjoyment from listening to it every day. The only thing to be aware of is that as other people have commented, you need to be prepared to creatively make the area on top of the subwoofer provide an inch or so more clearance for the subwoofer to move back-and-forth without hitting the grill. I accomplished this by putting a piece of wood as a spacer on the two sides of each subwoofer and then getting extra long 2 inch screws to screw the grill back in. It is completely not noticeable after closing everything up because this area ends up being entirely under the seat.

### ⭐⭐⭐⭐ Recommended for those with a BMW
*by R***K on January 23, 2015*

"Almost" a drop-in sub for my BMW. Just had to shave a few items down in order for them to fit. Simple enough though. No real cutting or drilling to make these work. Good Stuff!
