Flat sub, full-sized performance!!!

This has to be the best flat sub woofer on the market in terms of value and performance. This sub woofer can be used in very small sealed enclosures, and being a flat sub it surprisingly works well in a ported enclosure as well! I built an enclosure in my 08 Sport Trac, built to manufacturer specs, and it is loud, accurate, and handles lots of power.

Great Product

These speakers don't lack quality or sound due to the slim style! Excellent product and a great value!

Great Sub!!

I have a 12" 2ohm svc version of this sub in the trunk of my SC300... Just one... powered by a JL audio 500/1 amp...and it surprised me.... I am planning on getting two 10" and power them by another JL 500/1 amp for my 08 Tahoe.... This sub requires minimal air space and thumps pretty hard... It is NOT just a pickup truck speaker... and a one in the trunk will rattle your rear view LOL...

Great Value!

Great sub for the price. Sounds good but do not over power it. I fried mine just running 500W RMS.

Great Product

Very High Sensitivity - good thing! Rolls off steeply at 35Hz. Just perfect for my application. Great for spare wheel well install. Need Poly-fil to maximize bass output. Running 350 RMS. No problems yet.

By Edge on March 2, 2010


Wow this sub was surprising! I currently have one running under the back seat of my f150 in a custom box with an rms of 300 watts. IT sounds great. It doesn't have that much thump as I have noticed with regular sub but its sound reproduction was very noticeable. IT does a great job on reproducing low notes and sounds great with rap, hip hop, country, rock, pop you name it.
