W3v3 FlatWedge: A Powerful Low-Profile Ported System

Right from the JL Audio factories comes a unique solution for tight spaces, integrating a highly capable W3v3 driver into a very low-profile, slot-ported design. Excellent sound quality and surprising output capability with moderate power. Featuring flared slot-port design for minimal turbulence and improved fidelity, as well as a very low-profile enclosure design that is less than 5 inches thick. An included steel mesh grill will protect your investment from any accidents.

JL Audio PowerWedge systems have defined value in engineered low-frequency systems for over ten years. Our newest models deliver enhanced power handling and are smaller than previous models, thanks to the W1v2 subwoofer drivers. Built in JL Audio's Miramar, Florida factory, utilizing state-of-the-art CNC woodworking equipment, PowerWedge systems feature top-quality MDF construction, steel-mesh grilles, five-way binding post connectors, high-grade automotive carpeting and JL Audio ECS internal wiring. If you are looking for an intense sub-bass experience without breaking the bank, these new slot-ported systems should definitely be on your short list!

This sub booms big bass for it's small size. It fits perfectly below the rear floor of my Honda CRV with the rear cargo tray removed. I power it with a 150 watt pioneer amp with the low pass filter on. Thumps Hard for it's size, and you can feel it and see the rear view mirror shake. Sufficient for me, and a completely stealth install. Bass does not thump outside the vehicle... but inside it does. Give it a try, you will be impressed.

March 1, 2010 Awesome sounding subwoofer

I have always had 2 12s or 2 10s in the past. This was a stretch for me to downsize to an 8. I have an 07 Toyota Tundra DC and this sub fits under the back seat so I can still use the back seats for passengers.
Let's talk about the sound. I was blown away by how much output this small sub puts out. I listen mostly to hip hop, some rap and rock, and these things are up to the challenge. Don't expect to feel the bass pounding away, but you can sure hear a lot, esp. for an 8!
What I like about these too is the sound quality--tight hitting bass without too much that it drowns out the mids and highs. The 8W3 is a wonderful woofer that can handle some power. I am giving them around 250 watts RMS off of a Kicker amp and they sound great!
Don't expect heart pounding bass from a single 8, but you do get some great bass, save some space, and a great quality product from JL Audio. I could fit another under the other rear seat, so I may just have to get another in the future!

I was blown away by the performance of this sub. I ended up buying two thinking that would be best but I might have over done it...can you really do that though? This sub, paired with the JL 250 1 v2 sounds absolutely incredible in my 2010 Toyota Tundra.

I would highly recommend this sub. I have a Kicker L2 in my car and these two sound just as good. Very nice!
