JL Audio quality in a thin package

The PowerWedge CS112LG-TW3 enclosure pumps out signature JL Audio bass from a small sealed box. Install it anywhere that you might have a little room, like behind a seat or in the trunk, add an amp, and enjoy the extra depth that good bass will add to your system.    

Immense bass

JL Audio used their extensive engineering know-how to build a super-thin TW3 subwoofer that offers big performance. This PowerWedge handles up to 400 watts RMS, housing one 12" TW3 subwoofer that pounds out impressive low end. The enclosure is matched to the sub for optimum output, and the airtight sealed design delivers powerful, accurate bass.

This enclosure's slender profile means it'll fit behind seats or in other tight spaces.

Solid MDF enclosure

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure, then finishes it with rugged automotive carpeting, nickel-plated push terminals, and solid internal wiring. The enclosure is inspected by hand at the manufacturing facility in Florida to ensure that you get the bass that you expect from JL Audio.

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Speaker is so bassy and clear sounding. Low bass and thumps so hard. Small area that it takes up. Would love to have two.

Pros: Size, quality, sound, craftsmanship. Etc. .

Cons: No cons from me

What is there to say? This thing bangs. I have it running a mere 300RMS through a small Kenwood 5001 and I have no complaints. Other than I'm sure my rear view mirror will fall off in the near future. It fits well in most places, DOUBLE CHECK YOUR DIMENSIONS! I don't know why I thought this would fit anywhere else in my car, but thats my own fault for not measuring.

The response is SUPER clean, pretty much everything about this sub is wonderful.

2009 Mini Cooper Clubman Kenwood 5001 JL Audio TW3 12" Pioneer Speakers all around.

Pros: BOOM, BOOM. BOOM, clean, perfectly sized box, compact, It's JL Audio

Cons: Speaker grille is hard to get off? ONLY complaint. I need it off for my set up and I'm worried about breaking it trying to get it off. Other than that, nothing!
