JL Audio 12TW3-D4

Shallow-mount 12" subwoofer with dual 4-ohm voice coils

Bass for challenging spaces

If you've got a pickup truck, sports car, or you just need to haul a lot of stuff, then you know that adding some bass can be a challenge. That's why JL Audio built the TW3 Series 12TW3-D4 shallow-mount subwoofer. This super-thin 12" sub puts out big bass, yet only requires minimum air space, so you can use a much smaller enclosure. Now, you can have your bass and your space too.

JL Audio's amazing engineering

JL Audio used all their tricks to build a sub this slender without giving up performance. Its tough polypropylene cone won't flex under high power, and the large, durable rubber surround helps the cone move large amounts of air. The heavy-duty cast-alloy frame only stands 3-1/2" tall, but provides a stable home for this high-performance bass driver. For best results, you'll want to send this sub up to 400 watts RMS, and its dual 4-ohm voice coils make it a perfect match for a mono amplifier.
