Compact sub on a mission

Advances in fabrication result in compact efficiency.

JL Audio designed their TW1 subwoofers for tight spaces and tiny enclosures. Their 10TW1-4 10" subwoofer operates efficiently in an enclosure of only 0.35 cubic feet and, at only 4-3/8" deep, this workhorse will fit in all kinds of tight spots you wouldn't expect a subwoofer to go. You can power this sub with up to 300 watts RMS, so it's perfect for medium-sized systems.

Unique construction

The injection-molded mica-filled polypropylene cone with its rubber surround is housed in a specially designed cast-alloy frame, while JL Audio's patented concentric tube suspension allows the speaker's components to fit together more closely for a smaller profile. If you're looking for a subwoofer that brings maximum boom to minimal space, you're looking in the right place.
