Features & Specifications




JL Audio 10TW1-4 thin line 10″ 4-ohm subwoofer #92186

The JL Audio 10TW1-4 subwoofer drivers offer an unparalleled combination of shallow mounting depth, nominal frontal clearance and extremely small enclosure requirements, making them an outstanding choice for tight-space, moderate power applications. They are the perfect bass solution for muscle cars, small cab trucks or any other application that requires JL Audio performance in an ultra-compact space. The driver achieves this extreme level of shallow-depth by compressing the architecture of the TW1 using a “concentric tube” structure that supports the oversized voice coil and the suspension attachments. This permits placing the large motor structure much further forward in the speaker than with conventional designs, while maintaining excellent linear excursion capability and mechanical stability. In addition, the DMA-optimized motor system produces a consistent motor force over a long range of strokes and power levels. Those strokes don’t prevent the driver from remaining compact, however, thanks to the frame design that minimizes the frontal clearance required for the excursion of the driver. This is accomplished by recessing the suspension attachment surface, so that most of the forward excursion occurs within the frame’s architecture. It is because of all these ground breaking achievements that JL Audio chooses the TW1 to provide the voice for many of their PowerWedge series enclosures and Stealthboxes.

Compact sub on a mission

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.
