About the JL Audio 10TW1-4
Compact sub on a mission
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.
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.
To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Thin-Line Design: JL Audio's patented thin-line woofer technology compresses the architecture of the 10TW1-4 subwoofer and allows it to deliver great bass performance in tight space applications (less than 4-3/8" deep). Central to the technology is the Concentric Tube structure that supports the oversized voice coil and the suspension attachments. This permits placing the motor structure much further forward in the speaker than conventional designs, while maintaining excellent linear excursion capability. Equally important, the 10TW1-4 is designed for extremely small enclosure applications (0.35 ft³ sealed and 0.625 ft³ ported) and there is no pole vent, so no space is needed between the woofer and the back of the enclosure.
Concentric Tube Suspension: JL Audio's patented Concentric Tube Suspension employs a molded structure which spans beyond the edge of the motor structure, supporting the spider on the outside of the motor's boundaries and the large diameter voice coil on the inside. The large voice coil permits the magnet to sit inside it, rather than surrounding the coil as is typical in most woofers. The concentric tube structure and the elimination of a conventional top-plate helps JL Audio place the motor higher up into the cone body's space to further compress depth, while still permitting excellent mechanical excursion.
Mica-Filled Polypropylene Woofer: The subwoofer features an injection-molded, mica-filled polypropylene cone with a rubber surround for added durability, excursion and bass response.
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 10TW1-4 motor remains linear over a long excursion range, and also maintains a stable fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, articulate bass.
Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
Sealed Box Volume: JL Audio recommends a sealed box volume of 0.35 ft³. A diagram is provided in the owner's manual for a sealed box with external dimensions of 16-1/8" W x 14" H x 5-1/4" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, subtract 1/4" from each dimension.)
Ported Box Volume: JL Audio recommends a ported box volume of 0.625 ft³. A diagram is provided in the owner's manual for a ported box with external dimensions of 26-5/8" W x 16" H x 5-1/4" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, subtract 1/4" from each dimension.) A slot port is recommended with the following dimensions:
- Slot Width: 3-3/4"
- Slot Height: 1-7/8"
- Slot Length: 22-1/2"
