Features & specs

Features

Thin-Line Design: JL Audio's patented thin-line woofer technology compresses the architecture of the 10TW3-D4 subwoofer and allows it to deliver great bass performance in tight space applications (less than 3¼" 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.

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 a mica-filled, injection-molded polypropylene (IMPP) cone with a rubber surround for added durability, woofer 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 10TW3-D4 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, clean, 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.

Enclosure Compatibility

Sealed Box Volume: JL Audio recommends a 0.5 ft³ sealed enclosure. A diagram is provided in the owner's manual for a sealed box with external dimensions of 16" W x 13⅞" H x 6½" D, assuming ¾" thick material. (If you are using ⅝" thick materials, subtract ¼" from each dimension.)

Ported Box Volume: JL Audio recommends a ported box volume of 0.6 ft³. A diagram is provided in the owner's manual for a ported box with external dimensions of 30" W x 14⅜" H x 5⅛" D, assuming ¾" thick material. (If you are using ⅝" thick materials, subtract ¼" from each dimension.) A slot port is recommended with the following dimensions:

• Width: 3.625"
• Height: 2.125"
• Length: 31.0625"

Shallow Mount Design: The JL Audio 10TW3-D4 requires a mounting depth of less than 3¼".
