About the JL Audio 12TW3-D8

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-D8 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.

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-D8 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.

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. The sub's dual 8-ohm voice coils give you additional options for connecting one or more subs. For best results, you'll want to send this sub up to 400 watts RMS.

Features

Thin-Line Design: JL Audio's patented thin-line woofer technology compresses the architecture of the 12TW3-D8 subwoofer and allows it to deliver great bass performance in tight space applications (less than 3½" 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 maximizing 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 maximizing 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 12TW3-D8 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 1.0 ft³ sealed enclosure. A diagram is provided in the owner's manual for a sealed box with external dimensions of 25" W x 16⅝" 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 1.3 ft³. A diagram is provided in the owner's manual for a ported box with external dimensions of 34" W x 17" H x 6¾" 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: 5¼"
  • Height: 2⅜"
  • Length: 24"

Shallow Mount Design: The JL Audio 12TW3-D8 requires a mounting depth of less than 3½".

Q
Is it 4 ohm or 8 ohm?
[ Fahad  May 17, 2019 ]
1 answer
A
It has dual 8 ohm voice coils so you would likely wire it in parallel to 4 ohms.
