JL Audio 12TW1-4 12" 300 Watt 4 Ohm Subwoofer – #92187

Product Descriptions

JL Audio 12TW1-4 12" Thin-Line Single 4-ohm Subwoofer #92187

The 12TW1-4 delivers a powerful combination of shallow mounting depth and excursion capability, while operating in insanely small enclosures (0.65 cu.ft. / 18.4 liters). This, combined with a special cast alloy frame design, makes the 12TW1 capable of operating in extremely tight spaces. These include under-seat installations in trucks, 2-seat sports cars and many other creative applications requiring a compact, low profile subwoofer design. JL Audio's patented thin-line woofer technology compresses the architecture of the 12TW1-4 using a "concentric tube" structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of a large motor structure further forward in the speaker than with conventional designs. The 12TW1-4 also features a clever 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 dimensions. Thanks to this feature, the 12TW1-4 requires only 0.87 inches (22 mm) of frontal clearance, even with its grille installed. This allows for more efficient use of space and increased enclosure volume within a given overall depth.

Compact sub on a mission

JL Audio designed their TW1 subwoofers for tight spaces and tiny enclosures. Their 12TW1-4 12" subwoofer operates efficiently in an enclosure of only 0.65 cubic feet and, at only 4-5/8" 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. Even though the 12TW1 is optimized for an enclosure much smaller than any other JL Audio twelve-inch Subwoofer, it never sounds like a big woofer struggling in a tiny box...instead, it delivers all the rich, deep, controlled bass you have come to expect from a JL Audio subwoofer system.

12TW1-4 Features:

  • Very shallow mounting depth (4.62 in / 117 mm)
  • No pole vent: permits mounting close to rear wall of enclosure
  • Extremely small sealed enclosure volume requirements
  • Long linear excursion capability (0.40 in / 10 mm, one-way)
  • DMA-optimized motor design
  • Patented "concentric tube" architecture
  • Patented "floating cone attach method" technology
  • Cast alloy frame with flat edges for tight driver grouping
  • Injection molded, mica-filled polypropylene cone
  • Rubber surround
  • Steel mesh grille included with each driver
  • Precision-built in USA at JL Audio’s Miramar, Florida factory with global components

Concentric Tube Suspension

JL Audio's patented solution to overcome the lack of mechanical clearance, presented by "low profile subwoofers", employs a molded structure which spans over the edge of the motor system, supporting the spider on the outside of the motor's boundaries and the large diameter voice coil on the inside. The large diameter 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 place the motor system higher up into the cone body's space to further compress depth, while still permitting excellent mechanical excursion.

Phenomenal Control

DMA is JL Audio’s proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, TW1 motors remain linear in motor force over an extreme range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. Its main catalyst is the driver's Ultra-long Voice Coil, that allows extreme linear excursion, phenomenal power handling and control, control, control.
