JL Audio 92187 12" Subwoofer Driver
Built on JL Audio's patented thin-line subwoofer technology, the 12TW1 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 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 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 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.
Even though the 12TW1 is optimized for an enclosure much smaller than any other JL Audio twelve-inch subwoofer driver, 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.
Key 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
Features:
- Dynamic Motor Analysis - DMA Optimized Motor
JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. - Engineered Lead-Wire System (U.S. Patent #7,356,157)
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands. - Tab-Ear Frame Design
This frame design feature facilitates mounting the Subwoofer in tight spaces. - Concentric Tube Suspension
Our Concentric Tube Suspension™ technology delivers unprecedented excursion in a low-profile woofer. - Built in U.S.A. with Global Components
JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.

Footnotes:
- * Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
- ** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
