JL Audio CP112LG-TW1-2 # 93326 Single 12TW1 MicroSub, Ported
This incredible JL Audio CP112LG-TW1-2 subwoofer system delivers the kind of output and extension that is normally possible with only much larger systems. The key to its performance lies in the precise tuning of its 12TW1 subwoofer driver into an efficient slot-ported design.
Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure’s internal volume relative to its exterior volume. The port wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The flared port entry and exit further enhance sound quality by minimizing air-flow noises through the port.
This subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal.
Finish: Black, high-grade automotive carpet with silver “JL AUDIO” embroidery on front baffle. A steel mesh grille is included to protect the subwoofer driver.
The TW1 subwoofer drivers offer an unparalleled combination of shallow mounting depth, nominal frontal clearance and extremely small enclosure requirements, making them an outstanding choice for tight-space, moderate power applications. They are the perfect bass solution for muscle cars, small cab trucks or any other application that requires JL Audio performance in an ultra-compact space. The driver achieves this extreme level of shallow-depth by compressing the architecture of the TW1 using a concentric tube structure that supports the oversized voice coil and the suspension attachments. This permits placing the large motor structure much further forward in the speaker than with conventional designs, while maintaining excellent linear excursion capability and mechanical stability. In addition, the DMA-optimized motor system produces a consistent motor force over a long range of strokes and power levels. Those strokes don’t prevent the driver from remaining compact, however, thanks to the 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 architecture. Although the TW1 Subwoofer can be driven with as little as 75 Watts, for best audio performance it is recommended to run an amplifier capable of between 200 – 300 Watts of continuous power per driver.
