Description
The10TW1-4 is a powerful and innovative 10" (25cm) subwoofer. It is an exceptional product based on the patented Thin-Line subwoofer technology. This technology enables high excursion at a remarkably low installation depth and allows operation in incredibly small enclosures. With impressive features such as the free-standing cone, a motor design with DMA optimization and an installation depth of just 111mm, this subwoofer has the potential to far exceed the expectations of even the most demanding listeners. Designed and precision engineered in the USA, the 10TW1-4 clearly represents the quality and reliability that characterize JL Audio.
Features
- Based on JL Audio's patented Thin Line subwoofer technology, the 10TW1 offers a powerful combination of shallow depth and high excursion while operating in insanely small enclosures (0.35 cu.ft. / 10 liters).
- In combination with a frame made of a special cast alloy, the 10TW1 is able to work in extremely confined spaces.
- JL Audio's patented thin-line woofer technology compresses the architecture of the 10TW1 through a "concentric tube" structure built into the injection-molded cone body. This structure supports the voice coil and a fully annular spider while allowing a large motor structure to be placed further forward in the speaker than conventional designs.
- The 10TW1 also features an ingenious frame design that minimizes the frontal distance required for driver excursion. This is achieved by recessing the suspension mounting surface so that most of the frontal excursion occurs within the frame dimensions. Thanks to this feature, the 10TW1 requires only 22 mm (0.87 inches) of frontal clearance, even with the grille in place. This allows for more efficient use of space and a larger enclosure volume within a given overall depth.
- Although the 10TW1 is optimized for an enclosure that's much smaller than any other JL Audio 10-inch subwoofer system, it never sounds like a big woofer struggling in a tiny enclosure... Instead, it delivers all the rich, deep, controlled bass you've come to expect from a JL Audio subwoofer system.
