JL Audio 10TW1 -2

Discover the 10TW1 -2, a 10" (25cm) subwoofer from JL Audio, based on the company's own Thin Line subwoofer technology. This powerful subwoofer combines low installation depth with high projection and works even in extremely small enclosures. Thanks to innovative technology and the patented design, the 10TW1 -2 can be placed in very tight spaces without compromising the front distance required for the driver's excursion. Despite its small format, the 10TW1 -2 the rich, deep and controlled bass you expect from a JL Audio subwoofer.

• The 10TW1 , based on JL Audio's patented Thin Line subwoofer technology, 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 able to work in extremely tight spaces. 
• JL Audio's patented Thin-Line woofer technology compresses the architecture of the 10TW1 by 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 in conventional designs.
• The 10TW1 also features a sophisticated frame design that minimizes the frontal distance required for the driver to travel. This is achieved by deepening the suspension mounting surface so that most of the forward travel occurs within the frame dimensions. Thanks to this feature, the 10TW1 Even with the grille installed, there is only 22 mm (0.87 inches) of frontal clearance. This allows for more efficient use of space and a larger enclosure volume within a given overall depth.
• Although the 10TW1 Optimized for an enclosure 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.
