The 12TW1-2 is an impressive 12-inch subwoofer from JL Audio. This technologically advanced subwoofer is based on the patented Thin-Line Subwoofer Technology, offering a powerful combination of shallow mounting depth and high excursion. With the ability to operate in unusually small enclosures and a specially tuned cast frame, the 12TW1-2 sets new standards in efficiency and performance. Despite its compact size, this subwoofer delivers the rich, deep, and controlled bass that JL Audio is known for. Designed and manufactured with strict quality standards, the 12TW1-2 is a true breakthrough in audio technology.
Features
- Based on JL Audio's patented Thin-Line Subwoofer Technology, the 12TW1 offers a powerful combination of shallow mounting depth and high excursion while operating in insanely small enclosures (0.65 cu.ft. / 18.4 liters).
- Combined with a frame made of a special cast alloy, the 12TW1 is capable of operating in extremely tight volumes.
- JL Audio's patented Thin-Line woofer technology compresses the architecture of the 12TW1 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 the placement of a large motor structure further forward in the speaker than with conventional designs.
- The 12TW1 also features an advanced frame design that minimizes the frontal clearance required for driver excursion. This is achieved by recessing the suspension attachment surface so that most of the excursion occurs forward within the frame dimensions. Thanks to this feature, the 12TW1 requires only 22 mm (0.87 inches) of frontal clearance even with the grille mounted. This allows for more efficient use of space and greater enclosure volume within a given overall depth.
- Although the 12TW1 is optimized for an enclosure much smaller than any other 12-inch subwoofer from JL Audio, it never sounds like a large woofer struggling in a tiny box... instead, it delivers all the rich, deep, and controlled bass you expect from a JL Audio subwoofer system.
