JL Audio TW1 Series 12" Subwoofer 2-Ohm 12TW1-2

Designed to excel in previously impossible spaces.

TW1 subwoofers are built in our Miramar, Florida factory and offer a powerful combination of shallow mounting depth, minimal frontal clearance and insanely small enclosure requirements. This makes them an outstanding choice for the tightest space applications.

Optimized for enclosures much smaller than any other JL Audio subwoofers, TW1’s never sound like a big woofer struggling in a tiny box... instead, they deliver all the rich, deep, controlled bass you have come to expect from a JL Audio subwoofer system.

JL Audio’s state-of-the-art Concentric Tube Suspension technology compresses mounting depth, using a “concentric tube” structure built into the injection-molded cone body, to deliver outstanding excursion capability and maximum performance potential.

TW1’s also employ a clever frame design that recesses the suspension attachment surface so that most of the forward excursion occurs within the frame’s dimensions. The result is a minimal frontal clearance of only 0.87 inches (22 mm), even with the supplied grille installed.

TW1 12-inch Subwoofer (300 W, 2 ?)

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, 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.
