JL Audio – SB-GM-TAHOCNSL/10W1v3 Stealthbox for 2007-2013 Chevrolet / GMC Full-Size SUV’s / Trucks with front bucket seats

TW1 12-inch Subwoofer (300 W, 4 ohm)

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.

– Very shallow mounting depth (4.62 in / 117 mm)

– Long linear excursion capability (0.40 in / 10 mm, one-way)
– DMA-optimized motor design
– Patented “concentric tube” architecture
– Patented “floating cone attach method” technology
– Cast alloy frame with flat edges for tight driver grouping
– Injection molded, mica-filled polypropylene cone
– Rubber surround
– Steel mesh grille included with each driver

TW5v2 13.5-inch Subwoofer (600 W, 4 ohm)

We couldn’t leave the ultimate thin woofer alone… we had to make it even better.

Our patented thin-line woofer technology compresses the architecture of the 13TW5v2 using a concentric tube structure that supports the 7-inch diameter voice coil and the suspension attachments. This permits placement of the large motor structure much further forward in the speaker than with conventional designs, while allowing excellent linear excursion capability and mechanical stability.

To unleash even more performance from this technology, the v2 improves upon the original 13TW5 with 13% greater linear excursion capability. The cast alloy chassis has also been modified for greater strength and the redesigned motor now features an annular vent. The v2 is also available in single 2 ohm and single 4 ohm voice coil versions to fit a wide range of applications.

In keeping with its ?tight-spaces? mission, the 13TW5v2 is optimized for enclosures that are far smaller than most 12-inch woofers require and only a bit larger than the air space needs of a typical, small-box 10-inch woofer. The mounting system is designed to fit in about the same footprint as a typical 12-inch woofer.

The 13TW5v2 is best used with amplifier power in the 250W – 600W range and is optimized to operate in a 0.80 cu. ft. (22.7 l) sealed enclosure.

Never has such high-quality sub-bass been possible in the most challenging installation applications.
