JL Audio – SB-GM-C7CP2/10TW3 Stealthbox For 2014-Up Chevrolet C7 Corvette Coupe (Dual Driver)

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.

10th Anniversary Edition – W7 12-inch Subwoofer (1000 W, 3 ohm)

The 12W7AE brings serious performance to the table by combining the breakthrough of the long-excursion W7 design with a large 12-inch bore. It has been called “addictive,” “seductive” and “the new subwoofer reference”, by some of the world’s toughest reviewers, and has earned these accolades by delivering nearly limitless dynamics, exceptional balance and world-class sound quality.

This potent driver is best used with amplifier power in the 400W – 1000W range and is optimized to operate in a 1.375 cu. ft. (38.9 l) sealed enclosure, or a 1.75 cu. ft. (49.6 l) ported enclosure.

W7AE (Anniversary Edition) Subwoofers celebrate the 10th Anniversary of the launch of the W7 subwoofers. Functionally, they are identical to the original W7’s, but they are distinguished by the following cosmetic differences:

– Satin-Black Powdercoated Baskets
– Bright Anodized Surround Clamp Ring
– Anniversary Edition Cone Badge
– Anniversary Edition Terminal Label
