JL Audio – SB-D-5GRAMQC/10TW3 Stealthbox Enclosed Subwoofer for 2020-Up RAM 1500 Quad Cab

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 10-inch Subwoofer (750 W, 3 ohm)

If you are seeking reference-grade sub-bass from a 10-inch driver, your search ends here. Total Car Audio in the UK called it like this when they reviewed the 10W7: “This gives an all round performance of such high quality on every level, that bettering it will be very hard to achieve.” Not only does the 10W7 deliver amazing excursion capability for its size, but it also maintains complete composure under power and is able to track complex bass material with uncanny accuracy and power.

The 10W7AE is best used with amplifier power in the 300W – 750W range and is optimized to operate in a 1.25 cu. ft. (35.4 l) sealed enclosure, or a 1.5 cu. ft. (42.5 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
