JL Audio 13W7AE-D1.5 13.5-inch (345 mm) Subwoofer Driver, Dual 1.5 Ω

10th Anniversary Edition - W7
13.5-inch Subwoofer (1500 W, Dual 1.5 Ω voice coils)

Words like "extreme," "reference" and "ultimate" get thrown around quite a bit in the Subwoofer world, but rare is the product that can honestly lay claim to them. The 13W7AE does.
Taking the W7 design formula to its highest level, the 13W7AE offers a staggering linear excursion envelope that exceeds 1.25 inches (32 mm) one-way, along with a suspension capable of over 4-inches of peak-to-peak excursion. Combine that with a piston diameter that is 28% larger than the 12W7AE's, and you have a serious high-performance driver for the most demanding applications. With a 13W7AE, limits simply vanish and amazing sub-bass happens... on all fronts, at any level.
Our most potent Subwoofer is best used with amplifier power in the 500W - 1500W range and is optimized to operate in a 1.875 cu. ft. (53.1 l) sealed enclosure, or a 2.375 cu. ft. (67.3 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.
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

Enclosure Notes: Net volumes given above do not include the air volume displaced by the speaker (Driver Displacement). This value must be added to the net volume along with the displacement of any braces and/or ports (if applicable) to arrive at a gross internal volume. Air inside a port is not part of the effective net volume. Calculate ports as solid, not hollow objects.
* The W7’s employ a pole vent to remove heat and pressure from the inside of the speaker. This vent is located at the rear of the speaker. A minimum distance of 0.75 in (19 mm) is required between the back of the speaker and any wall of the enclosure to allow proper operation of the pole vent.
The dimensions given for the enclosure examples above take all applicable displacements into consideration
Safety Notice: It is absolutely essential that the completed subwoofer enclosure is mounted firmly to the vehicle with heavy steel bolts (0.5 in diameter) and large steel washers on both sides of the bolts. This will reduce the likelihood of occupant injury in the event of a collision or sudden deceleration.
