1x JL Audio 12W7AE-3:12-inch (300 mm) Subwoofer Driver 3 Ohm (12W7AE-3)
12W7AE-3
10th Anniversary Edition - W7 12-inch Subwoofer Driver (1000 W, 3 Ω)
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. 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 are they 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.
