JL Audio 10W7AE-3

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. 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

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.

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.
