JL Audio W7-Series 12-Inch 1000-Watt Subwoofer Driver, 3-Ohm SVC
The JL Audio 12" W7AE audiophile reference subwoofer driver delivers the ultimate performance by combining long-excursion W7 driver design with a large 12-inch bore. It has been called "addictive," "seductive" and "the new subwoofer reference", with limitless dynamics and exceptional balance and world-class sound quality.
This 12W7AE automotive reference sub is best used with an amplifier in the 400-Watt - 1000-Watt 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.
The JL Audio 12W7AE-3 (Anniversary Edition) subwoofer 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
