JL Audio 8W7AE 500W 8" 20cm Anniversary Edition Subwoofer Bass Driver

10th Anniversary Edition - W7 8-inch Subwoofer Driver (500 W, 3 Ω)

This subwoofer driver has been called the "best damn 8-inch subwoofer ever made" for its remarkable performance capabilities and design attributes. An impressive linear excursion envelope that exceeds 0.75 in. (19 mm) one-way allows it to deliver impact well beyond the range of other 8-inch subwoofer drivers.

The 8W7AE is best used with amplifier power in the 200W - 500W range and is optimized to operate in a 0.875 cu. ft. (24.8 l) sealed enclosure, or a 1.0 cu. ft. (28.3 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 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

2011 marks the tenth anniversary of JL Audio's flagship W7 automotive subwoofer drivers. To commemorate this occasion, each W7 model is now offered in special "Anniversary Edition" (AE) trim, which includes a satin black frame finish, a bright-anodized trim ring and special badging.

Once you begin to analyze the technology and the performance envelope of a JL Audio W7AE, you realize that these are much more than just 'big SPL speakers'.

The W7AE embodies JL Audio's commitment to pushing the envelope of speaker technology, with six patented technologies and a completely unique set of component parts. Each W7AE model has been meticulously engineered to reproduce sub-bass with extreme fidelity at any volume level.

The final product is a completely original design from surround to back-plate, requiring a significant tooling investment for all of the component parts. Each individual W7AE model is a completely unique design and shares no major parts with its siblings, because each motor and each suspension system is specifically designed and tuned for that model. Even the bolts and screws used to assemble the speaker have been purpose-designed and manufactured to JL's specifications.

The result is the ultimate subwoofer driver... one which can thrill you equally with finesse or brute force and delivers a musical listening experience like no other.
