JL Audio 92117 W7AE 8" Subwoofer Driver
This Subwoofer 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 Subwoofers.
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.
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:
Key Features:
- Satin-Black Powdercoated Baskets
- Bright Anodized Surround Clamp Ring
- Anniversary Edition Cone Badge
- Anniversary Edition Terminal Label
Features:
- Highly Linear, DMA Optimized Motor System
Highly optimized motor system delivers linear motor force over a wide range of excursion and power levels to reduce distortion - Ultra-Long Voice Coil
To create an extreme linear range of operation, resulting in high output with minimal distortion - W-Cone
A unit-body cone assembly that delivers astonishing cone stiffness with minimal mass - OverRoll
Utilizes space wasted in conventional designs to maintain cone area while permitting a large surround - Elevated Frame-Cooling
Provides additional cooling by directing air flow over the top-plate and onto the voice coil windings - Radially Cross-Drilled Pole-Piece
An innovative venting system which greatly enhances power handling by directing air flow into the voice coil gap - Floating Cone Attach Method
Ensures proper surround geometry and moving parts alignment in the assembled speaker - Plateau-Reinforced Spider Attachment
Provides strain relief for the spider material at extreme excursion levels. - Huge Diameter, Progressive-Roll Spider
Provide precise centering and linear compliance over a wide range of excursion to further reduce distortion. - Co-Extruded, Double Lead-Wires
Carefully engineered lead wire system controls motion and relieves stress without compromising spider linearity.

Footnotes:
- * 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”.
