JL Audio 8W7AE-3, W7 Series 8" 3-Ohm Subwoofer, 500W
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. 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
Dynamic Motor Analysis - DMA Optimized Motor
JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.
Elevated Frame Cooling (U.S. Patent #6,219,431 & #6,229,902)
JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
Floating Cone Attach Method - FCAM™ (U.S. Patent #6,501,844)
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
W-Cone (U.S. Patent #6,496,590)
The W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.
OverRoll™ Surround
By utilizing space wasted in conventional speakers, this ground-breaking innovation controls the W7's massive excursion without sacrificing precious cone area.
Radially Cross-Drilled Pole-Piece (U.S. Patent #6,243,479)
This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil. This improves power handling and reduces power compression effects, leading to more linear performance.
Engineered Lead-Wire System (U.S. Patent #7,356,157)
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
Built in U.S.A. with Global Components
JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
