JL Audio W7AE 10" Subwoofer Driver - 010-03208-00

JL Audio 92114 W7AE 10" Subwoofer Driver

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.

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:

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”.
