Features
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.
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.
