JL Audio 10W7AE-3 #92114 Anniversary Edition 10-inch Subwoofer
If you are seeking reference-grade sub-bass from a 10-inch driver, your search ends here JL Audio 10W7AE-3. Not only does it 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 JL Audio 10W7AE-3 subwoofers utilize a patented W-Cone design; the unit-body cone assembly maximizes cone stiffness with minimal mass. The shape also provides torsional rigidity, critical to maintaining voice coil alignment at the suspension limits. Two lightweight mineral-filled polypropylene skins are bonded together at the perimeter and the center of the assembly. The lower skin’s cross-section is shaped like a W and the upper skin is the part of the cone visible from the top.
OverRoll Surround technology allows JL Audio 10W7AE-3 to make use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means the oversized surround can support greater x-max without sacrificing cone area. An added benefit is that the mounting holes are sealed by the surround, resulting in an improved box seal.
Ultra-Long Voice Coil
The JL Audio 10W7AE-3 subwoofers feature an ultra-long voice coil to enhance linear excursion, power handling and control. The large surface area of the coil offers excellent heat dissipation, while the winding height provides the necessary motivational force to achieve the excursion of the W7AE design.
Floating Cone Attachment Method (FCAM)
JL Audio’s patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
Dynamic Motor Analysis (DMA)
DMA is JL Audio’s proprietary analysis method aimed at improving dynamic motor behavior. As a result of DMA optimization, W7AE motors remain linear in motor force over a long range of excursion, and also maintain a stable fixed magnetic field in the gap over a wide power range. This leads to reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
Forced Air Cooled
The elevated frame design of the W7AE delivers cool air through slots directly above the top-plate to the voice coil. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
Radial Cross-Drilled Pole Piece
This venting system enhances heat dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Forced Air Cooling technology.
The large, progressive-roll spider provides precise control and motor/voice coil alignment without limiting excursion prematurely.
Plateau-Reinforced Spider Attachment
A derivative of JL Audio’s VRC technology, this suspension attachment relieves stress from the spider material at high excursions for enhanced reliability.
Co-Extruded Double Lead Wires
The extruded casing and carefully engineered attachments ensure controlled lead-wire behavior under the most extreme excursion demands. Two conductors are used per connection for ample current carrying capability.
The recommended sealed box volume is 1.25 cubic feet; a diagram is provided in the owner’s manual for a sealed box with external dimensions of 15.5″ W x 14.0″ H x 15.0″ D, assuming 3/4″ thick box material (If you are using 5/8″ thick materials, you should subtract 1/4″ from each dimension).
The recommended ported box volume is 1.5 cubic feet; a diagram is provided in the owner’s manual for a slot ported box with external dimensions of 23.375″ W x 13.5″ H x 14.5″ D, assuming 3/4″ thick box material (If you are using 5/8″ thick materials, you should subtract 1/4″ from each dimension). A slot port is recommended with the following dimensions:
Slot Width: 1.5″
Slot Height: 12.0″
Slot Length: 22.5″ (a right angled port with a 7.25″ extension)
