Enclosure: The ProWedge sealed enclosure is optimized for the
10" W7AE-3 subwoofer and built from 1" MDF. It's finished in high-grade
black carpet with a gloss-black laminate front baffle trim featuring engraved "JL
Audio" and "W7" logos. Three solid, brushed aluminum rods provide stylish woofer
Terminal: The enclosure features a pair of gold plated 5-way
binding posts on the left side. They will accept pin connectors, spade connectors,
single banana plugs, dual banana plugs, and bare up to 10 gauge.
- Width: 17.625"
- Height: 14.625"
- Depth (including grille): 18.625"
- Depth (top of enclosure): 11.5"
- Depth (bottom of enclosure): 16.75"
W-Cone: The JL Audio 10W7AE-3 subwoofer utilizes a W-Cone
design, a unit-body cone assembly, that delivers astonishing cone stiffness with
minimal mass. The shape also provides incredible torsional rigidity, which is
critical to maintaining voice coil alignment at the suspension limits. In order
to gain maximum stiffness, 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 provides incredible rigidity
when bonded to the dished upper skin.
OverRoll Surround: OverRoll Surround technology allows JL Audio
to make full use of the entire footprint of the speaker, placing the surround further
to the outside than in a conventional woofer. This means the 10W7AE-3 subwoofer can
use a large roll for all its benefits without sacrificing cone area. By maximizing
the effective piston/total footprint ratio, the subwoofer can deliver more output
for a given excursion and outside frame diameter. This means that the prodigious
excursion advantage of the 10W7AE-3 can be put to full use enhancing output,
rather than making up for lost piston area. This technology also provides a geometry
advantage on the outside edge of the surround roll, allowing for more linear operation.
A further benefit is that the mounting holes are inherently sealed by the surround,
resulting in an improved box seal.
Ultra-Long Voice Coil: The 10W7AE-3 subwoofer features an
ultra-long voice coil to allow extreme linear excursion, phenomenal power handling
and control. The massive surface area of these coils is excellent for heat
dissipation, while the huge winding height provides the necessary motivational
force to achieve the huge excursion of the design. Considering their size, the
10W7AE-3 voice coils are extremely light in weight. The voice coil uses
aluminum-alloy wire (instead of conventional copper) and a specific winding
method to achieve JL Audio's desired electrical properties. The light weight of
the coils helps keep the overall moving mass down at manageable levels, which is
extremely important for efficiency and sound quality reasons.
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 method of improving dynamic motor behavior. As a
result of DMA optimization, the 10W7AE-3 motor force remains linear over a very
long range of excursion. It also maintains a stable fixed magnetic field
in the gap over a wide power range. The result is vastly reduced distortion,
faithfully reproduced transients, and tight, clean, articulate bass.
Forced Air Cooled: The elevated
frame design of the 10W7AE-3 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
Radial Cross-Drilled Pole Piece: This
innovative venting system enhances thermal dissipation and power
handling by directing air flow onto the voice coil former and works 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.
Progressive-Roll Spider: The large,
progressive-roll spider provides precise control and motor/voice coil alignment
without limiting excursion prematurely.
Plateau-Reinforced Spider Attachment: The
lower reinforcement collar, attached to the voice coil former of the W7,
incorporates a plateau design dedicated to relieving material stress and
providing a solid attachment surface for the inner edge of the spider. The
plateau of the reinforcement collar provides excellent contact area for adhesive
therefore creating an incredibly strong bond at a critical point within the
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.
