JL Audio's top-of-the-line subwoofer
JL Audio's top-of-the-line subwoofer
JL Audio's 30-plus years of research into car audio design has produced the legendary W7 subwoofer, and you'll hear that engineering in every note. JL Audio applies its advanced technologies separately to each W7 subwoofer, so each size sub is a unique design with its own motor and suspension system. You'll hear smooth, audiophile-quality bass output, even at extreme levels.
Advanced technology for superior sound
W7 subs feature six different patented technologies which give them their edge:
- W-Cone: a dish-shaped outer cone is supported by a second W-shaped inner cone attached to the the sub's voice coil structure. The light mineral-filled polypropylene cones respond rapidly for accurate, distortion-free bass without unwanted coloration.
- OverRoll: the oversized polyether foam surround extends over the edge of the mounting flange for more bass output without sacrificing linearity.
- Floating Cone Attach Method (FCAM): cone-bonding technology keeps the voice coil centered during long excursion.
- Plateau-reinforced spider attachment: a collar on the voice coil eases stress on the spider for extended excursion and improved reliability.
- Elevated frame cooling and cross-drilled pole-piece: cone movement pumps air through vents in the frame and machined holes in the pole piece, keeping the voice coil cool.
Reliable performance and accurate response
JL Audio designed the 3-ohm 10" W7 subwoofer to maintain linear motion during extreme cone travel, so you get a high-performance sub that's incredibly reliable. You'll find a strong cast-alloy basket and ultra-long voice coil among many impressive features which help this sub deliver profound, natural, and lifelike bass. This 3-ohm sub should behave similarly to a 4-ohm subwoofer in most power applications; call 1-888-955-6000 if you have further questions on powering your W7 system.

W-Cone: The JL Audio W7 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 that W7 subwoofer can use a large roll for all its benefits without sacrificing cone area. By maximizing the effective piston/total footprint ratio, the W7 subwoofer can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 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 W7 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 W7 designs. Considering their size, the W7 voice coils are extremely light in weight. The W7 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 aimed at improving dynamic motor behavior. As a result of DMA optimization, W7 motors remain linear in motor force over a very long range of excursion, and also maintain a highly 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.
Massive Forced Air Cooled: The elevated frame design of the W7 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.
Radial Cross-Drilled Pole Piece: This innovative venting system greatly 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 driver.
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.
Recommended Sealed Box Volume: The sealed box size recommended by JL Audio is 1.25 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 15.5" W x 14" H x 15" D, assuming 3/4" thick material for the top, bottom and sides of the box and 1" thick material for the front baffle board. (If you are using 5/8" thick materials, you should subtract 1/4" from each dimension.)
Recommended Ported Box Volume: The ported box size recommended by JL Audio is 1.5 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 23.375" W x 13.5" H x 14.5" D, assuming 3/4" thick material for the top, bottom and sides of the box and 1" thick material for the front baffle board. (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)
