JL Audio's ProWedge enclosure provides the ideal home for their W7 Anniversary Edition subwoofer, a hand-assembled sealed housing that allows the sub to produce bass notes with impressive depth, detail and clarity. This versatile sub will enhance the impact of any type of music, from the subtle thrum of the stand-up bass in a jazz ensemble, to the satisfying gut punch of a rock band's kick drum.

The W7AE ProWedge features a unbelievably rigid sealed enclosure, made from solid 1" thick medium-density fiberboard and optimized for the W7AE subwoofer. The glossy black laminate baffle with its embossed logos adds a touch of class, while the durable black carpet covering keeps nicks and scratches at bay. Three stylish brushed aluminum rods protect the woofer so it can deliver long-lasting bass in your vehicle. Gold-plated, five-way binding posts allow for convenient and secure hookup.

The CLS112RG-W7AE enclosure contains one 12" W7AE subwoofer, creating premium bass with the help of six patented features and a computer-optimized motor assembly design.

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Enclosure Features

Enclosure: The ProWedge sealed enclosure is optimized for the 12" W7AE subwoofer and built from 1" MDF. The enclosure (and sub) weighs just under 82 pounds. It's finished in high-grade black carpet with a gloss-black laminate front baffle featuring engraved JL Audio and W7AE logos. Three solid, brushed aluminum rods protect the woofer cone.

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.

Enclosure Dimensions:

  • Width: 21-3/8"
  • Height: 16-5/8"
  • Depth (including grille): 19-1/8"
  • Depth (top of enclosure): 11-1/4"
  • Depth (bottom of enclosure): 16-5/8"

Driver Features

W-Cone: The JL Audio W7AE subwoofer utilizes a W-Cone design, a unit-body cone assembly, that maximizes cone stiffness with minimal mass. The shape also provides torsional rigidity, 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 of the frame than in a conventional woofer. This means that W7AE subwoofer can use a large roll for all its benefits without sacrificing cone area. By maximizing the effective piston/total footprint ratio, the W7AE subwoofer can deliver more output for a given excursion and outside frame diameter. This means the excursion advantage of the W7AE 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 W7AE subwoofer features an ultra-long voice coil to allow extreme linear excursion, phenomenal power handling and control. The 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 W7AE designs. Considering their size, the W7AE voice coils are extremely light weight. The W7AE 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, W7AE 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.

Forced Air Cooled: The elevated frame design of the W7AE 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 W7AE, 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.

I've owned a lot of subwoofers over the years, but I will have to say, this is the best one yet. Rock solid construction, American made (yep, built in FL), very loud and accurate. Not that "boomy" bass you get from a vented/ported enclosure. I listen to a very broad range of music, not a lot of rap, but like to hear the punch or kick of a tight bass drum, and you'll definitely hear it with this W7. Jazz and R&B music lovers-this is the sub for you. First, I wanted a top quality sub that would fit in the trunk of my 2011 Honda Accord coupe. It's a perfect fit and it doesn't take up as much trunk space as I though it would. Believe it or not, I'm powering this beast with an Alpine PDX-V9 5 channel amplifier. You're probably saying, what?? This little amp actually may be underated for the subwoofer power output. It pushes this 12" W7 flawlessly. The guys at the Crutchfield Charlottesville retail store were amazed after they helped me load it in the trunk and I connected the speaker wire. I'm sure this sub will play as loud as how much power you can throw at it, and granted I'm not trying to rattle the entire car or need people to hear me approaching from 4 blocks away. Anyway, to sum it all up, a great product from JL Audio and I'm very, very happy with it.

Pros: Tight, accurate bass, superior build quality, JL Audio W7 reputation.

Cons: A little bit on the pricey side-but you get what you pay for! VERY heavy-be sure your trunk floor will be able to support it.

Get everything you’ll need to enjoy your new JL Audio CLS112RG-W7AE

It's critical to have good wire, and none is included with the sub.
