Our take on the JL Audio CS112G-W6v3

by Bob Bihlmayer
JL Audio

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.

Great bass without the loss of space

It may look like something from a sci-fi movie, but JL Audio's CS112G-W6v3 12” sub enclosure is actually a design marvel. JL nestled their W6v3 12” subwoofer into a sealed enclosure that takes up less room than conventional 12" subwoofer boxes. This sub handles up to 600 watts RMS so it'll deliver that fat low end you want, while its 2-ohm impedance makes it a perfect match for a mono amplifier.

One tough sub enclosure

While they may have cut the corners on the medium density fiberboard (MDF) enclosure, JL didn't cut corners on quality. They incorporated their V-Groove™ construction to ensure rigid box joints that won't leak air or resonate. Combined with the slim sub, this new design gives you a sturdy sub box that doesn't take all your cargo space. JL finished off this ProWedge enclosure with a tough polymer grille that protects the entire subwoofer, unique for an enclosed subwoofer design.

  • sealed enclosure with one 12" W6v3 subwoofer
  • medium density fiberboard construction covered with black carpet

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Enclosure: The enclosure is sealed and houses a single 12W6v3-D4 12" dual voice coil subwoofer. The dual 4Ω voice coils are internally wired in parallel to present a 2Ω load. The MDF enclosure is finished with black automotive grade carpet. A tough polymer grille protects the subwoofer.

Terminal: The enclosure features a pair of 5-way binding posts on the back. The posts will accept pin connectors, spade connectors, single banana plugs, dual banana plugs (standard 3/4" width), and bare wire up to 10 gauge.

Enclosure Dimensions:

  • Width: 14-3/8"
  • Height: 16-5/16"
  • Depth: 13-3/4" (including the grille, just the enclosure is approximately 13-1/4" deep)

Subwoofer Technology:

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 12W6v3-D4 motor remains linear over a long excursion range, and also maintains a stable fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
  • Pole-Vent Airflow Control (PVAC): The bullet-shaped structure inside the pole-vent directs airflow and increases air velocity to effectively reduce voice coil temperature, leading to improved fidelity and reliability.
  • 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.
  • Elevated Frame Cooling System: The elevated frame design of the 12W6v3-D4 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.
  • Engineered Lead Wire System: JL Audio's engineered flying lead-wires have carefully designed entry and exit support structures molded into the terminals and the voice coil collar. They are jacketed to further reduce the likelihood of shorting and fatigue. The result is predictable high-excursion lead-wire behavior with long term reliability, and none of the compromises inherent to a woven-in lead wire system (when attached or woven into the spider material, lead-wires can alter the spider's motion, leading to asymmetrical spider behavior).
