An excellent combination

The CP112-W0v3 BassWedge contains one 12" W0v3 subwoofer that handles up to 300 watts RMS, and is loaded into a specially built slot-ported enclosure. The enclosure can be placed with the woofer firing downwards, or in typical front or rear firing applications, giving you immense bass regardless of how you place it.

Fast shipping, sounds great.

Hands-on research

Product Research


Overview: The JL Audio slot-ported BassWedge subwoofer enclosure is designed around JL Audio's 12" W0v3-4 (4Ω) subwoofer. Aggressive tuning delivers powerful bass without the need for a huge amplifier. The MDF enclosure is covered with gray carpet and has JL AUDIO logos embroidered across the top and front. The enclosure design offers a variety of installation options: forward, rear or down firing. The slot-port runs along the bottom of the enclosure and fires on the same plane as the woofer; the port mouth is flared to minimize air-flow noises.

Speaker Terminal: The enclosure uses one pair of nickel-plated, high current spring posts. The posts are located on the left side of the box and will accept pin connectors, single or dual banana plugs, or bare wire up to 10 gauge.

W0v3 Woofer Features:

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 12W0v3-4 motor displays linear force over a long excursion range, and also maintains a stable fixed magnetic field in the gap over a wide power range. The result is a reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
  • Elevated Frame Cooling: The elevated frame design of the 12W0v3-4 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.
  • Rear Gasket: The woofer has a rear gasket to provide an optimal seal when installing into the enclosure.
  • Long Excursion: The subwoofer has an Xmax of 11.4mm, giving you louder bass with less distortion.

Optional Grille: The optional SGRU-12 grille (item number 136SGR1231, sold separately) can be added to protect the woofer cone.

Dimensions: The CP112-W0v3 enclosure isn't symmetrical; it's approximately 16-1/2" wide, 15-3/8" tall at its tallest point (toward the front), 13-1/8" tall at its shortest point (toward the back), 20-3/4" deep at the base, and 16-5/8" deep at the top.

Why did you buy this?

It got pretty decent reviews and seems to deliver the type of bass I am looking for. I listen to a lot of EDM and a ported box is just what the doctor ordered! [ Christopher  Mar 20, 2017 ]

2 questions already asked

JL Audio enclosures are patented designs that have been created and intended specifically for use with the JL Audio subwoofer that's loaded inside--so in this case it wouldn't be recommended to use the CP112-W0v3 with a W3v3 woofer; you'd get much better performance out of the HO112RG-W3v3 enclosure that comes preloaded with the W3v3 instead. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. I hope that helps! [ Larry  Dec 15, 2016 ]  Staff
It makes plenty of bass. Hits hard, sounds clear and deep. Pushing it with a punch 300x4. Completely wrong amp and it still makes my classmates jealous [ Michael  Aug 18, 2014 ]

Yes, though it does start to roll off a bit below 25hz. I'm running a 300 watt RMS Class D amp. Measured with a SPL meter (with corrections) with a Stereophile Audiophile Test CD. This sub in my Subaru is Nirvana. [ Tristan  Aug 10, 2014 ]
