JL quality at a great price

JL Audio built the BassWedge CP112-W0v3 enclosure to make car-rattling bass for a reasonable price, without the need for a ton of power. The enclosure's designed to match the 12" sub loaded into it, so you know you'll get every ounce of performance out of this enclosure.

BassWedge CP112-W0v3 enclosure

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.

The enclosure is finished and inspected by hand at the manufacturing facility in Florida to ensure that you get the bass that you expect from 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.

Product Research

Features

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.

I love this woofer. It doesnt take up much space, looks great, and can play low and loud. Match it with the JX500/1D!

Pros: Great Sound, Power Handling, Clarity, and Design.

Cons: It doesn't come with an included speaker grill.

Boooom box!

Lets get the obvious out of the way: I'm older. I'm not a kid so I shopped and shopped and compared different boxes and different amps with an idea of what I wanted and ended up purchasing this. I made an incorrect assumption that being a JL audio subwoofer, I would have a musically accurate subwoofer. This sub is for people who want to be loud. It has a very specific hz range that it is dramatically louder than the other lower notes. It is a very high quality sub. It has a much drier sound to it than other ported boxes but the "ported box" feel is still very much there. For example, the resonation of prolonged notes is heard but not felt. It hurts your ears but you don't get the shake you would expect. It does look great and if you do listen to rap or R&B, you will probably love this sub. I have a MTX Thunder 500d(300w @ 4ohms) amp powering this sub and only have the gain up 2/3 with none of the "bass boost" on at all. It is very loud. It is capable of playing any genre of music with satisfying results. Double bass drum rifts do not get muddled together and sound like one continuous note. Bottom line being: know that if you want to hear a song as the producer intended, this subwoofer will not satisfy that need. If that doesn't bother you, buy, buy, buy, because this sub is very loud and looks much better in person than the pictures show.

Pros: Very loud, tight for a ported box, looks great!

Cons: Not musically accurate. Has a limited HZ range that is twice or three times as loud as the other notes.

This is an awesome ported sub, sound quality is what you would expect from JL Audio, if I had the space I would have purchased two of these subs!

Pros: Sound quality from a proven company! You truly get what you pay for..

Cons: It's a little large, with the given dimensions, it seems larger and it does take up some space.

I just received this sub and have it on the back seat of my 2007 Dodge Ram 2500, I have a Pioneer AVH-4400BT Head Unit, my Amp is a Kenwood 8105D 300W @4ohm and 500W @2ohm. I did have a under seat 10" Rockford sub in a small sealed enclosure. This JL is a perfect fit for the kenwood amp, JL is known for building "SQ" Sound Quality Subs, this thing sounds amazing, I listen to Heavy Metal and Thrash Metal with lots of kick drums and I am so glad to finally have a JL sub again. I don't think that you could find anything better for the price, and of course the peace of mind with CrutchFields return policy. If you are looking for a killer 12" SQ Sub that wont break the bank then look no further. And for those of you wondering yes this thing does boom. Also a plus is this enclosure is designed by JL to fit the sub which is 1.75 cu ft which is the same requirements as the 12" W3V3 JL sub if you want to do an upgrade in the future. Thanks Crutchfield!!!!

Pros: Great Price, Awesome Sound Quality and good looks.

Cons: None

It's critical to have good wire, and none is included with the sub.
Dynamat helps reduce ambient road noise and your vehicle's "rattles," making it easier for you to hear your music better. Easy to install.
Add a grille and keep your sub safe.

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 ]
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Krissy  Aug 11, 2014 ]  Staff
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 ]
