JL quality at a great price

JL Audio built the BassWedge CP212-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 two 12" subs loaded into it, so you know you'll get every ounce of performance out of this enclosure.

An excellent combination

The CP212-W0v3 BassWedge contains two 12" W0v3 subwoofers that handle up to 600 watts RMS, and are loaded into a specially built slot-ported enclosure. The enclosure can be placed with the woofers firing downwards, or in typical front or rear firing applications, giving you immense bass regardless of how you place it.

Solid MDF enclosure

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure with rugged automotive carpeting, nickel-plated push terminals, and solid internal wiring. 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.

Features

Overview: The JL Audio slot-ported BassWedge subwoofer enclosure is designed around two of JL Audio's 12" W0v3-4 (4Ω) subwoofers. 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 grilles (item number 136SGR1231, sold separately and individually) can be added to protect the woofer cones.

Dimensions: The CP212-W0v3 enclosure isn't symmetrical; it's approximately 31-5/8" wide, 15-1/4" tall at its tallest point (toward the front), 12-7/8" tall at its shorted point (toward the back), 20-5/8" deep at the base, and 16-5/8" deep at the top.

JL Always Impresses

I've always been a fan of JL Audio subs and amps and this box of 12s does not disappoint. I've always built my boxes before, but this factory built box has been a great experience. I will definitely buy JL Audio again in the future.

Pros: Amazing bass and appearance

Cons: The box is kinda big and isn't custom built for the car, but the the front and back angled edges definitely fit against the rear seat better than expected, which saved some room. All in all it is a lot of bass for the amount of space it takes up and I still have enough of a trunk left for golf clubs and groceries... Also, doesn't come with the speaker grilles but I bought them at the same time and all was good.

Nice subs

I always hated seeing reviews of items that people have had for only a month, but here I am doing the same thing. I've had these about a month, and they bump real hard. I upgraded from the less expensive version of these and there is a noticeable difference. These hit the lows and highs much better and can handle a lot more watts than my other subs that I had. If you're also looking at the less expensive WXv2's, I suggest you go with these because they sound much better. Just for a little more money it makes a huge difference in sound quality. Make sure you have an amp that can power these to their full potential. These are two ohm subwoofers so getting an amp with around 500 Watts RMS at two ohms will be just fine. I'll try to update this if I find any problems with them.

Pros: Size, Watt Handling, Style, Power, Wide Range of Bass.

Cons: Expensive but that's the price you pay for quality.

This is by far the best sub enclosure that I've purchased yet. JL Audio subs & amps are some the best products offered in the mobile audio industry today. I'm very pleased.

Pros: Sounds excellent any way you place it.

Cons: No speaker grilles.

These subs blew away my expectations. I turned up the gain on these from my amp and my trunk rattles like a chainsaw. My windshield wipers actually rattle also, and my rear view mirror is useless at times. I was upgrading from one 12" sub and these sound way louder then I thought they would! Impressed.

Pros: Nice sound, great quality enclosure

Cons: A little on the expensive side, but worth it!

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

I forwarded your question to an Advisor and they responded with the following: Each sub has a 4-ohm impedance and they are wired in parallel to have a total box impedance of 2-ohms. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Oct 07, 2014 ]  Staff
Ported is always louder than sealed in my opinion. I think you would gain a lot since you would be doubling your output with two subs and swithing to a ported enclosure. If your rear seats fold down then it will work well, I could be heard from a good distance, set off an alarm or two and had many people roll up windows in traffic when next to me lol. I enjoyed every minute with these, slight trunk flex too [ IVAN A  Aug 13, 2014 ]
