JL Audio CP212-W0v3 Loaded Sub Enclosure

JL Audio's dual 12" slot-ported loaded BassWedge subwoofer enclosure has a peak power rating of 1200 watts and an RMS rating of 600 watts. The enclosure is loaded and wired with two JL Audio 12W0v3 single 4-ohm subwoofers. The W0v3 offers superb excursion capability, linearity and an overall performance output that puts it right at the top of its price class. The driver features a very beefy 2.0-inch diameter voice coil, a DMA-optimized motor system and JL Audio's patented Elevated Frame Cooling design - all purpose-engineered for enhanced power handling and reliability. What this also means, is your system will be immediately injected with the increase in output and better sound fidelity that one expects from a JL Audio product. In addition, excellent excursion capability and linearity allow it to reproduce sub-bass with striking extension and quality. When matched up with the proper power source, signal and setup the W0v3 is capable of a well rounded sound that is unparalleled by any other driver in its price range.

Flexible JL Audio Power

The CP212-W0v3 Enclosure can be driven with as little as 150 Watts. However, for best audio performance it is recommended to run an amplifier capable of between 400 - 600 Watts of continuous power per driver, like the JL Audio XD600/1v2 or JL Audio JX500/1D. In addition, The ultra-versatile BassWedge shape has extended sides so that it can be placed with the woofers firing out or straight down, off the floor of the vehicle. The shape works equally well in forward or rear-firing installations. This gives you plenty of options for tweaking the loading of the enclosure into your vehicle.

Striking Linearity and Control

DMA is JL Audio’s proprietary Dynamic Motor Analysis system and is aimed at delivering superior dynamic stability and low distortion. As a result of DMA optimization, W0v3 motors remain linear in motor force over an extreme range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to tight, clean, articulate bass that also allows for extreme linear excursion, phenomenal power handling and control, control, control.

"Boom for your buck."

After owning three different kicker subs, all 12s, i decided to go with JL and invest in these two tens. I'm pleasantly surprised with the quality of sound. I'm getting out of these two tens. Deffs going to be sicking with JL audio from now on. These hit HARD for their size. I recommended these to my friends and they have the same views as i. Great product.

Great Subwoofers, Great enclosure

I have mine on a 4000 watt ssl amp
that pushes 2000 watts true so 1000 on each
they slam hard in the back of my xterra
the enclosure is very versatile for how you want to set it up
i have had a few systems and installed many ide say the
audio quality is very high, and they way they sound in my car i feel like a ROCKFORD FOSGATE amp would be the best thing on these

Went from a single 12" ported setup to this 2x 12" JL Audio ported box. The difference in air displacement 2 12's makes is exactly what I was looking for. A little bit of time to break them in and the lows this thing can generate are impressive. I've dynamat'd everything and only pushing it with 300w/rms (half power). All of my rear view mirrors are now useless with the volume up. I recommend it.

Just got 2 of these boys in a 05 neon and the box couldn't fit any better. It looks like it was profesionally built in to my trunk specs. Not to mention how great they sound. Any jl product is good and you won't be disappointed at all on this setup. Ill admit I was a little iffy about it at first but now I'm very pleased. Runnin with a 500 watt tma and it sounds amazing.

Love JL

Purchased this box from a local shop known the guys there since high school cut me a deal for 350$ on a new box. This is the 3rd JL product i've ever owned and the SQ is unbeatable. I bought Sundown and Skar subs on reviews stating they are better or the poor mans JLs and nope sorry just fast responding noise purely for the spl junkies. I'm grown i need to hit the lows and hear it not just trash my vehicle from vibrations. Although these are entry level bottom of the barrel from JL my mirrors shake like crazy, all the plastic in my interior vibrates and my upper console sunglass compartment pops open. This tiny box packs a hell of a punch in my suv, have them on a punch 1000bdx dyno'd @1501 watts @1ohm. This box is rated for 600 rms max total. My amp states 500 rms which it is probably more like 650+ @2ohms easy. Barely have a few hours in on the break in period and i'm like dam! Turned my gain down some from the shop tune felt like they were too crazy with it and they said you're good to go come back after 2 weeks and we will turn it up more lol. Doubt they can take more and after a hour of banging them tonight my amp was ice cold i may have to get another box JL just hit so clean. I just came from two NVX top of their line 1000 watt rms cea certified 15s ran them on the same amp full tilt till clipping and these sound better. They were nice subs worth every penny but i was ruined by the sound of JL.

Clean Deep Bass, Definitely happy with them overall

Had the ussual brand name subs throughout the years. Finally decided on this preloaded JL box a few years ago and have no regrets. If your thinking about it just buy it, clean sound and hits hard.
The box looks great and well built.
Powered by a kicker zx750.1 gain waay down.
