JL Audio W1v3 Series Subwoofer Driver
JL Audio W1v3 Series Subwoofer Driver

The W1v3 is an outstanding choice when your build provides space that is very tight and amplifier power that is respectably moderate. The driver features a shallow mounting depth (5.41 in. / 137 mm) and a compact motor structure, allowing it to comfortably fit in a lot of spaces where a typical 12-inch driver will not. Lacking a pole vent, the rear of the motor structure can be placed directly against an enclosure boundary. In addition, excellent excursion capability and linearity allow it to reproduce sub-bass with striking extension and quality. Several of JL Audio's proprietary technologies enhance its performance and reliability. This includes JL Audio's patented DMA, Elevated Frame-Cooling and Floating Cone Attach Method™ technologies.

Dynamic JL Audio Performance

Dynamic JL Audio Performance

The 12W1v3 Subwoofer can be driven with as little as 75 Watts. However, for best audio performance it is recommended to run an amplifier capable of between 200 - 300 Watts of continuous power per driver, like the JL Audio JX500/1D. In addition, these subwoofers are optimized to operate in either a ported or sealed enclosure, needing only 1.10 cubic feet of air space in a sealed box and 1.60 cubic feet in a ported/vented enclosure. (Specific dimensions and figures can be found in the user manual, linked further below.)


Striking Linearity and Control

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, W1v3 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.

Very pleased!

If you’re looking for something that’ll fit in a smaller, under seat box…this is it. They’re not the cheapest, but there’s more expensive out there too. Do it…you won’t be disappointed

I’ve always had 12’s, but wanted to go with something that would fit better in my truck, so I got some kicker 10’s. After some time with them, I just couldn’t get down with the 10’s….they just don’t do what 12’s do. After doing some digging, I found these W1’s worked for the same airspace as the box I have for the 10’s (they ask for 1 sq ft and the box is about .95 per side) and the amp (kicker 800.1) I have as well. Hooked them up today, SUPER excited with the result. Obviously I haven’t had much time on them yet, but I can already tell I made the right decision. I haven’t even really turned them up much and the bass is on point. I still need to re-tune the amp since putting them in. Need to make some adjustments tomorrow, but it’s jammin nice now.

WOW

The following review is for a previous version (12W1v2-4).

I would definitely recommend these speakers to people. I have to 12"s in these subs, with the JL PowerWedge box. I'm using these subs with a JL 500/1 amp,but at 2 ohms its only putting around 275watts RMS. THEY POUND in my camaro. I was very supprised with these subs. I love JL audio. They have never let me down. Great subs for the amount of power they only need to take. I've owned Kicker CVR's, L7's, Comp's and many others. these are good subs.

You have one 12???

The following review is for a previous version (12W1v2-4).

I have this sub in a huge 2.5 cubic feet vented box tuned at 50hz. I'm running a 600w (300rms) amp at 4 ohms to it and this thing is literally an eyeball rattler. If I'm in my driveway and I have it turned up the windows on my house shake and so does the china cabinet. It hits the lows like they are nothing while still providing superior sound quality. This thing is rediculous. Only con is the color. It is an ugly grey color. But jl gives you a metal grill to go over it which hides it.

Compared to the w0 series the w1 demolishes it. It is worth the upgrade. A friends car had 2 12" w0v2s in a vented box and you could only feel the bass. There wasn't much sound to it. But my single 12" w1v2 blew it out of the park.

sweet

The following review is for a previous version (12W1v2-4).

These speakers are awesome!! They seem to handle any power with ease. I put them in a ported box and the bass hits real hard which was something I did not expect. I totally recommend this speaker to anyone..

Good sub just dont put true power to it

The following review is for a previous version (12W1v2-4).

Blew one out on the first day of use. Don't put the "TRUE" RMS rated power through these. I think they expect you to be using one of those cheap amps that claims to make this power but really makes less. It is a good sub for boxes that don't have much back spacing, like in a truck. Just keep the power low on these suckers.
