JL Audio W3v3 Series Subwoofer Driver
JL Audio W3v3 Series Subwoofer Driver

Easily the best selling subwoofer driver, next to the W6v3, the JL Audio W3v3 provides phenomenal performance at moderate power levels with superb sound quality. The W3 series is in its 3rd iteration, embodying the series' pursuit for providing outstanding output and world-class sound quality. This is accomplished by utilizing a whole suite of advanced technologies originally developed for JL Audio's flagship W7. An Elevated Frame Cooling design helps in delivering enhanced power handling and sound quality. The DMA-optimized, long linear excursion capability minimizes distortion and increases output, while multiple patented technologies enhance performance and reliability. Such advances make the v3's the best sounding, most reliable W3's yet.

Although the W3v3 Subwoofer can be driven with as little as 150 Watts, for best audio performance it is recommended to run an amplifier capable of between 300 - 500 Watts of continuous power per driver, like the JL Audio XD600/1v2. In addition, these subwoofers are optimized to operate in either a ported or sealed enclosure, needing only 1.125 cubic feet of air space in a sealed box and 1.75 cubic feet in a ported/vented enclosure. (Specific dimensions and figures can be found in the user manual, linked further below.)

Like many other high quality JL Audio products, all W3v3 subwoofers are built in JL Audio's Miramar, Florida factory, with extreme precision and top-notch build quality. Its this attention to detail that delivers the JL Audio quality and performance we have all become accustomed to.

JL Audio Patented Cooling Technology

JL Audio Patented Cooling Technology

JL Audio's patented Elevated Frame Cooling design delivers cool air into the heart of the subwoofer in ways no other manufacture's driver can. Purpose-engineered slots located directly above the top-plate stream air to the voice coil. In addition, the upper surface of the top-plate is directly exposed to this air flow, whereas on a conventional design it is isolated from this flow by the lower flange of the frame. This technology not only increases thermal power handling, but also sound quality by minimizing dynamic parameter shifts and power compression. In plain English, this driver keeps itself cool so you can play your system longer, safer and without having to worry about frying the motor.

Extraordinary Linearity and Control

Tight, Clean, Articulate Bass

DMA is JL Audio's proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 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 vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. Its main catalyst is the driver's Ultra-long Voice Coil, that allows extreme linear excursion, phenomenal power handling and control, control, control.

The best subs I've owned.

The following review is for 12W3v3-4, which is a part of the bundle you are viewing.

I don't have these ones I have a pair of 12W3v2-4 that I bought from a pawn shop for $100 two years ago. I have them in a ported box powered by a 1100 watt class d Sony Xplod and they pound. Now if the sub doesn't say JL on it I won't buy it.

Deep, Clean, Kickin' subwoofer!

The following review is for 12W3v3-4, which is a part of the bundle you are viewing.

Alright now when I go to reviews, I want to know the variables (car make, box type, box size, etc.). Before I go any further this subwoofer is wonderful and a pleasure to listen to. Now i shall explain WHY it's a great woofer. First off the variables: I have 2 of these subs wired to 2 ohms to an Audioque 1200.1D (both subs are getting about 450ish watts rms, and I don't even know if it's even that because my gain is turned down a bit) in a ported box, one slot in the middle. I don't know the specs on the box exactly, but i do know that the box size and port size are selling the subs short. EVEN with a prefab ported box, these hit accurately, clean, pretty deep, and they don't flutter or boom too much. I have my subsonic on to try and decrease that. Have in mind guys I'm a guy that likes his metal, rock, and music with a kick drum. Hear me out! these subs play any type of music accurately, and that's in a PORTED box. That alone is remarkable to me. And it's a cruddy ported box too! lol. Get these subs! buy them, hug them, love them, whatever you gotta do. Also if you can, get a custom built ported box and get ready to be blown away. These kick. Now for some physical characteristics of the car. I just got them tonight so i haven't observed much but i do know that my rearview mirror is absolutely useless. when i try and readjust it, goes right back down within 3 seconds. I drive a BUICK REGAL year 2000 for your information. I know i packed a lot of info in this review, but i'm very picky, hard to please in certain areas. So being a reviewer, I want to give a review that I'd want to see. As a multi-instrument musician, audiophile, bass lover, and just an average guy trying to have some summer fun with a good set of subs, these are now my go to subs. I've owned or heard sets of Diamond D3 12, Audiopipe TXX-be12, Kicker CVR 12, Power Acoustik Fubar 12, Rockford Fosgate T1 12 (that was a single), 3 Image Dynamic 12s v2, Rockford Fosgate P2 12, Sundown E Series 12, Powerbass L12, Kicker Comp, Kicker L7 15 (single), and probably more that I can't think of, but these give every sub set a run for their money! And beat out 90% of the subs I've heard (majority of them are listed above). Just goes to show you don't need a set of 1000 watt rms subs to bump, you just need a set of these ;) Hopefully this helped. Take Care!

Quality product

The following review is for 12W3v3-4, which is a part of the bundle you are viewing.

I have had this sub for around 2 months now and i freaking love it. This sub hits so hard and is so loud. The sub is in a 12" slot port box. the box's volume is 1.8 and it is super deep in sound and hits every note. I have a friend with a type-r running at 1ohm and 1400rms and this sub is just as loud running at 4ohms and 500rms.

Best deal on the market

The following review is for 12W3v3-4, which is a part of the bundle you are viewing.

I have tried a lot of subs over the last 5-6 years since beginning to enjoy car audio. Some of the names I have used include Infinity Reference and Kappa, Sony GTR, Alpine Type R, Memphis M-Class and reference, and Kenwood Excelon. These are easily the BEST SQ sub for your money, and among the top subs on the market period. They are not going to make you an SPL champion, but they provide more than adequate low-end punch when powered properly.


* Awesome quality - right off the bat you can see the time and effort JL puts into their products. Fit and finish is superb, and the clean look of the cone just made me fall in love. Installed in a box with black carpet and it is the stealthiest, sleekest looking thing you'll ever see.

* Superior SQ - the most accurate sub of any I have ever owned. Have a single 12w3 in a 1.3CI selaed box running off a Hifonics BRZ1200.1D (450 RMS output, 50W under RMS) and it does not miss anything. Nearly perfect bass reproduction in all varieties of music (I listen to anything from dubstep, to classic rock, to blues - very eclectic music style and this sub handles it).

*Untouchable value - you will not get quality and SQ like this anywhere else for 180 bucks. Period.


*Not as loud as some others - to me, this is not a con. If you know what you are buying, this isn't an issue. This is made to be an SQ sub, and to me the SPL is absolutely adequate. Don't fool yourself, the w3 gets LOW, but it is not going to flex your trunk really hard or crack windows. In my hatchback, it rattles all of my mirrors as well as any change in the center console when turned up. It has even loosened the bolts inside my door skins that hold the hand rests to the door to the point I will need to take the doors apart and tighten them.

To sum it up, BUY THESE. A product doesn't get 4.9 stars on 39 reviews for no reason. Put the right amp on this product and you'll have a system that anyone from a complete beginner to a seasoned audio pro can appreciate. I have mine slightly under powered, in a sealed box and it is so amazing I wouldn't even bother with anything else. I never thought to try one until I heard them at a local shop and decided to research them a little more. Just as an estimation, I could probably give this sub 100-150 more watts and I think it would handle it perfectly fine.

JL has COMPLETELY outdone themselves, and this is far and away one of the top values in car audio history. No vehicle I own from now on will have anything but JL W3's in it.

tremendous sound

The following review is for 12W3v3-4, which is a part of the bundle you are viewing.

I have just one of these in a crappy looking box so people just laugh when they see it in my trunk. When i turn it on, i get cash offers on the spot. AMAZING for all types of music. If you can find them used, grab them, otherwise the price isnt too bad on them anymore.

Good sub

The following review is for 12W3v3-4, which is a part of the bundle you are viewing.

Had two of these in a ported box and they hit hard. They cant really handle the real low bass notes but for all other ranges they handle it perfect. These subs can take a lot of power so hook them up to a big amp.
