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 75 Watts, for best audio performance it is recommended to run an amplifier capable of between 175 - 250 Watts of continuous power per driver, like the JL Audio JX250/1 or JL Audio XD300/1v2. In addition, these subwoofers are optimized to operate in either a ported or sealed enclosure, needing only 0.30 cubic feet of air space in a sealed box and 0.35 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'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 airflow, 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.

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.

Great Sub

Have 2 of these underneath the backseat in a F-150 2010 extended cab. Great sub hits the notes very LOUD!!! Great sub for having no space to put them. Have it setup w/ JL audio to get rid of factory speakers and you can hear every note high and low. Worth the buy. May be worried about not getting the bass you want. DON'T worry about that at all. Get a great box too and they work superb.

I purchased these subs and I'm very pleased with them.

JL Audio makes a good product. I have made many buys from Sonic, very pleased.

Very Solid

I am very pleased with these subs. I have 2 of these in my 03' f150 supercrew and these fit under my backseat perfectly without any real modifications. my amp is a Alpine MRP-f300
SOUND: these subs really do sound great. They have what i would call "grown man bass." Your probably not going to shake your neigbors cars mirrors but they provide a very solid thump without being flooded or sloppy. I have always had 2 12's in all my previous cars and while these don't hit as hard as those did on the very deep lows they still hit amd I would say it is rather close and these sound better.
SIDE NOTE: As always it depends on what amp and whatnot you have running your speakers but with these i can set loose change on my console and watch it move with the bass where i have never really been able to do that before even with my 12's
CONCLUSION: if you are a teen and just what the most flooded. ratteling bass you can find these might not be for you. but if you want a very clean sound that will still shake your seat and fit conveniently in a tight space i would highly reccomend. .
*Only giving 4 stars for look/design and durability as i never see speakers and have only had them for 6 months so can't fully speak to durability.

I put a single 8W3 in a fiberglass enclosure in the back of my SUV on 240 watts. It really gets down! Best in a sealed enclosure.

sound supreme ++

i have a lexus sc 400 these speakers with components and all fit flawlessly and offer a sound that is truly extraordinary, i was advised to buy this brand with guaranteed satisfaction, and i openly admit that is what i have. Complete satisfaction and super pounding power, highly recommended, state of the art is JL Audio, and i got a 8 inch sub instead of 10 i was very worried it would not provide the bass i wanted wow it vibrates the mirrors and seats and thumps!! more than expected and surpassed 2 friends 10 and 12s they had

8" W3?

These really do not sound like 8's. They slap hard and people are always amazed when they hear them. I have 2 8 W3 in a sealed box in a nissan frontier crew cab and they hit so hard. I had someone come into my car not knowing i had subs and asked them what they sounded like and he said he thought it was a 12 in a large box. No one believes they are only 8's until they see them. I definitely recommend this to anyone limited in space and wanting the most boom for their buck

Super 8

2008 Wrangler Unlimited. Made spacer so that the 8w3v fits in OEM enclosure. Being fed by Cadence XAH250.2 mono. If you are reading the reviews, you know the praise for this little thing. No BS, this little thing is awesome for an 8. In previous vehicles, I've had a single 10 and a single 12. Both Polk db's. The JL is as loud as the 10 and musically it sounds better than both the 10 and 12. Both db's sounded "messy". This one is very precise. Definitely worth they extra money and for this particular application, it is perfect.
