Our take on the JL Audio 6W3v3-4

by Dominic Devito
JL Audio

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Remarkably realistic bass

JL Audio built their W3v3 subwoofers to deliver powerful, accurate bass with a medium-power amplifier. Their extensive motor assembly research resulted in a design that ensures smooth, precise cone movement at any power level. Exclusive cooling features shunt heat away from the sub's internal motor structure for long term durability and reduced distortion.

Well-rounded performance

JL Audio W3v3 interior

The 6W3v3-4 subwoofer boasts a 6.5" mineral-filled polypropylene cone with a distinctive metallic JL Audio medallion. A patented design eases the stress felt by the rubber surround during cone movement, for increased reliability and consistent bass output. The removable, customizable trim ring accepts optional JL Audio grilles, and can be painted to enhance your installation. This W3v3 sub works well in a sealed enclosure.

To drive this single subwoofer, we recommend a mono amplifier rated between 120 and 225 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Features

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.

Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Vented Reinforcement Collar (VRC): The Vented Reinforcement Collar is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weaknesses. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. the VRC also feature slots that facilitate air flow directly onto the voice coil windings to reduce thermal compression effects and enhances reliability.

Spider/Lead Wire Assembly: The W3v3 features a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. The spider is insert-molded into a composite carrier tray which also incorporates the terminal assembly and lead wire strain relief features for enhanced reliability and optimal alignment of parts. The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance.

Elevated Frame Cooling: The elevated frame design of the W3v3 delivers high-velocity air flow through slots directly above the top plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.

Surround Stress Relief: By creating a radiused feature on the edge of the cone, stress is relieved from the surround material at maximum forward excursion, resulting in longer life and more consistent surround behavior.

Customizable Trim Ring: The woofer comes with a removable ring made of black ABS plastic which can be painted to match the installation theme and create a personalized look. You can purchase optional grille mesh inserts which are specifically designed to fit into the inner diameter of the trim ring.

Enclosure Compatibility

Recommended Sealed Box Volume: The sealed box size recommended by JL Audio is 0.15 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 9" W x 9" H x 6.75" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, you should subtract 1/4" from each dimension.)

JL Audio 6.5" sub 6W3V3-4

Written By Randy Y, Brunswick, OH on Monday, April 02, 2012
Crutchfield Customer Review (What's this?)
 
I purchased this sub as a replacement for my factory sub in my 2003 Maruader. Crutchfield would not say if the sub would fit, or if modifications would be required. As it turned out, I had to modify the factory sub box by cutting 2-2" holes with my holesaw to allow for the larger magnet structure, and there was some plastic below the old factory sub that I simply broke off with some pliars. Once this was done, the sub bolted right up, and I reinstalled the box. This sub made a significant improvement in both sould quality and loudness. The sound is tight, clear, and not boomy, which was my fear. The factory sub box seems to work fine after these modfications. I should mention that my car has a 100 watt factory amp for the sub, and I am very pleased with the result. I recently replaced all four factory 5 X 7" speakers with Polk DXI coaxials, and the entire system sounds great with the factory head unit. I've only had this installed in my car for a few days, so I can't comment on long term performance or durability.
Pros:
This sub is built like a tank, with a huge magnet structure.
Cons:
Had to modify the factory sub box.

JL needs to work on build quality

Written By Corey, Slidell, la on Thursday, March 15, 2012
 
I purchased two of these and built a ported enclosure between the rear seats of my 1994 Honda Prelude. The enclosure is approximately 1cuft, tuned to 38hz. They're running on my SAZ-1000D @ 2 ohm. Yes, the amp is overkill. I've had them installed for about a month now, and there are a few things that need to be said about them. First, they reach reasonably low for a 6" subwoofer. They are in no way suitable for midbass duties. They're decently loud in the enclosure I've built, but I wouldn't recommend putting these little guys in a sealed box because they just don't have the cone area to do anything noteworthy. They have very good sound quality and transient response. However, I think JL could have done a better job with these. For instance, I've had to repair the speaker twice already. A week after first powering them up, the decorative parabolic dust cap on the front began to separate from the cone underneath and making a lot of noise. Not a big deal, just ordered some CA glue and put it back together. Two weeks after that, the dust cap underneath (the real, functional dust cap), had come loose and made even more noise, so I had to remove the decorative cap again to repair the speaker.

All in all, they're a good speaker for a tight space... just don't expect to beat the block down.
Pros:
-Modest bass for a tight space -Sound quality -The "wow" factor of having a little boom with only 6" speakers -They look nice. Pointless, I know. -They bottom out long before they cook in my enclosure
Cons:
-One of mine has broken twice. -Power hungry little guys -Expensive.

Wife's Toyota Sienna

Written By daddy, Saskatoon on Tuesday, March 22, 2011
 
I was very nervous about the size and power of this little guy, but it sounds great. The bass is very fast and tight, and it adds a lot of punch to my wife's minivan. My wife has been complaining about the base toyota system for years so I finally broke down and treated her. I placed a downfiring 6w3 in a custom box that fit between the consol and the dash. I installed JL 6.5" C3's in my front doors with tweets in the dash and powered this stuff with a JL XD400-4. I also replaced the factory head unit with a JVC unit and powered my rear factory speakers with it. One warning with this sub is to watch your box size, I originally had this thing in the minimum .15 sealed box as stated on the JL website. Not great so I increased the box size to .18 cubic feet and away it went. Awsome sub for its size.

JL Audio 6W3v3-4

Written By turbo C, southen cali on Friday, February 25, 2011
Crutchfield Customer Review (What's this?)
 
I drive a '93 Toyota MR2. if you anything about this car, you know that sapce is very limited. I upgraded my sub from a JL 6W0 to one of these. After instalation, and putting it through it's first run, it blew my mind and didn't burn a gaping whole in my wallet. I work construction, so I'm not the most experienced person when it comes down to the technical side of things but I have heard many diffierent sound systems and I like what I hear from mine.
The enclosure I mounted the Sub in occupies a space of a couple of cubic feet and did not take any additional space that had already previously been used for the stock woofer. it's' an overall excellent product for the price.

JL Audio 6W3v3-4

Written By Audiophile, Southern California on Saturday, September 11, 2010
Crutchfield Customer Review (What's this?)
 
I have been an audiophile who likes superior sound quality in my vehicles for the past 15 years and I have always been a JL Audio fan because of their superior sound quality. I was running 2 JL Audio 10's in my Toyota Tundra Crew max and decided to try out these 6W3's because I wanted to save a bit of space and get a tighter/cleaner mid-bass sound in my system.

I took out one of my 10's and replaced it with 2 of these 6W3's running at 150 watts RMS each. My low pass crossover is set at ~120Hz and my high pass crossover is set at 30Hz for these bad boys. I was skeptical that I would get the performance I desired from speakers this small; however, I was pleasantly surprised. I must say that these things perform so well that I have my 10" sub switched off most of the time.

One of my co-workers was so surprised at the performance of these little guys that he is planning to put 2 under his dash in the passenger footwell of his Toyota Tacoma (Yes, the box size required for these is that small).

I definitely recommend these to anyone looking to add good quality bass to their system, especially if you don't have much space in your vehicle to put larger subs.

JL Audio 6W3v3-4

Written By Anonymous, West Central, MN on Saturday, July 24, 2010
 
I bought one of these to mount in my Jeep Wrangler's factory location, I had to make some modifications to the factory box to make it work. When I got it running with a 150watts RMS from my MTX Thunder 202, I was amazed, now it's not 10" woofer, but for a factory location, it was amazing, louder and cleaner than most 8" woofers I have heard. I am very happy with my purchase and for it's size it is hard to beat.

This little guy rocks!

Written By James, Arkansas on Friday, June 26, 2009
Crutchfield Customer Review (What's this?)
 
Having recently bought a Porsche Boxster, I was very displeased with the factory system. I upgraded the head unit and door speakers with Crutchfield products, and it made great improvements in the quality of the sound, but it was still very deficient in the low end. A Boxster has NO room in the cabin for medium to large subs. The front trunk is well insulated and no sound escapes the space. (I put a 10" Kicker in there, and you couldn't hear it at all from inside the cabin). Between the rear trunk and the driver is the engine, so no need in trying that. My only recourse was to get something small and fit it inside the cabin. The airspace requirement of only .15cf is what drew me to the JL. I was VERY skeptical of a 6.5" sub. I'm used to 10's and 12's. But I thought I'd try it and whatever I got is what I would live with. I built a box that would fit the passenger footwell. When complete, it was so small it looked like a birdhouse. My son even laughed at me. That is, until I hooked it up. I was very surprised at the lows this little thing could crank out and the solid hit that it produced. And I'm still in the break-in mode! Can't wait to hear what it will really do. Nicest surprise I've had in a while. I'm gonna show my friends, let them laugh, then crank it up. If you have limited space, then this is your ticket. No way I would have ever believed it until I heard it.

Amazingly Tight Bass

Written By Michael, Illinois on Sunday, January 04, 2009
Crutchfield Customer Review (What's this?)
 
I've got two of these in the front of my car along with a pair of SR6500s for my sound stage. These speakers did a lot more than I expected. The bass is so punchy and tight. They really shine in the 65-120Hz range. I actually have my two 12" Infinity subs turned off because I prefer the tightness these small subs produce. Great sub for SQ applications! They can't turn out the deep lows like a larger sub can but you can definitely feel them pounding away!

Great sound from a small package

Written By William, Stamford, CT on Wednesday, January 16, 2008
Crutchfield Customer Review (What's this?)
 
I added two of these subs to my 99 Mustang GT convertible and the lows are really filled out now. I had upgraded the factory Mach 550 system with a Pioneer head unit, Polk DBs, and an Apline PDX 4.150. This setup was not strong on the low end, and got lost with the top down. There's not much room in the car for an additional amp or subs without loosing trunk space (small as it is), so I added another Apline (PDX 2.150), which fits under the passenger seat, and two 6.5" JL subs. They use small enclosures (.15 cu.ft.), so I built ones that go behind the front seats. They take up some rear seat legroom, but there's still enough room to sit in the back. The subs point at the front seatbacks, so when you crank it up, you hear it and feel it.
