Our take on the JL Audio 6W3v3-8

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 6W3v3-8 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.

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.)

Nice Bass in a Little Package.

Crutchfield Customer Review (What's this?)
 
I picked up this JL 6W3v3-8 to go in my 2001 Chevy Silverado Z71 to add a bit of low end to my system without attracting too much attention or taking up too much room in the cab that I currently use for tools. Well, it fit this bill very well. It added tons of lows, more than I expected from such a small sub. Now my system sounds GREAT! I run it with the new JL XD600/6 amp. I bridged channels 5 and 6 on this amp and get 150 watts to the 8 ohm sub. According to JL their 6W3v3 subs should not be run over 150 watts or you void the warranty. This is why I picked the 8 ohm 6W3v3 over the 4 ohm model. Under 4 ohm load the XD 600/6 puts out 200 watts (warranty voided!).

Enough of that, what's important is how it sounds. And it sounds GREAT! When I really turn it up I was surprised to see my mirrors vibrating from the bass and how I could feel it in the seat. It is very clean and works well in a very small enclosure. I have it in a .18 cubic foot sealed enclosure and WOW! For a 6.5" sub it really works fantastic and adds lows to my music without everyone else hearing it outside of my truck. And the small box makes it easy to keep out of sight. I would definitely get one of these if you want a bit more bass in your ride without taking up to much room. But if you REALLY want to be heard, get a bigger sub.
