About the JL Audio 8W3v3-4

JL Audio Built In USA Remarkably realistic bass

JL Audio designed 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. The W3v3 sub works well in a sealed or ported enclosure.

Well-rounded performance

JL Audio W3v3 interior

The 8W3v3-4 subwoofer boasts an 8" 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.

Product Research

Enclosure Compatibility


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 0.30 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 12" W x 10" H x 8" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, you should subtract 1/4" from each dimension.)

Recommended Ported Box Volume: The ported box size recommended by JL Audio is 0.35 cu/ft. A diagram is provided in the owner's manual for a ported box with external dimensions of 12.5" W x 10" H x 9.25" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, you should subtract 1/4" from each dimension.) A rounded port is recommended with the following dimensions:

  • Diameter = 2"
  • Height = 18"

There is at least 4.889" (8" if its the coupe) mounting depth for the stock subwoofer in those cars

what is the total mounting depth for the rear center channel sub 2013 genesis?
[ BAMBAM  May 22, 2020 ]
1 answer
The JL recommended space for a sealed box is 0.30 cu ft., for example the dimensions on a .75 in. box would be 10x10x9.5 in. Mounting depth of the woofer is 4.63 in. Pulled from the JL site. This woofer will not work without an enclosure.

Are you asking about a kit designed to let you repair/replace the voice coil in this sub? If so, there is not. You can reach out to JL Audio if the sub is still under warranty, they may be able to help you out.

I am trying to find a better alternative to what the internet say is BMW owner's only choices. 2012 E92 335i N54 coupe msport is what im rolling. Harmon kardon sound. BMW's owners say really only two will fit the bavsound and earthquake sws. HK mids and high are overpowering lows. Can this fit and be a viable option of course with amp replace? dont want to hit hard but i want more than those two subs can offer
[ Jason  Sep 21, 2018 ]

Sorry, no; as with most aftermarket subwoofers, we found the JL Audio 8W3v3-4 to be much too large for the available mounting space in the stock subwoofer location. The available mounting depth is the major issue but the magnet diameter & mounting height (grill clearance) are also problems. For additional assistance and personalized recommendations, feel free to contact us directly by phone or through our online chat service:
[ Ryan  Oct 03, 2018 ]  Staff
can these be used in motorcycle bags?
[ eric  Sep 02, 2018 ]
2 answers
No. Not enough air space or mounting surface
[ Shaun  Sep 07, 2018 ]
The JL Audio 8W3v3-4 is designed to mount into a separate subwoofer enclosure (sealed or ported); and wouldn't typically be recommended for use on a motorcycle. However, if you'd like to discuss mounting options in more detail, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. They can provide more personalized advice for your system to give you a better idea about fit and/or compatibility. Thanks!

What's the difference between the 8w1v3 and the 8w3v3 ..... other than the price??

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Can you use these in the rear deck, open air install in the trunk?
[ sport  Apr 26, 2016 ]
3 answers
[ Shaun  Sep 07, 2018 ]
They cannot be used as free air subs. They need to be in a box.
[ Sean  Apr 27, 2016 ]
No, they require an enclosure.
[ kyle  Apr 27, 2016 ]
how do these speakers perform installed in car doors?
[ john  Nov 24, 2015 ]
2 answers
They don't
[ Shaun  Sep 07, 2018 ]
Not very well at all. They will be too deep for most vehicle doors and, like most aftermarket subwoofers, you'll need an enclosure with the proper airspace for the best performance. I hope that helps!
[ Ryan  Nov 27, 2015 ]  Staff
What gauge speaker wire is recommended to run from the amp to this Sub? About 8 feet in length.
[ David  Oct 30, 2015 ]
2 answers
14 or 12
[ Shaun  Sep 07, 2018 ]
Electricity flows like water. So the bigger the wire, the more easily power is passed. Obviously, too big is ridiculous, so find out the minimum and go a gauge or three bigger. Hope this helps!
