Our take on the JL Audio 12W6v3-D4

by John Pollard
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.

Pole-venting helps the sub stay cool when you turn the volume up.

Bass that means business

JL Audio's celebrated W6v3 subwoofers deliver knockout low end with incredible accuracy. The 12W6v3-D4 12" subwoofer uses a tough, mineral-filled polypropylene cone that offers incredible strength without the added bulk that can slow woofer response. JL Audio conducted extensive research to develop a motor structure that operates efficiently and precisely, so this sub can deliver powerful, reliable bass while handling up to 600 watts RMS. Exclusive cone-bonding assemblies, advanced cooling systems, and a highly stable spider attachment enhance reliability and promote long performance life.

Precision-crafted low end

The sub's solid cast-alloy basket allows your W6v3 sub to handle big-time power without any distortion-causing flexing. A sophisticated suspension system promotes linear cone movement for greater accuracy. The simple terminal jumper wiring system allows you to set the subwoofer's impedance to draw maximum power from your amplifier, or to design a multi-sub setup.

Get the sound and look you want

The elegant JL Audio medallion on the front shows the competition you mean business. Go for a special look with the removable black trim ring, which can be painted to match your installation theme. The 12W6v3-D4 works best in a compact enclosure, so you can get great bass in some tight places.

Features

Dual Voice Coils: Due to the 12W6v3-D4's dual 4 ohm voice coils, the subwoofer can be configured as a 2-ohm (voice coils wired in parallel) or 8-ohm (voice coils wired in series) driver. The included jumper wires allow easy adjustment from one configuration to the other (the factory jumper position is 2-ohm).

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 12W6v3-D4 motor remains linear over a long excursion range, and also maintains a stable fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.

Pole-Vent Airflow Control (PVAC): The bullet-shaped structure inside the pole-vent directs airflow and increases air velocity to effectively reduce voice coil temperature, leading to improved fidelity and reliability.

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.

Elevated Frame Cooling System: The elevated frame design of the 12W6v3-D4 delivers cool air 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.

Customizable Trim Ring: The woofer has 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 an optional mesh grille insert specifically designed to fit into the inner diameter of the trim ring (item number 136SGR126, sold separately).

Engineered Lead Wire System: JL Audio's engineered flying lead-wires have carefully engineered entry and exit support structures molded into the terminals and the voice coil collar and are jacketed to further reduce the likelihood of shorting and fatigue. The result is predictable high-excursion lead-wire behavior with long term reliability, and none of the compromises inherent to a woven-in lead wire system (when attached or woven into the spider material, lead-wires can alter the spider's motion, leading to asymmetrical spider behavior).

Enclosure Compatibility

Sealed Enclosure: JL Audio recommends a sealed box size of 1.105 ft³ (1.0 ft³ net, plus the sub's 0.105 ft³ displacement). A diagram is provided in the owner's manual for a sealed box with external dimensions of 15" W x 15" H x 12" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, subtract 1/4" from each dimension.)

Ported Enclosure: The ported box size JL Audio recommends is 1.405 ft³ (1.3 ft³ net, plus the sub's 0.105 ft³ displacement). The recommended slot port is 12-1/2" x 1-1/2" x 31-5/8", resulting in a tuning frequency of 33 Hz and a -3dB point of 31 Hz.

Breaking In

Written By AC, Columbia, S.C. on Saturday, May 31, 2014
Crutchfield Customer Review (What's this?)
 
I never really understood this whole breaking period with subwoofers, Until I purchased these w6's. the amount of air they move fresh out the box is amazing. And they continue to get louder as the very stiff cone starts to give into the bass. This brand of sub found bass in song that I didn't know was there and I can say I happy to have finally have bought a set.
Pros:
The warranty after you blow them. Good clear bass all day.
Cons:
Not compatible with weak home style wiring kits. You need some professional wiring to move the subs to really get what you've paid for...

Awesome

Written By Rex J, Walnut Ridge, AR on Wednesday, February 19, 2014
 
I have owned numerous subs over the years. Cheap and expensive. This is a great sub. I picked one up locally for a great deal. It beats the heck out of Challenger. They are big cars and it's hard to get quality sound from the trunk to the cabin. But this thing delivers...In SPADES. If there is room in your audio budget. I say go for it.
Pros:
Sound quality, performance, awesome good looks, Too bad it's in the trunk and I can't look at it.
Cons:
Power hungry, it's in the trunk, I never get to look at it. Kind of expensive.

1 question already asked

How many of these subs can u run at once? Odds, evens, & or both? [ Joey  Dec 22, 2013 ]
1 answer
  • That depends on the amps you are running. Read up on "ohms law" for every speaker you double up on an amp output, you are decreasing the ohm rating by half. If the speaker is rated at 4 ohm and your amp is rated as 2ohm stable, then you could run 2. As for the 10w6, I don't know how much bass you are trying to get, but those subs hammer. I have one in my wife's Acura TL-S and one in my Yukon Denali and both cars rock. Hope this helps. Robert [ ROBERT   Dec 22, 2013 ]
