About the JL Audio 12W3v3-4

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.

JL Audio W3v3 interior

The 12W3v3-4 subwoofer boasts a 12" 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.

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 1.125 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 23" W x 14" 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.)

Recommended Ported Box Volume: The ported box size recommended by JL Audio is 1.75 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 29" W x 14" H x 12.625" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, you should subtract 1/4" from each dimension.) A slot port is recommended with the following dimensions:

  • Slot Width=1.375"
  • Slot Height=12.5"
  • Slot Length=26.125" (a right angled port with a 13.5" extension)

Q
are ported boxes heavier than sealed boxes ?
[ rusty  Apr 09, 2019 ]
2 answers
A
Kind of depends on which type of port is used. If you use a thin walled plastic port it doesn't even add a pound but if you have a box that is ported with a wooden port than it will be weigh more. Is weight an issue for you because of the install or car performance?
[ JOHN P  Apr 11, 2019 ]
A
Generally yes because there are more material when constructing a ported box rather a sealed box

Q
Would the jl w3 v3 4ohm sub be paired well with the kenwood excelon xr600-1 amplifier?
[ nicholas  Oct 15, 2017 ]
1 answer
A
You have to match ohms, impedance and power from the amp to the sub. A 4 ohm sub needs to be powered by a 4 ohm amp, whether bridged or not. The ohms must match. Then you need enough power from the amp to move that sub. Find out the rms power of the amp, and max power the sub cab handle. The closer the better... it's math.

Q
2 JL audio 12 W3 V3 4 ohm subs in a sealed box with 2.1 ft.³ of airspace per side this is more air space then called for in the specs for the speaker will more airspace in a sealed box sound better or worse ?
[ Brian  Aug 12, 2017 ]

A
It should sound better. With my experience more space is better. Less is definitely bad.
[ Shaun  Aug 12, 2017 ]

Sealed boxes create deeper sound and are not punchy like ported boxes. I have a sealed box for my single 12w3v3. This sub pounds, it pounds really hard. I think you'll be fine with a little more air space. Just adjust the impedance and gain to maximize the subs potential. I actually have to lower my gain because the sub is hitting so hard, my head hurts I had an older version of this sub, the new one blows it away. The keys are to get the ohms, impedance and gain perfectly aligned with your amp.
[ JONATHAN  Aug 12, 2017 ]
A
Usually the required space for a subwoofer will yield the best sound or at least the design that the manufacturer is willing to warrant. Depending on the type of music you listen to, a ported box will give you more volume and vibration inside the car for hip hop, pop and even jazz. If you listen to instrumental, some types of rock, live sounds then a sealed box will give you more accurate, true bass.
[ Ricardo  Aug 12, 2017 ]
Q
Sealed box volume? I have one in sealed box built to specs and it isn't performing all that well at 300watts rms. Just got polyfill hoping that'll help. What size sealed box are people using?
[ Calvin  Apr 15, 2017 ]

I have a JL Audio factory built box that is the exact manufacture specifications and it shakes the earth. I have 2 subs being powered by a Rockford fosgate T-1000 and they hit hard enough to have pulverized my car. I've had only one sub going before and that sounds loud and clean but definitely not earth shattering like two. So my advice to to is if your box is built to specs then you either don't have a good enough amp or your taste in bass requires 2 subs. 300 watts seems like a lot but if it's not a high end brand that may be only peak watts not RMS. 12W3s are crazy power hungry and can easily handle 500 watts each if not more.
[ KYLE  Apr 18, 2017 ]

I have 2 of these in a sealed box with a volume of .95 cubic feet per sub. (The enclosures are separated within the box) they are being powered with 600w to each sub and sound fine.
[ william  Apr 18, 2017 ]

I have a 1.3 cube box per sub and a 1000 watt amp going to 2 12 w3 and it pounds hard,check your gain on your amp you might go to a bigger amp or a smaller amp keep them subs under 1.75 cubes and you should be ok at 300 watts.
[ TOM  Apr 18, 2017 ]
A
I prefer ported boxes for my 12" and 10" subwoofers because they sound louder. Sealed boxes are good for more precise bass, depending on the type of music of choice. My My 12" ported box is 1.6 cu ft. Hope this helps.

if your amp is 2 ohm stable then wire the subs in parrell by connecting + to + then to the + on amp then the same - to - then - on amp there are some great diagams under subwoofer on crutchfields site. http://images.crutchfieldonline.com/ca/learningcenter/car/subwoofer_wiring/2SVC_4-ohm_mono.jpg

Q
Should I get vented or sealed box for this? It's going in a trunk of a MINI Cooper. Thanks.
[ Craig  Jul 10, 2014 ]

A
I forwarded your question to an Advisor and they responded with the following: The JL Audio 12W3v3-4 can work in either a ported or sealed box. The type of box you use is based on what you're looking for in terms of sound quality. A ported box is going to give you deeper, louder bass while a sealed box provides more of a tight, accurate bass response. In general ported boxes do need to be larger, so if you're limited in terms of space you may want to go with a sealed box! If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
