Our take on the JL Audio 13TW5v2-2

You can get great-sounding, big bass in your sports car, truck, or any other compact vehicle. JL Audio rises to the challenge of compact spaces with their TW5 thin-line subwoofers. Engineered for use in extremely small boxes, these subs fit in places where only 6-1/2" or 8" subs would previously go, for astoundingly deep, resonant bass without the large enclosure.

JL Audio Built In USA Fit huge bass into tight spaces

You can get great-sounding, big bass in your sports car, truck, or any other compact vehicle. JL Audio rises to the challenge of compact spaces with their TW5 thin-line subwoofers.

This sub can fit places many subs can't.

A super-thin sub that rivals bulkier speakers

The 13TW5v2-2 13.5" subwoofer handles up to 600 watts RMS, while boasting a 2-5/8" mounting depth that makes it ideal for tight spaces. The cast-alloy frame provides a rock-solid platform for the mica-filled polypropylene cone and its resilient Santoprene™ rubber surround — you'll enjoy consistent, full-bodied bass output that won't distort under heavy excursion. The sub's 2-ohm impedance draws maximum power from your mono amp.

To drive this single subwoofer, we recommend a mono amplifier rated between 450 and 900 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Good subs

Pros: Everything

Cons: Price is steep

Pros and cons

Stephen from Pensacola, FL on 11/3/2015

I bought a couple of these as an upgrade from two Kenwood shallow mount subs that I originally had in my truck. They are great subs, and I can tell a bit of a difference in low-end output sound quality in my system. I am running these two subs on a Fosgate Prime 1200 amp putting out about 650 watts to each sub, and they have no problem handling the power. They were mounted in a custom box built by a local audio dealership. Luckily, I know the shop manager, so he was able to get me a pretty good deal on them. If not for that, I'm not sure I would have replaced the Kenwoods. These do hit harder than the Kenwoods do, and the lows are a bit deeper. If you have the money, you won't be disappointed. However if cost is a factor in your decision, there are lower priced alternatives out there (Kenwood and Alpine come to mind).

Pros: Sound quality Build quality Low-end response

Cons: Cost!! I thought I was going to pass out when I heard the total for the bill. Coolness factor is almost non-existent since mine are mounted in a down-firing box under the back seat of my truck.

Incredible Sub for the size

Thomas from Houston, TX on 10/15/2013

I bought this sub after about a month of research to find something that would sound great but would still be inconspicuous in my 11 silverado crew cab. Jl as most car audio enthusiasts know is tpp of the line. So I went ahead amd dropped the cash for it and I love it. The sound quality is amazing and the box is tiny considering how loud this thing is. If you're looking for a good sub without taking up very much space I highly recommend this one.

Pros: Pretty much everything!

Cons: Cost

Awesome Sub!!!

Pfunk from Virginia Beach, VA on 8/16/2013

Due to limited space in my Jeep, I previously had a Rockford Fosgate P3 shallow... I was decent (for a shallow mount). After I Blew (3 years later) I replaced it with JL's 13TW5v2-2.... WoW, what a huge difference!!! I plays very loud, deep and very clean... This shallow sub sounds better than many other "regular" 12s. You definitely get what you pay for with this sub.

Pros: Extremely clean, low and loud bass that you can really feel. Best shallow mount out there by a country mile.

Cons: Pricy (but worth it)


Hands-on research

Product Research


Thin-Line Design: The patented thin-line woofer technology compresses the architecture of the JL Audio 13TW5v2-2 subwoofer and allows it to deliver great bass performance in tight space applications, requiring only 2-5/8" depth. Central to the technology is the Concentric Tube structure that supports the oversized voice coil and the suspension attachments. This permits placing the motor structure much further forward in the speaker than in conventional designs, while maintaining excellent linear excursion capability. Equally important, the design is optimized for extremely small box volume applications.

Concentric Tube Suspension: A challenge in any low-profile woofer design is to permit enough mechanical clearance for the speaker to handle power and generate good output at low frequencies. JL Audio's patented solution employs a molded structure which spans over the edge of the motor system, supporting the spider on the outside of the motor's boundaries and the large diameter voice coil on the inside. The large voice coil permits the magnet to sit inside it, rather than surrounding the coil as is typical in most woofers. The concentric tube structure and the elimination of a conventional top-plate helps JL Audio move the motor structure into the cone body's space to further compress depth, while still permitting substantial mechanical excursion.

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 13TW5v2-2 motor maintains a linear force over a long excursion range and 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.

Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is a method of attaching the surround/cone assembly to the voice coil/spider assembly to maintain proper surround geometry, thus improving excursion control and dynamic voice coil alignment.

Voice Coil: To counteract the efficiency tradeoff of small box volume, the 13TW5v2-2 is designed to handle very high power levels thanks to the use of a very large 7-inch diameter voice coil.

Recommended Sealed Box Volume: JL Audio recommends a sealed box size volume of 0.8 ft³, resulting in a -3dB point of 41.18 Hz. A diagram is provided in the owner's manual for a sealed box with external dimensions of 19" W x 15" H x 7.75" D, assuming 3/4" thick MDF. (If using 5/8" thick MDF, subtract 1/4" from each dimension.)

Shallow Mount Design: The JL Audio 13TW5v2-2 only requires a mounting depth of 2-5/8" (top mounted).

Crutchfield asked  
Why did you buy this?

I need more bass in my car. The factory system just doesn't cut it. I didn't want to take up a lot of room with a big box. Hopefully this will do the trick. I've heard nothing but good things about this sub-woofer. [ Rodney  May 12, 2017 ]
They are ridiculous! [ Larry  Mar 09, 2016 ]
