About the JL Audio 12TW3-D4
Bass for challenging spaces
Bass for challenging spaces
If you've got a pickup truck, sports car, or you just need to haul a lot of stuff, then you know that adding some bass can be a challenge. That's why JL Audio built the TW3 Series 12TW3-D4 shallow-mount subwoofer. This super-thin 12" sub puts out big bass, yet only requires minimum air space, so you can use a much smaller enclosure. Now, you can have your bass and your space too.
Don't let this sub's low profile fool you, it's made for big bass.
JL Audio's amazing engineering
JL Audio used all their tricks to build a sub this slender without giving up performance. Its tough polypropylene cone won't flex under high power, and the large, durable rubber surround helps the cone move large amounts of air. The heavy-duty cast-alloy frame only stands 3-1/2" tall, but provides a stable home for this high-performance bass driver. For best results, you'll want to send this sub up to 400 watts RMS, and its dual 4-ohm voice coils make it a perfect match for a mono amplifier.

JL Audio 12TW3-D4 reviews
I had these JL Audio subs installed into my 2012 Chevy Impala with a custom box to the proper air space. Which is about the size of a 10 inch box. I still have the majority of space in the trunk of the car. Which is what i wanted. Yes, these subs are a bit expensive. But once i got everything tuned. I was amazed! I have a JL Audio 1,000 watt amp running these subs. Turned down a little bit. The sound is great. Great low bass! I'd recommend these to anyone who is looking to maximize space or use under the back seats of a truck or suv. I've heard in other reviews people mentioning the $60 cost difference between these and the W3's. It all comes down to 3 things. 1) How much is you budget. 2) Is there any wiggle room to your budget. 3) Is sacrificing quality for cost worth it in the end? I was going to go with different shallow mount subs. But going cheaper and expecting similar quality doesn't usually go hand in hand!
Pros: Shallow, Space saver, Quality

Lows are really impressive, but the mids are a bit muddy. Maybe after a proper break in, this will improve.
Pros: Deep bass, space saver
Cons: Price. They protrude much more than a standard woofer when installed. Had to lift my down firing box to make room.

Very good sounding sub, JL always has premium products. The downfall is the price range. Compaired to a normal w3, 60 dollar difference seems a bit of gouging to me.
Pros: Great sounding and fits anywhere.
Cons: Price point

Installed two of the JL 12" in my 2015 Toyota Tacoma in a custom box that I built. Pairs with an alpine mono amp. 400 Watts rms going to each sub. Hits hard and also catches all the lows. I would Recommend these to anybody.
Pros: Fits in tight spaces and still packs a punch

Great sounding sub. Hits all the notes and doesn't skip a beat. I will buy another one when I need it. And would recommend to anyone looks for a awesome sounding sub for a tight space. I paired it with a JX 500/1D. Sounds amazing
Pros: Big sound in a tight space and in a small box
Cons: None at all

Installed this in my 2014 JKU on a JL 900w HD 5 channel with my highs. Built a custom box for it and it sounds amazing. A whole lot of knock out of a shallow mount speaker. I love it. Paired with the TW1 10" and they make a nice duo. Hitting beautifully. Can't wait to add another 10" to complete my build
Pros: Big sound Low space required Wide range Clear sound Pairs well with other JL TW subs
Cons: I can only fit 1 ;)

This subwoofer is a great deal for the price. I installed it into a shallow down firing box with a Kenwood X501-1 amp, and wired at 2 ohms resistance. It has an impressive amount of bass for the price and size of the unit. Even with the head unit bass level set way back it still hits hard enough to rattle you. I wish i could also fit it in the underseat box of my Ram 2500, but it is too wide unfortunately. I would highly recommend this sub and would also purchase again if doing another similar build. Be aware that the required cutout for this sub is slightly bigger than many others and may not directly fit it all, especially older, boxes.
Pros: price size sound quality ability to run 2 ohms

don't officially have it hooked up yet, making a custom for it in the back of my supra. Did hook it up without the other speakers and seemed to be good. It will be replacing a 15" kicker and sounded like I won't lose any performance and may gain performance, and it takes up half the room. I have tried a few different subs to replace the kicker and always sent them back. I will be keeping this one.
Pros: powerful, takes little room, hits hard
Cons: didn't come with a grill

Needed a shallow mount sub for the small trunk in my IS250. I was not too impressed with the SQ of an Alpine Type R thin sub that I had in a sealed box, and I've had great results with JL subs in a vented enclosure so I decided to try this sub. After making the vented enclosure dimensions I got off the JL website a half inch shorter I was able to squeeze the enclosure into my car and still have full access to my spare tire. Funny thing is the instructions that come with the sub recommend sealed enclosures only, but JL has vented enclosure dimensions on their website. Now for the sound. I have an old JL 500/1 powering this thing. It plays deep and relatively musical like a sealed sub yet has strong output. I definitely recommend this sub for those pressed for space, and the vented enclosure is absolutely worth the hassle of building.
Pros: shallow mounting depth, absolutely pounds in a vented enclosure
Cons: wish the two voice coil terminals on the sub were close together like on the W6.

Great product! This is exactly what I needed to add some extra bass when I didn't have a lot of room to spare. This shallow mount sub fit perfectly under the back seat of my Silverado crew cab. It's built strong and hits hard. I am very pleased.

Great sub just make sure you know up front that this sub was a little bigger around than a normal 12 inch sub woofer had to cut the hole in the box a little bigger to fit. Also if you install this in a down firing box make sure the foam isn't going to touch thefloor on excursion, this sub also takes very little airspace had to block off half my box in the inside to make it sound decent enough to listen too
Pros: Great sub for small air space situations
Cons: Foam sticks out a little on excursion rubbed the floor a little

Recently replaced two Alpine type Rs, with this single sub. I have no experience in CarAudio. My son is way more knowlegable, but I can say this: The TW3 sounds cleaner than did the Alpine setup. Same Amp. Same Headunit. I am hardly an authority on SPL, but the sub hits hard to me, and it is as loud as I want it to be. It rocks.
Pros: Retains my stock look in the 2010 Toyota Tundra. Rounds out my sound with excellent sound quality and hits hard. Perfect bottom end.
Cons: I guess it is a bit pricey, but that is all relative.

This sub right is here is the best for small enclosures. I am using a single 12 behind the seat of a crewmax and didn't lose much room. The sub sounds great and hits hard.
Pros: Small space .80cu and 800watts. what more can you ask for

This sub replaced my 10w6v2. It fits in basically the same size box but much better output.
Pros: Good output, very small box

Excellent compact sub. Running a 400 watt mono amp to it where it's hidden in the spare tire well of my convertible mustang and it bangs.

JL The best on subwoofer , I have tried quite a few different brands and shallow subs on the market and this is the best I have ever own and it hasn't been break in YET so that goes to tell you how good this sub is although it's a bit pricey , but you get what u pay for and that's QUALITY and on top of that you can add the tech support from Crutchfield for life and in my experience with them since 2006 THERES NO other place with the quality items and treatment to clients like them and trust me when I'm saying that I have order and still do from websites that are based here in CA , FL and NY that I rather not mention names cause I still order from them small items specially here in CA as I get them over night as I live here too and used them to work on cars the next day but even though they are here , they don't update their availability and won't get ship or won't call u , email u to just let you know that the item is out of stock so you called them and they are so rude to you or they have already charge you for the item and they just tell you that they don't know when it will be in stock and of course it takes a week for them to reimbursed your money back to your credit card , unlike Crutchfield they have always been so so professionals too bad they are not in CA .

If you have the money to expend and are a sound enthusiast, definitely you must get this Sub. Excellent sound quality, state of the art design and materials. Perfect design for small enclosures. Fits even in the smallest boots.
Pros: Shallow design. Excellent "Bose" bass sound quality. Excellent materials. Fits perfectly even in smaller cars or trucks. Easy to read instructions. (Enclosure and connections) Cool look.
Cons: its a bit overpriced but you may survive to this after a few tracks.

Amazing sound it a small package. Dont waste your time trying other shallow mount subs. There is only one real shallow mount that gives you the sound quality of a full size sub and JL sells it.

Thin-Line Design: JL Audio's patented thin-line woofer technology compresses the architecture of the 12TW3-D4 subwoofer and allows it to deliver great bass performance in tight space applications (less than 3½" deep). 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 conventional designs, while maintaining excellent linear excursion capability. Equally important, the 12TW3-D4 is designed for extremely small enclosure applications; 0.8 ft³ is optimum.
Concentric Tube Suspension: JL Audio's patented Concentric Tube Suspension employs a molded structure which spans beyond the edge of the motor structure, 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 place the motor higher up into the cone body's space to further compress depth, while still permitting excellent mechanical excursion.
Mica-Filled Polypropylene Woofer: The subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a rubber surround for added durability, woofer excursion and bass response.
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 12TW3-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.
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.
Recommended Sealed Box Volume: The sealed box size recommended by JL Audio is 0.8 ft³. A diagram is provided in the owner's manual for a sealed box with external dimensions of 21¼" W x 16" H x 6½" D, assuming ¾" thick material. (If you are using ⅝" thick materials, subtract ¼" from each dimension.)
Ported Box Volume: JL Audio recommends a ported box volume of 0.95 ft³. A diagram is provided in the owner's manual for a ported box with external dimensions of 30" W x 16⅝" H x 6½" D, assuming ¾" thick material. (If you are using ⅝" thick materials, subtract ¼" from each dimension.) A slot port is recommended with the following dimensions:
- Width: 5"
- Height: 2½"
- Length: 31¼"
Shallow Mount Design: The JL Audio 12TW3-D4 requires a mounting depth of less than 3½".
