JL Audio 12TW3-D4
TW3 12-inch Subwoofer Driver (400 W, dual 4 Ω voice coils)
Building on the core technology of our TW5 thin-line subwoofers, the new TW3’s deliver a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than the W3v3’s.
To allow this remarkable feat to be achieved, JL Audio’s patented thin-line woofer technology compresses the architecture of the TW3’s using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of the large motor structure further forward in the speaker than with conventional designs.
TW3’s are optimized for small enclosures and offer our tab-ear mounting design to maximize cone area within their mounting footprints. We know you’re going to love working with these amazing subwoofer drivers.
Deep, powerful and accurate JL Audio bass is now possible in more applications than ever.
- Very shallow mounting depth (3.25 / 3.50 Inches)
- No pole vent: permits mounting close to rear wall of enclosure.
- Very small sealed enclosure volume requirements

- DMA-optimized motor designs
- Patented “concentric tube” architecture
- Patented “floating cone attach method” technology
- Cast alloy frame
- Injection molded, mica-filled polypropylene cone
- Rubber surround

Refurbished FAQ
Refurbished Frequently Asked Questions
- What does refurbished mean? Refurbished products may be unused customer returns that are essentially "new" items, or they may be defective products that were returned under warranty, and resold by the manufacturer after repairing the defects and ensuring proper function.
- What is the warranty? All of our manufacturer refurbished items come with a 90-day warranty. Compared to the new products we carry generally having a 1-year or longer warranty. (JL Audio Amps are 2-years, and all of Wet Sounds carries a 2-year warranty when new)
- What's it look like? A lot of the manufacturer refurbished products we sell generally look very good, and sometimes you can't even tell. However, these products can have some wear and tare on them, and we generally rate them an 8/10 cosmetically, and perfect 10/10 functionally.
- What was wrong with it? We aren't told what is wrong with each and every product. Like stated above, they could have just been a return or they may have had an issue. Regardless, they are all combed over by their respective manufacturer to function as new before being shipped to us.
