JL Audio 12TW3-D8
TW3 12-inch Subwoofer Driver (400 W, dual 8 Ī© voice coils)
Building on the core technology of our TW5 thin-line subwoofers, the new TW3ās deliver a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than the W3v3ās.
To allow this remarkable feat to be achieved, JL Audioās patented thin-line woofer technology compresses the architecture of the TW3ās using a āconcentric tubeā 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.
TW3ās are optimized for small enclosures and offer our tab-ear mounting design to maximize cone area within their mounting footprints. We know youāre 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
- Very long linear excursion capability (0.60 In / 15.2 mm, one-way)
- DMA-optimized motor designs
- Patented āconcentric tubeā architecture
- Patented āfloating cone attach methodā technology
- Cast alloy frame
- Injection molded, mica-filled polypropylene cone
- Rubber surround
- Aluminum-alloy dust cap and rear cap with JL Audio logo
- Precision-built in USA with Global Components at JL Audioās Miramar, Florida factory
