JL Audio TW3-Series 10-Inch 400-Watt Automotive Subwoofer Driver, 4Ω or 8Ω DVC
The 10" TW3 thin subwoofer driver by JL Audio delivers a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than JL's W3v3 subwoofers!
JL Audio’s patented thin-line woofer technology compresses the architecture of the 10TW3 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 10-Inch thin subwoofer designs.
The 10TW3-D4 and 10TW3-D8 subwoofers are optimized for small enclosures and offer JL's tab-ear mounting design to maximize cone area within their mounting footprints.
- 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
- “concentric tube” architecture
- Patented “floating cone attach method” 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 at JL Audio’s Miramar, Florida factory with global components

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** For parallel-wired voice coils, divide "Re" by 4. All other specifications remain the same.
*** Re (DC resistance) is measured with the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications remain the same.
