JL AUDIO 12TW3-D8

JL AUDIO

(12TW3-D8) 12-INCH THIN-LINE SUBWOOFER DRIVER (400W, DUAL 8 OHM VOICE COILS)

OVERVIEW:

• Building on the core technology of our TW5 thin-line subwoofers, the 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 Subwoofers.
• 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
• “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
