JL Audio 12TW3 -D8

Discover the 12TW3 -D8, a 12" (30cm) subwoofer with an impressive sound, manufactured by the renowned manufacturer JL Audio. This subwoofer impresses with its high performance and low installation depth, and is based on the technological achievements of JL Audio's TW5 Thin-Line subwoofer. The 12TW3 -D8 is known for its remarkable performance, which is achieved through JL Audio's patented Thin-Line woofer technology. The subwoofer is characterized by its long linear excursions, its high resilience and its high power of 400W. As an extra, this subwoofer is particularly optimized for small installation spaces. Experience the difference that JL Audio makes with the 12TW3 -D8 can do in your audio setup.

• Building on the core technology of JL's TW5 Thin-Line subwoofers, the TW3 a powerful combination of low installation depth and high deflection. They are even able to achieve greater deflections than theW3 v3 subwoofer.
• To enable this remarkable performance, JL Audio's patented Thin-Line woofer technology compresses the architecture of the TW3 by a "Concentric Tube" structure built into the injection-molded cone body. This structure supports the voice coil and a full-ring spider while allowing the large motor structure to be placed further forward in the speaker than in conventional designs.
• The TW3 are optimized for small packages and feature JL's tab mounting design to maximize the cone area within their mounting surface. 
• Very low installation depth (3.50 inches)
• Very small requirements for the volume of the sealed housing
• Very long linear displacement (0.60 In / 15.2 mm, one-way linear displacement)
• DMA-optimized engine designs
• cast alloy frame
• Membrane made of injection-molded, mica-filled polypropylene
• rubber surround
• Aluminum alloy dust cap and rear cover with JL Audio logo
• Precision engineered in the USA at the JL Audio factory in Miramar, Florida, using global components
