The patented thin-line woofer technology compresses the architecture of the woofer to make it all happen. Central to the technology is the "concentric tube" structure that supports the oversized voice coil and the suspension attachments. This permits placing the motor of the woofer much further forward in the speaker than with conventional designs, while maintaining excellent linear excursion capability.Equally important is the fact that the TW5 designs are optimized for extremely small box volume applications. The 13TW5 is optimum in only 0.80 cu. (significantly less volume than any other JL Audio 13.5-inch woofer).
To counteract the efficiency tradeoff of small box volumes, the TW5's are designed to handle very high power levels thanks to the use of very large voice coils (7-inch diameter). Extremely Shallow Mounting Depth (2.5 inches).Extremely Small Sealed Enclosure Volume Requirements. Patented "Concentric Tube" Suspension Design. Patented "Floating Cone Attach Method" Technology. Very Large Diameter Voice Coil. Injection Molded, Mica-Filled Polypropylene Cone with Santoprene Surround. 13-1/2 Single 4 ohms TW5 Thin-Line Subwoofer. Unique design allows for small airspace requirements. Requires only 0.8 cubic feet of airspace. You will be issued a Return Authorization Number.
