JL Audio 13TW5v2-4 13.5" 600 Watt 4 Ohm Shallow-Mount Subwoofer – #92183

JL Audio 13TW5v2-4 Shallow-mount 13.5" 4-ohm Subwoofer - #92183

13TW5v2-4 13.5-inch Subwoofer (600 W, 4 ohm) JL Audio's patented thin-line woofer technology compresses the architecture of the 13TW5v2 using a “concentric tube” structure that supports the 7-inch diameter voice coil and the suspension attachments. This permits placement of the large motor structure much further forward in the speaker than with conventional designs, while allowing excellent linear excursion capability and mechanical stability. To unleash even more performance from this technology, the v2 improves upon the original 13TW5 with 13% greater linear excursion capability.

The cast alloy chassis has also been modified for greater strength and the redesigned motor now features an annular vent. The v2 is also available in single 2 ohm and single 4 ohm voice coil versions to fit a wide range of applications. In keeping with its “tight-spaces” mission, the 13TW5v2 is optimized for enclosures that are far smaller than most 12-inch woofers require and only a bit larger than the air space needs of a typical, small-box 10-inch woofer. The mounting system is designed to fit in about the same footprint as a typical 12-inch woofer. The 13TW5v2 is best used with amplifier power in the 250W - 600W range and is optimized to operate in a 0.80 cu. ft. (22.7 l) sealed enclosure. Never has such high-quality sub-bass been possible in the most challenging installation applications.

Fit huge bass into tight spaces

You can get great-sounding, big bass in your sports car, truck, or any other compact vehicle. JL Audio rises to the challenge of compact spaces with their TW5 thin-line subwoofers. Engineered for use in extremely small boxes, these subs fit in places where only 6-1/2" or 8" subs would previously go, for astoundingly deep, resonant bass without the large enclosure.

This sub can fit places many subs can't.

A super-thin sub that rivals bulkier speakers

The 13TW5v2-4 13.5" subwoofer handles up to 600 watts RMS, while boasting a 2-5/8" mounting depth that makes it ideal for tight spaces. The cast-alloy frame provides a rock-solid platform for the mica-filled polypropylene cone and its resilient Santoprene™ rubber surround — you'll enjoy consistent, full-bodied bass output that won't distort under heavy excursion. The sub's 4-ohm impedance makes it a great candidate for multi-sub installations.

13TW5v2-4 Features:

Thin-Line Design: The patented thin-line woofer technology compresses the architecture of the JL Audio 13TW5v2-4 subwoofer and allows it to deliver great bass performance in tight space applications, requiring only 2-5/8" depth. Central to the technology is the Concentric Tube structure that supports the oversized voice coil and the suspension attachments. This permits placing the motor structure much further forward in the speaker than in conventional designs, while maintaining excellent linear excursion capability. Equally important, the design is optimized for extremely small box volume applications.

Concentric Tube Suspension: A challenge in any low-profile woofer design is to permit enough mechanical clearance for the speaker to handle power and generate good output at low frequencies. JL Audio's patented solution employs a molded structure which spans over the edge of the motor system, supporting the spider on the outside of the motor's boundaries and the large diameter voice coil on the inside. The large voice coil permits the magnet to sit inside it, rather than surrounding the coil as is typical in most woofers. The concentric tube structure and the elimination of a conventional top-plate helps JL Audio move the motor structure into the cone body's space to further compress depth, while still permitting substantial mechanical excursion.

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 13TW5v2-4 motor maintains a linear force over a long excursion range and stable, fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.

Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is a method of attaching the surround/cone assembly to the voice coil/spider assembly to maintain proper surround geometry, thus improving excursion control and dynamic voice coil alignment.

Voice Coil: To counteract the efficiency tradeoff of small box volume, the 13TW5v2-4 is designed to handle very high power levels thanks to the use of a very large 7-inch diameter voice coil.

Recommended Sealed Box Volume: JL Audio recommends a sealed box size volume of 0.8 ft³, resulting in a -3dB point of 41.42 Hz. A diagram is provided in the owner's manual for a sealed box with external dimensions of 19" W x 15" H x 7.75" D, assuming 3/4" thick MDF. (If using 5/8" thick MDF, subtract 1/4" from each dimension.)

Shallow Mount Design: The JL Audio 13TW5v2-4 only requires a mounting depth of 2-5/8" (top mounted).
