JL Audio 13TW5v2-4 - 13.5" Dual 4-ohm Shallow Subwoofer

TW5v2 13.5-inch Subwoofer Driver (600 W, 4 Ω)

We couldn’t leave the ultimate thin woofer alone... we had to make it even better.

Our 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. Detailed enclosure recommendations can be found in the "Specifications" tab.

Never has such high-quality sub-bass been possible in the most challenging installation applications.

Creating great sounding bass is not that difficult when the available space in the vehicle is generous and you use high quality drivers. When space is limited (like in stealthy custom installations or behind the seats of a truck or sports car), achieving excellent low frequency performance becomes far more challenging.

One way to deal with this is to use small subwoofer drivers, like our 6.5-inch or 8-inch models, but if the goal is higher output bass than the small drivers can comfortably deliver, a more potent solution is needed.
This is precisely where the 13TW5 subwoofer slots into the lineup, offering groundbreaking performance in the tightest space applications. 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 design is optimized for extremely small box volume applications. Whereas a typical “small-box” 12-inch driver operates in well over one cubic foot, the larger 13TW5 is optimum in only 0.80 cu.ft. (significantly less volume than any other JL Audio 13.5-inch woofer).

To counteract the efficiency tradeoff of small box volumes, the 13TW5 is designed to handle very high power levels thanks to the use of very it's large voice coil (7-inch diameter).

So, if you're looking for premium subwoofer performance in the tightest spaces, you have not only found the shallowest automotive subwoofers on the market, but also the most capable. American ingenuity is alive and well.
