W1v2: Technologies

W1v2 Subwoofer Drivers
The all-new W1v2?s are poised to establish a new standard for affordable bass excellence thanks to technologies originally developed for our flagship W7 and W6v2 subwoofers.

These include JL Audio?s patented VRC?, Elevated Frame-Cooling and Floating Cone Attach Method? technologies, along with an innovative, insert-molded spider assembly with integral push-terminals and special strain-relief features.

As with JL Audio?s flagship drivers, development was guided by JL Audio?s proprietary DMA modeling system to deliver outstanding dynamic stability and low-distortion operation within their intended power envelope. Optimized for compact enclosures and moderate power levels, and specifically engineered to reduce mounting depth, the W1v2's open up a whole new range of application options.


An injection-molded, metallic-finish polypropylene cone with an embossed metallic JL Audio logo provides a classy new look, while a removable (and customizable) mounting flange trim ring receives grille-mesh inserts directly, without the need for additional grille hardware. (Grille mesh inserts are sold separately.)
Available Models:
10W1v2
12W1v2
13W1v2
