JL AUDIO - 12w1v2

Subwoofer Drivers

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.)
