12W7-3

W7 12-inch Subwoofer Driver (1000 W, 3 Ω) 

The 12W7 brings serious performance to the table by combining the breakthrough of the long-excursion W7 design with a large 12-inch bore. It has been called "addictive," "seductive" and "the new subwoofer reference," by some of the world's toughest reviewers, and has earned these accolades by delivering nearly limitless dynamics, exceptional balance and world-class sound quality.

This potent driver is best used with amplifier power in the 400W - 1000W range and is optimized to operate in a 1.375 cu. ft. (38.9 l) sealed enclosure, or a 1.75 cu. ft. (49.6 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
