W6v3 10-inch Subwoofer (600 W, dual 4 ? voice coils) If you are seeking to reproduce the highest quality sub-bass in a very compact enclosure application, the 10W6v3 is the ultimate choice. This advanced Subwoofer offers several technologies shared with the flagship W7AE subwoofers to provide powerful advantages in motor linearity and suspension behavior. These combine with a very efficient cooling circuit to deliver reduced distortion and outstanding dynamic balance. The 10W6v3 is best used with amplifier power in the 200W - 600W range and is optimized to operate in a sealed enclosure with only 0.55 cu. ft. (15.6 l) of air space, or a 0.75 cu. ft. (21.2 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab. Greater excursion capability and higher power handling distinguish it from our 10W3v3 10-inch Subwoofer, allowing for higher output. Dual 4 ? voice coils permit deploying the W6v3 as a 2 ? or 8 ? driver.
