12W0v3-4
12-inch (300 mm) Subwoofer Driver, 4 Ω
WØv3 12-inch Subwoofer Driver (300 W, 4 Ω)
The 12WØv3 is a rugged performer with excellent efficiency, excursion capability and linearity. Its overall performance envelope that puts it right at the top of its price class. It features a beefy 2 in. diameter voice coil and our patented Elevated Frame Cooling design for enhanced power handling and reliability.
The 12WØv3 is best used with amplifier power in the 75W - 300W range and is optimized to operate in a moderately sized 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.
