The Black Air 12 inch Dual 2Ω Subwoofer is for those who want sound quality to be loud. The new Black Air subwoofers offer dynamic, accurate bass but with the extra volume you want for showing off. Using double stacked magnets, Vibe’s Blackhole dust caps and high roll foam surrounds, the Black Air 12 inch Dual 2Ω Subwoofer offers beautiful bass but with the aggression of the larger competition subwoofers.
