The Black Diamond DIA-T12.4D 12″ Subwoofer delivers impressive 2000W Max Power and once you hear it, you will finally realize what big, rich bass sounds like. This DIA-T12 puts out all of the power you need and handles low frequencies like a sub twice the price. Dual Voice Coil provides multiple options and flexibility to wire Parallel, Series, or Independent. DVC will make sure you get the most from your system. While typical subwoofers have a single voice coil, Black Diamond offers two. Settle for nothing but the best with Ferrite magnets that produce a wider range of tones and can handle tremendous power at high volumes.
