Product Details

MK Sound M SB-12 Black 12" Subwoofer Speaker, Model SB12BK

From the world leader in high performance subwoofer design, the M Series SB-12 Deep Bass Powered Subwoofer is an MK thoroughbred, giving you the audible superiority you expect from MK at a remarkably affordable price in an incredibly compact size. The SB-12 all-discrete power amplifi er design offers exceptional sonic quality and ample power at a conservatively rated 250 watts continuous output. The SuperFast Deep Bass Driver and exclusive MK Headroom MaximizerTM ensures a potent, yet tightly controlled bottom end for all your listening needs. For precise fi ne-tuning of the critical transition between the subwoofer and the main speakers, SB-12 incorporates a phase control that is continuously variable between 0 and 180 degrees. To facilitate easy connection to ANY system, the SB-12 includes inputs and outputs for line level and speaker level signals. A convenient signal detection circuit, automatically turns the subwoofer on when a signal is present and places it in standby after a period with no signal. The SB-12 delivers explosive home theater performance and possesses the articulation and clarity necessary for true musical enjoyment.
