Powered by a 3,600 Watt Class D amplifier, processed with the latest DSP technology, and featuring dual 12-inch long excursion drivers each arranged in a 6th order band pass chamber, these components all combine seamlessly to produce a staggering 15 dB more output at the front of the cabinet than at the rear. Highly portable, the cabinet features comfortable, aluminum handles and four, rear-mounted casters. Two M20 sockets accept a 35 mm loudspeaker pole in either horizontal or vertical orientation.
Most subwoofers radiate energy around the entire
enclosure, leading to undesirable LF build-up on stage
and wasted energy around the sides and rear of the system
The KS212C subwoofer keeps "bass in its place"
with a single-box cardioid array that produces an
amazing 15 dB more output at the front than at the rear
