QSC KS212C Powered Cardioid Subwoofer

The 3,600-watt QSC KS212C powered cardioid subwoofer provides the ability to manage low frequencies in a variety of environments. Internally the KS212C employs a Class D amplifier power module that drives a pair of 12-inch long-excursion woofers in a dual sixth-order band pass design. QSC explains that through its cardioid design the subwoofer is able to produce 15dB more output from the front of its cabinet, and the portability of the sub is enabled through its aluminum handles and rear-mounted casters. QSC rates the frequency response of the KS212C at 44Hz to 104Hz.
