QSC KS212C

The QSC KS212C subwoofer is the world's first active single-box cardioid subwoofer for portable entertainment and installation applications. A breakthrough in innovation and design, the 3600W QSC KS212C subwoofer uniquely provides all the benefits of cardioid placement in a single, compact package housing. "Holding the bass in place", the KS212C subwoofer is unrivaled in managing low frequencies on stage or in other applications where unwanted low frequency energy needs to be minimized. Equipped with a 3600W Class D amplifier, the latest DSP technology, dual 12-inch long-throw drivers, each housed in a sixth-order bandpass chamber, all these components combine flawlessly to produce an astonishing 15 dB more output at the front of the cabinet than at the rear. The QSC KS212C subwoofer is highly portable, with comfortable aluminum handles and four wheels mounted on the back. Two M20 sockets accept a 35mm speaker pole in either a horizontal or vertical orientation.
