Are you looking for a portable, easy-to-use cardioid subwoofer? Then look no further than the dual 12" QSC KS212C, a single-box powered cardioid subwoofer solution for mobile entertainers, AV production, and rental professionals as well as modestly sized performance venues. The subwoofer features a 3600W Class-D amplifier module that powers two 12", long-excursion drivers in a dual 6th order band-pass design that creates a cardioid polar pattern with -15 dB SPL front-to-rear attenuation. The unit offers a frequency response of 44 to 104 Hz (-6 dB) with a peak SPL of 132 dB (at 1m).
Typically, subwoofers are omnidirectional, radiating in all directions. This results in a build-up of low frequencies on-stage and wasted LF energy at the rear of the system. Sound engineers found a way to create a cardioid (heart-shaped) polar pattern, which removes much of the low energy at the rear of the subwoofers. Unfortunately, this system required the use of subwoofer arrays with multiple enclosures, clever placement, and processing of delay and polarity to redirect the energy.
The KS212C provides all the benefits of a cardioid subwoofer array, but without the headache of multiple enclosures and outboard processing. The single subwoofer can be deployed in a vertical or horizontal position and features M20 speaker pole fittings in either position, while the 15mm Baltic birch enclosure features a rugged paint designed for long-life and lasting durability. The rear panel offers a LCD control module with variable crossover and savable and recallable scenes as well as Intrinsic Correction tuning and loudspeaker management. There are two combo XLR-1/4" inputs and two XLR "Pass-Thru" outputs. The KS212C ships with a locking IEC power cord.
