Overview

This groundbreaking subwoofer is the world’s first single-box, powered cardioid sub designed for both mobile and installed applications. Powerful and efficient, the QSC KS212C cardioid subwoofer solves the age-old problem of unwanted, wasted low-frequency energy collecting on stage and at the rear of the sound system. This powerhouse enclosure keeps your bass in its place and away from your stage or DJ booth.

Typical subwoofers radiate sound equally in all directions, including behind the enclosure where you don’t need it. Professional sound production companies have been able to combat this problem in recent years with complex, massive arrays of subwoofers in concert settings, changing the usual radial pattern of bass sound into a heart-shaped (cardioid) pattern that projects the lows into the crowd, not onstage. Before the KS212C subwoofer, a cardioid setup was impossible in a mobile setting, much less with a single, portable enclosure.

The pounding heartbeat of the KS212C cardioid sub is its potent 3,600W (peak) Class D amplifier, with the latest in DSP technology, driving two 12 in., long-excursion drivers for chest-thumping bass. Each driver is arranged in a 6th order bandpass chamber, producing an amazing 15dB more output in front than behind the sub.

With its robust, wooden enclosure and durable, tour-grade painted finish, the KS212C is built to withstand the rigors of heavy use. It also comes fitted with four low-noise, heavy-duty casters as well as ergonomic aluminum handles for easy transportation. Two M20 sockets provide speaker pole mounting options when the enclosure is upright or horizontal.

      Muscular, workhorse subwoofer for pros. Practical size and weight and a tuned, vented cabinet which throws in a cardioid pattern, making for a much tighter stage. At home on the road or as a permanent installation. They make a tidy cart/cover roll-around to go with. Long warrantee and good customer service. Industry leading technology.

        Absolutely loved the sound coming from these bad boys; not boomy. Was kicking so nice, an was asked to turn down the bass a couple times because of the neighboring building.

          I bought two of these to sit under my Alto 112's. Yep, you guessed it - I have to upgrade the 112's. I had to turn these down to 12 o'clock because the 112's couldn't keep up. My only gripe is with QSC for not setting the Frequency Response lower to capture the real sub bass present in many hip hop songs. These are the truth though for crowds up to 300.

          Comments about QSC KS212C K Cardioid Dual 12" Powered Subwoofer:

          This sub is impressive. I purchased it for a cafe sound system install. Connected to 2 QSC k10.2s This system is plenty powerful for a jazz band or just a mellow band. Everything from QSC has always been great quality However i was hesitant to purchase due to the old k-sub leaving much to be desired. This new one is almost as powerful as our kw181. Not quite as loud but hits hard and low. I would buy it again.
          If you're looking for something powerful, small, DSP smart, and super clear... this is it! Also the cardioid pattern projection is legit too.
