Typical subwoofers radiate sound in every direction. This creates undesirable low-frequency build-up onstage and wastes energy. The QSC KS Cardioid powered subwoofer solves this problem. It redirects the energy forward, minimizing low-frequency clutter behind the system. In fact, the KS Cardioid subwoofer produces 15dB more output at the front than at the rear. The QSC KS Cardioid powered subwoofer features a dual sixth order bandpass design, efficient Class D amplifier, and the latest DSP technology to ensure top-notch sound and maximum low-frequency response.
When subwoofers are placed in front of a stage, low-frequency noise radiates from the rear of their cabinets. Too much bass onstage is troublesome. It makes monitoring difficult. Achieving a proper mix is infuriating. And you waste energy by sending low frequencies in the wrong direction. The QSC KS Cardioid powered subwoofer uses manipulation of placement, delay, and polarity to redirect the low-frequency energy forward. Performers onstage experience 15dB less low-frequency output than those in front of the cabinet.
