The SCS Sealed Cardioid Series of Powered Sub-Bass loudspeakers are designed to extend the low-frequency response, projection and precise directional control of CLA, HLA, and ULA systems. Each sub-bass system has two forward-facing drivers and a rear cancellation driver. Onboard power and DSP processing are by Powersoft.

SCS subwoofers are available in four driver configurations: (3)x12″, (3)x15″, (3)x18″, and (3)x21″

The SCS-312 is a self-powered cardioid sub-bass loudspeaker, designed to match the superb transient response of a CLA or HLA Hybrid Line Array.  It extends system low-frequency response, projection and directional control to 45 Hz.

Three 12-inch long-excursion drivers are employed in a cardioid configuration using on-board Powersoft DSP and amplification.  The drivers have (.7Q) sealed enclosures for optimum transient response.
