The pair of black 8” High Power Ceiling Subwoofer Assembly from Behringer is designed for a wide variety of fixed-installation applications. Delivering deep, powerful lows that complement full-range ceiling loudspeakers, the subwoofer is suitable for distributed systems in conference centers, hotels, casinos, and other venues that require rich, full reproduction of music, voice, and AV sources.
Featuring an 8” (203.2mm) woofer with 160W maximum power capacity, the high-performance ST208S system accurately reproduces demanding low-end material for a clean and full sound. Operating mode and power are selected with a front-mounted 5-position rotary switch that sets the loudspeaker to operate either in low-impedance mode (8Ω) or at one of the supported wattages for operation at 70V (10, 20, 40, or 80W) or 100V (20, 40, or 80W). Overload circuitry is included to protect the loudspeaker from excessive peaks, thereby reducing the expense and complexity of including subwoofers in a distributed speaker system.
The ST208S Subwoofer is housed in a ported reflex back can that is constructed of rigid, zinc-coated steel for enhanced bass response. The 13.7" (347.9mm) cylindrical assembly is designed for easy blind installation in ceiling tiles using the C-ring support bars (included) and backing plates, and features a seismic restraint that secures it to the building’s structure via a steel cable. The amplifiers are connected via a 4-pole Euroblock connector and an extended black grille with smoked-chrome rim replaces the standard ceiling-fixture trim ring, giving the subwoofer a classy look that makes it suitable for highly finished spaces.
