The AudioCenter SA310 Plus is a compact 10-inch active DSP-controlled loudspeaker for portable PA systems, live performance, DJ use, presentations, houses of worship, monitoring, and fixed installations. It combines a customized 10-inch low-frequency driver, a 1-inch-exit high-frequency driver, Class-D amplification, Bluetooth, and rear-panel LCD DSP control in a CNC-machined plywood enclosure.
AudioCenter publishes a 52 Hz–20 kHz frequency response, 80° horizontal by 50° vertical coverage, and calculated output of 124 dB continuous and 130 dB peak. MUSIC, FLAT, SPEECH, and W/SUB presets allow the loudspeaker to operate as a full-range main, speech cabinet, floor monitor, or top box with a subwoofer.
