Bose SK12 Surface Mount Speakers

ShowTime SK12 is a 12-inch full-range passive loudspeaker for indoor entertainment spaces where music plays loud, vocals need presence, and systems have to meet practical performance and budget requirements. Designed for bars, lounges, restaurants, private rooms, KTV/karaoke spaces, and small live-music applications, SK12 delivers the output and tonal character needed to keep guests engaged. Powered by a 12-inch woofer and Bose Professional EMB2S compression driver, SK12 combines extended low-frequency response with clear vocal presence and smooth, balanced sound. A rear-ported enclosure delivers rich bass, and 90° × 60° rotatable coverage supports horizontal or vertical placement. Two Neutrik speakON NL4MP input and loop-through connectors, M8 threaded inserts, and an available pole-mount adapter or pan-and-tilt bracket give integrators practical options for permanent installations or flexible entertainment setups.
