It's ShowTime. The signature sound of Bose Professional takes center stage with the ShowTime SK12. Specially tuned for KTV (karaoke) applications, the SK12 is a 12-inch full-range indoor loudspeaker that combines exceptional performance with everyday reliability. Designed with installers in mind and singers at heart, ShowTime brings concert-quality sound to KTV rooms and karaoke applications. With a frequency range of 45 Hz–20 kHz and 131 dB max SPL, the powerful 12-inch woofer and Bose Professional EMB2S compression driver provide exceptional vocal clarity and tonal consistency. The SK12 features precise frequency shaping to deliver a tailored midrange boost—enhancing vocals and making every note easier to sing. Engineered with professional-grade materials and components, ShowTime’s rear-ported design creates extended bass response and smooth, balanced sound. Two Neutrik® speakON® NL4MP connectors ensure fast, secure and reliable connections to amplifiers. M8 threaded inserts allow for flexible mounting either vertically or horizontally, and a convenient pole-mount adapter makes portable use a breeze.
