Bring authoritative low end to your KC12 column system with the QSC KC12S-WH Subwoofer Module. Designed specifically for the KC12 Active 3-Way Column Loudspeaker System, this QSC pro subwoofer module delivers focused bass extension that tightens low-frequency response and improves overall clarity — a critical benefit for live sound, corporate AV and monitoring applications used in security and surveillance suites.

The KC12S-WH (K Class series, Mfr. PN KC12S-WH) pairs mechanically and sonically with KC12 loudspeakers to provide a consistent tonal match and simplified installation. Its white finish and compact footprint allow discreet placement in front-of-house, conference rooms or control rooms without distracting from the environment. By reinforcing low frequencies, the subwoofer enhances speech intelligibility and musical impact—important for paging, monitoring and recorded-audio playback in surveillance or monitoring installations.
