Qsc Llc KC12S-BK Commercial Subwoofer

Product Description

The QSC LLC KC12S-BK is a commercial subwoofer designed to extend low-frequency output in professional audio installations. Subwoofers in this class handle bass reinforcement duties that full-range loudspeakers cannot cover on their own, delivering the lower end of the audio spectrum for speech, music, and entertainment applications. This unit is sold individually and is intended to be paired with a compatible equalization or signal-processing component as part of a complete system. Installation and commissioning are typically performed by a qualified AV systems integrator or commercial audio technician.

The KC12S-BK is suited for commercial audio environments where controlled, extended bass response is required. Typical applications include installed sound systems in venues such as houses of worship, restaurants, retail spaces, and performance facilities. This subwoofer is sold as a single unit (UOM: EA, QTY Per: 1) and must be ordered alongside compatible equalization or processing equipment to function as intended within a full-range system.
