QSC KSUB Active Subwoofer

The K Series has been primarily designed for portable audio reinforcement. This includes a variety of uses in reinforcement for entertainers and presenters. For extra low-frequency extension and enhancement, the KSub is perfectly matched to the rest of the K Series. The K8, K10 and K12 all have a selectable high-pass filter for use with the subwoofer. The KSub includes a fixed low-pass filter so it will accept full-range input. The KSub has four large casters for maximum portability. The pole socket on the top of the enclosure is fitted with an M20 threaded insert. The included speaker pole screws into the socket for a secure fit.
