Product Description

For extra low-frequency extension and enhancement, the dual 12 inch QSC KSUB Powered PA Subwoofer 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. Constructed of premium birch, the QSC KSub includes high-quality, low-noise casters and a threaded pole receptacle for a positive, wobble free connection to a threaded speaker pole (included).
