Product Description

Ksub__17211_zoomKsub on casters from northernbeachesspeakerhirexl_3_qscksub
Delivering 1000 watts of continuous power and 2000 watts peak, the QSC KSub extends your sound reinforcement system’s bass range down to a chest-thumping 44 Hz. The KSub is plenty powerful for DJ rigs, pushing out a thundering 130 dB maximum SPL, while its attractive housing and small footprint make it perfect for houses of worship or upscale performance venues that need extra low-end punch in a low-profile cabinet. Plus, with four built-in casters and ergonomic handles for easy load-in, it’s ideal for mobile PA setups. The KSub is stackable for use in larger venues or outdoor special events that require multiple subs — and at just 14″ x 26″, a KSub can sit on its long side to fit under a stage riser in a small club or bar installation. The perfect match for QSC’s K Series full-range loudspeakers, the powerful, flexible, and professional-looking KSub delivers maximum bang-for-buck among QSC’s subwoofer offerings.
