Step up the low-end of any portable PA with the CL212S — a passive subwoofer driving a pair of 12" long-excursion woofers in a tuned bass-reflex cabinet for deep, articulate sub-bass response. The dual-driver configuration delivers high SPL with the kind of tight kick-drum punch and rolling basslines that make a room move, while the high-impact birch plywood cabinet with reinforced corners and recessed steel grille is built to live in flight cases and survive the road. A 35 mm pole-mount socket on top lets you stack a satellite top directly above for stage-friendly deployment, and parallel Speakon plus 1/4" jack inputs make daisy-chaining a second cabinet effortless. Mobile DJs, club installers, weekend warriors and event-rental operators — this is the sub that anchors the rig.
