An ultra-compact 12-inch bandpass sub with casters included and two pole sockets.
The KS112 is the ultra-compact model in QSC's KS Series, built for installation and highly portable rigs. A single 12-inch long-excursion driver works in a 6th-order bandpass design, powered by a 2000 W peak Class D module. QSC Intrinsic Correction tuning and loudspeaker management handle the voicing and protection.
The cabinet is premium 15 mm birch with a painted finish, and four low-noise casters come in the box. Two M20 threaded receptacles give a solid, wobble-free connection to a speaker pole whether the sub stands upright or lies on its side.
Two locking XLR/¼ inch combo inputs pass through to two XLR loop-thru outputs, so a pair of tops connects straight from the sub. An optional KS-LOC cover locks the controls in fixed installations.
