QSC AP-4122m AcousticPerformance Coaxial Loudspeaker
The AP-4122m is the multipurpose box in QSC's AcousticPerformance line, built with 60 and 40 degree monitor angles molded into the same enclosure that flies, poles, or yoke mounts, so one box covers stage monitor and fixed-install duty. A 12 inch woofer with a 2.5 inch voice coil is paired with a coaxially mounted 1.75 inch compression driver for DMT-matched, uniform 90 degree conical coverage that stays consistent on and off axis.
The 15 mm Baltic birch enclosure has M10 mounting points for eyebolts or the optional AP-YM12m yoke bracket, a top handle, and a tilt direct pole cup, with two NL4 Speakon connectors for input and pass-through. Intrinsic Correction tunings are available via Q-SYS and CXD/PLD amplifiers for a complete system.
