The QSC AcousticPerformance AP-4122m is a professional, two-way, fullrange loudspeaker ideal for a variety of portable and installed sound reinforcement applications requiring high power, wide coverage and compact size. The AP-4122m uses a 305mm (12-inch) woofer with 64mm (2.5-inch) voice-coil and a coaxially mounted high power-capacity, 44mm (1.75-inch) voice coil compression driver to deliver exceptional full bandwidth reproduction. The uniform power-response of the AP-4122m is a result of DMT (Directivity Matched Transition), a design philosophy which matches the HF waveguide to the natural conical coverage of the woofer at the cross-over point. The result is a remarkably consistent coverage with smooth, accurate reproduction both on and off-axis.

• DMT (Directivity Matched Transition) in 2-way models ensures smooth, coherent power response across the listening plane
• 3” diaphragm compression driver (1.75" on AP-4122m) delivers a clean and powerful high frequency response
• M10 fittings and yoke mount fittings offer flexible deployment options for a variety of applications
• Pole cup (AP-5122m and AP-4122m)
• Two M20 pole attachment points on AP-212sw
• Clean industrial design with unadorned grilles complement most decors and settings
• NL4 Speakon connector (two on AP-4122m and AP-212sw) and covered barrier strip terminals (except AP-4122m and AP-212sw)
• Bi-amp / passive switchable (passive only on AP-4122m), except AP-212sw subwoofer
• Constructed from 15-ply Baltic birch plywood (15 mm Baltic birch plywood on AP-4122m and AP-212sw)
• 16-gauge powder coated steel grilles
• Available in black (RAL 9011) and white (RAL 9010) (black only on AP-4122m and AP-212sw)
• Complete EASE, CAD & BIM information available online
