QSC AP-4122m

  • $1,220.00


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.

To further enhance system performance and speed of install with optimum result, proprietary Intrinsic Correction™ tunings are obtainable via Q-SYS networked audio processing platforms, including CXD and PLD amplifiers for a complete QSC systems solution.

The AP-4122m enclosure is of 15mm Baltic Birch plywood construction, designed for versatile deployments. The multipurpose enclosure features both 60° and 40° angles for use as floor monitors, M10 mounting points for suspension via eye-bolts or optional yoke bracket, top handle, and a tilt direct pole cup.

Presenting a clean, unobtrusive look, AcousticPerformance grilles are unadorned eliminating the need to cover-up logo treatments which can be difficult to hide or remove. The grille is lined with acoustically transparent backing to maintain the enclosure’s professional appearance. The AP-4122m is available in black (RAL 9011) finish.

The recessed input cup features two NL4 connectors for convenient input and pass through.

  • 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
