QSC AP-4122M
12" High Power Coaxial Installation Loudspeaker

OUR PART #  AP-4122M


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.

QSC AP-4122m Features:

  • DMT™ (Directivity Matched Transition) ensures smooth,coherent power response across the listening plane
  • 90 degree conical coverage matches the natural coverageof the 12-inch woofer at the crossover point for consistent power response
  • Coaxial mounted 1.75-inch voice coil compression driverfor outstanding high-frequency performance
