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.
To assist in successful systems integration,
complete EASE, CF2, CAD, and BIM files are
available for online download at qsc.com.
