loudspeaker
AP-5152
Features
• DMT™ (Directivity Matched 
Transition) ensures smooth, 
coherent power response 
across the listening plane
• 75 degree coverage of the 
axisymmetric waveguide 
matches natural coverage 
of the 15-inch woofer at the 
crossover point for consistent 
power response

construction
• 16-Gauge powder coated 
steel grilles 
• Clean industrial design with 
unadorned grilles compliment 
most decors and settings

The QSC AcousticPerformance™ AP-5152 
is a professional, two-way, full-range 
loudspeaker ideal for a variety of installed 
sound reinforcement applications requiring 
higher SPL output and a clean appearance. 
The AP-5152 uses a high power-capacity, 
76mm (3-inch) diaphragm compression 
driver and combines it with a 381mm  
(15-inch) woofer to deliver exceptional  
full bandwidth reproduction. 
The uniform power-response of the  
AP-5152 loudspeaker is a result of 
DMT™ (Directivity Matched Transition), a 
design approach that matches LF and HF 
coverage in the cross-over region. Another 
key to the extraordinary accuracy and flat 
power response of the AP-5152 is the 
axisymetric waveguide with uncompromised 
performance in both the vertical and 
horizontal axes. The result is remarkably 
consistent coverage and smooth, accurate 
reproduction on and off-axis. 
The AP-5152 may be used as a passive (fullrange) loudspeaker to minimize amplifier 
channel count or it may be bi-amplified for 
greater control and performance. To further 
enhance performance, bi-amp and fullrange tunings using QSC Intrinsic Correction 
techniques are available for Q-Sys and future 
QSC products. 
The AP-5152 enclosure features M10 
mounting points for suspension via eyebolts. 
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 also lined with 
acoustically transparent backing adding to 
the enclosure’s professional appearance and 
the AP-5152 is available in black (RAL 9011) 
and white (RAL 9010) finishes. 
To minimize impact and disposal fees at the 
job site, all AcousticPerformance loudspeakers 
are packaged in environmentally friendly, 
recyclable cartons.
