The QSC AcousticPerformance™ AP-5122
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-5122 uses a high power-capacity,
76mm (3-inch) diaphragm compression
driver and combines it with a 305mm
(12-inch) woofer to deliver exceptional
full bandwidth reproduction.
The uniform power-response of the
AP-5122 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-5122 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-5122 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-5122 enclosure features M10
mounting points for suspension via eyebolts as well as mount points for an
optional yoke bracket.
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-5122 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.
