AcousticPerformance™ Series Loudspeaker Application Guide 3
AP-5152
A 15-inch two-way loudspeaker with 75° coverage. It can be operated in either
full-range passive mode (using the internal passive crossover) or active (bi-amped,
with an active crossover). Bi-amped, the LF and HF drivers both have 8-ohm
impedances. In full range, the system also has an 8-ohm impedance.
The trapezoidal enclosure has no handles but does have M10 threaded inserts that
make it suitable for flying or yoke mounting in a permanent
installation.
• HF: Compression driver with 76 mm
(3 in) voice coil
• LF: 15 in driver with 76 mm (3 in) voice
coil
• Max continuous SPL at 1m: 123 dB
• Recommended crossover: 950 Hz, 48 dB/
oct slopes
• Intrinsic Correction™ available in select QSC
processors
AP-4122m
A 12-inch two-way coaxial
loudspeaker with 90° coverage. It has
a 4-ohm impedance and can only be
operated as a full-range loudspeaker
with an internal passive crossover.
The enclosure has a handle on one end
and a 35 mm pole socket on the other. One
side is angled at 40 degrees and another at 60
degrees, so the loudspeaker is very suitable for
stage monitoring, both upstage and downstage. The
pole socket has Tilt- Direct™, which allows the user to
mount the loudspeaker on a pole either straight upright
or with a 7.5-degree downward tilt. The tilt is useful for directing sound from high
pole-mounted loudspeakers down toward the audience instead of projecting it over
them.
The low- and high-frequency drivers are coaxial to each other, so imaging is
completely independent of the enclosure’s orientation.
• Compression driver with 45 mm (1.75 in) voice coil, coaxial with 12 in driver
with 76 mm (3 in) voice coil
• Max continuous SPL at 1m: 123 dB
• Recommended crossover: 950 Hz, 48 dB/oct slopes
• Intrinsic Correction™ available in select QSC processors
