Mackie PA151 Specifications

Vision Series
I
The PA151 is an extremely versatile, wide-disper-
sion, two-way loudspeaker system offering substantial
power and value for a variety of professional applica-
tions that include primary sound reinforcement and
supplementary fill for large speaker systems.
I
The low-frequency transducer is a 15" woofer with a
sturdy 3" voice coil that can provide excellent low-fre-
quency response along with high power handling. The
high-frequency section combines a modified constant
directivity horn having a 1" exit and coupled to a com-
pression driver with a 1.75" diaphragm assembly.
I
The system includes a high-level crossover network
that features markedly lower (than conventional)
induction values in series with the woofer. We call this
innovation LICC (Low Impedance Compensated
Crossover). The benefit is delay reduction, reduced
phase shift and superior transient response. Dynamic
high-frequency driver protection is accomplished with
a fast-response filament resistor, chosen to comple-
ment the power curve of the driver. The PA151's
crossover is easily bypassed for bi-amp or tri-amp
(with the PA180SW) operation via an installer-accessi-
ble changeover block. Back panel indicators display
the current system setting.
I
The Mackie Industrial PA151 is a part of the VISION
family of loudspeaker products including full-range,
cost-effective, two-way loudspeakers and complemen-
tary subwoofer cabinets. The two-way enclosures have
a trapezoidal footprint for easy array configuration. All
enclosures are constructed using 19mm void-free,
birch plywood and finished with a scratch resistant
black coating. Transducer components are protected
from the environment by a heavy gauge metal grille.
The VISION products are eminently suited for fixed
installation, ready for suspension, via built-in M10
inserts with metal reinforcement and forged shoulder
eyebolt hardware.

This Mackie Industrial product is covered by an
exclusive, one-time, NO FAULT repair policy in addition
to a five year limited warranty.
