Vision Series
Compact Two-Way Speaker System
PA281
The PA281 is an extremely versatile wide-dispersion,
low-profi le, two-way loudspeaker system offering sub-
stantial power and value for a variety of professional
applications that include primary sound reinforcement
and supplementary fi ll for larger systems. Its compact
size makes it ideal for low visibility column, side wall,
or under balcony mounting.
The high-frequency section is a constant directiv-
ity horn loaded to a 1-inch compression driver with
a 1.75-inch diaphragm assembly for smooth, wide
dispersion. The low-frequency transducers are two 8-
inch carbon fi ber woofers suitable for diffi cult climatic
environments.
The system includes a high-level crossover net-
work that features markedly lower (than conventional)
induction values in series with the woofer. We call
this innovation LICC (Low Impedance Compensated
Crossover). The benefi t is delay reduction, reduced
phase shift and superior transient response. Dynamic
high-frequency driver protection is accomplished with
a fast-response fi lament resistor, chosen to comple-
ment the power curve of the driver.
The Mackie PA281 is a part of the VISION family of
loudspeaker products including full-range, cost-effective
two-way loudspeakers and complementary subwoofer
cabinets. These enclosures have a trapezoidal foot-
print for easy array confi guration. All enclosures are
constructed using 19 mm void-free, birch plywood
and fi nished with a scratch-resistant black coating.
Transducer components are protected from the envi-
ronment by a heavy gauge metal grille. The VISION
products are eminently suited for fi xed installation,
ready for suspension via built-in M10 inserts with
metal reinforcement and forged shoulder eyebolt hard-
ware. The PA281 also includes M8 inserts.
This Mackie product is covered by an exclusive, one-
time, NO FAULT repair policy in addition to a fi ve year
limited warranty.
