■ The model PACX81 (black) and PACX81W (white) are
professional full-range, ultra-compact coaxial loudspeaker systems providing wide bandwidth and light
weight in a low profile enclosure. The coaxial configuration of the transducers in the PACX81 provides an
ideal acoustic point source, yielding smooth frequency
and phase response throughout its coverage pattern.
The asymmetric cabinet design allows multiple applications including use as a floor or ceiling monitor.
■ The coaxial speaker consists of an 8" high-output
carbon fiber woofer with a 2" voice coil, combined with
a back-mounted titanium dome high frequency transducer suitable for difficult climatic environments.
■ 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 complement the power curve of the driver.
■ The Mackie Industrial PACX81 is a part of the
VISION family of loudspeaker products including fullrange, cost-effective, two-way loudspeakers and complementary subwoofer cabinets. These enclosures
have a trapezoidal footprint for easy array configura-
tion. All enclosures are constructed using 19mm voidfree, birch plywood and finished with a scratch-resistant black or white coating. Transducer components are
protected from the environment by a heavy gauge
metal grille with open-cell poly fiber backing. 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. The PACX81 also includes M8 inserts.
■ This Mackie Industrial product is covered by an
exclusive, one-time, NO FAULT repair policy in addition
to a five year limited warranty.
