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

Architects' and Engineers' Specifications
The two-way loudspeaker system shall be self-contained and consist of the following components: (1) an 8 inch, twoway coaxial loudspeaker; (2) a two-way crossover network; (3) a vented enclosure. The low-frequency section of the transducer shall be a cone type loudspeaker having a cone diameter of at least 8 inches (200mm). It shall have a titanium voice coil of at least 1 inch (25mm) in diameter. The system shall be crossed over by an internal, highlevel, passive network having a response of 12dB/octave. The lowpass section of the network shall have minimum inductance in series with the low frequency driver component. A dynamic high-frequency protection circuit based on a low-value, low mass filament resistor shall limit the current available to the high-frequency driver component. A switch shall be provided to disconnect the crossover network, but not the high-frequency protection circuit, from the drivers to allow bi-amp operation. The enclosure shall be a vented design with an internal volume of at least 0. 53 cu. It shall be constructed using 0. 75 inch (19mm), voidfree birch plywood and finished with black, scratch resistant paint.

Mackie Designs continually engages in research related to product improvement. New material, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current Mackie Industrial product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
