SPEAKER PACX81 PACX81 Coaxial, Two-Way Speaker System 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 voice coil of at least 2 inches (50mm) in diameter. It shall present a nominal impedance load of 8Ω. The high-frequency section of the transducer shall be a dome tweeter. It shall have a titanium voice coil of at least 1 inch (25mm) in diameter. It shall present a constant-impedance load of 8Ω. The system shall be crossed over by an internal, highlevel, passive network having a response of 12dB/octave. The nominal crossover frequency shall be 1.3kHz. 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. ft. The vent shall be tuned to 60Hz. It shall be constructed using 0.75 inch (19mm), voidfree birch plywood and finished with black, scratch resistant paint. A model finished in white scratch-resistant paint shall be available from the manufacturer. It shall be an asymmetrically shaped trapezoid to facilitate various monitor and mounting configurations. A full size, detachable, perforated steel grille, finished in black scratch-resistant paint shall be provided. At least 8 reinforced threaded metal sockets (M10 & M8) for attaching mounting hardware shall also be provided. The overall dimensions of the enclosure shall not exceed 15 x 11.81 x 10.63 inches (381mm x 300mm x 270mm). Connections to the loudspeaker shall be Speakon® NL4 connectors. (continued Architects' & Engineers' Specs) The performance of the two-way loudspeaker system shall be as follows: long-term power handling, at least 150 Watts RMS; peak power handling, at least 600 Watts; frequency response, 100Hz-17kHz at -3dB; maximum SPL, 120dB (anechoic-1m); sensitivity, 92dB SPL (1W/1m anechoic); -6dB coverage, measured average 800Hz-16kHz, 110° horizontal by 110° vertical. The two-way loudspeaker system shall be a model PACX81 (PACX81W, white) manufactured by Mackie Industrial.

New material, produc- tion 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. ©1999-2001 Mackie Designs Inc.
