I The PA151 is an extremely versatile, wide-dispersion, two-way loudspeaker system offering substantial power and value for a variety of professional applications 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-frequency response along with high power handling. The high-frequency section combines a modified constant directivity horn having a 1" exit and coupled to a compression driver with a 1. 75" diaphragm assembly.

Architects' and Engineers' Specifications
The two-way loudspeaker system shall be self-contained and consist of the following components: (1) a 15-inch, lowfrequency driver; (2) a high-frequency section consisting of a constant-directivity horn and compression driver; (3) a twoway crossover network; (4) a vented enclosure. The low-frequency transducer shall be a cone type loudspeaker having a cone diameter of at least 15 inches (380mm). Sensitivity shall be at least 99dB when measured at 1m with an input of 1 Watt and have a power rating of at least 250 Watts (AES), 1000 Watts peak. The high-frequency section shall have a compression driver with a diaphragm of at least 1. 75 inches (44mm) in diameter. It shall be connected to a constant-directivity horn having a throat diameter of at least 1 inch (25mm) and a nominal coverage pattern of 90° horizontal by 70° vertical. Sensitivity shall be at least 107dB when measured at 1m with an input of 1 Watt and have a power rating of at least 35 Watts (AES), 140 Watts peak. 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. The high-pass section of the network shall be equalized to optimize the performance of the constant-directivity horn. A dynamic high-frequency protection circuit based on a low-value, low-mass filament resistor shall limit the current available to the compression driver.

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.
