User manual MACKIE ART300 DATASHEET

[. . . ] Art Series I The same careful acoustic design and advanced materials used in the ART active speakers have been utilized in the ART300 passive speaker. Combining high efficiency, high power handling and excellent sonic performance, the ART300 provides practical solutions for permanent installation applications.

The drivers shall be crossed over at 1. 8kHz by a 2-pole, passive network that contains equalization for the constant directivity horn and shall present a nominal 8 load to the power amplifier. When measured (500Hz­16kHz) the directivity factor shall be at least 10. 0. The loudspeaker shall be capable of operating continuously with a pink noise signal delivered at 300W RMS. It shall produce at least 101dB SPL (300Hz­3kHz) at 1m with an input of 1W RMS. Its peak power handling capability shall not be less than 1200W peak, producing 132dB SPL (1m, anechoic). The nominal frequency response of the system shall be 195Hz­17kHz ±3dB. [. . . ] 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.
