ART300
Art Series
Two-Way Speaker System
 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 two-way design consists of a 12" woofer that
uses a massive magnet structure for accurate bass
reproduction and a CD horn loaded to a 1" exit
compression

ART300 Two-Way Speaker System Architects’ and Engineers’ Specifications The loudspeaker shall be a self-contained unit, housed in a vented, reinforced polypropylene enclosure and consisting of: (1) a 12 inch low-frequency, cone driver, (2) a 80° x75°, high-frequency, constant-directivity polynomial horn and horn-loaded, 1 inch compression driver, (3) passive crossover network. The drivers shall be crossed over at 1.8kHz by a 2-pole, passive network that contains equalization for the constant dire
