Bose Professional MA12EX Modular Column Array Loudspeaker
Description
The Bose Professional MA12EX is an extended-range modular column array loudspeaker designed for acoustically demanding indoor and outdoor applications. It features twelve 2.25-inch high-excursion, weather-resistant drivers arranged in Bose Professional’s Articulated Array® design, providing wide 160° horizontal coverage with controlled vertical dispersion.
With a frequency response of 75 Hz–13 kHz (±3 dB), the MA12EX delivers full-range speech and light music reproduction without requiring a separate bass loudspeaker. Its narrow vertical pattern helps reduce unwanted floor and ceiling reflections while providing consistent sound throughout the listening area.
The modular design allows multiple MA12EX loudspeakers to be stacked in single-, double-, or triple-module configurations for greater vertical control and increased throw distance. With an IPX5-rated weather-resistant construction, the MA12EX is suitable for houses of worship, restaurants, retail spaces, auditoriums, transportation facilities, gymnasiums, recreation areas, atriums, malls, and other indoor or outdoor installations.
