Bose Professional MA12 Modular Column Array Loudspeaker
Description
The Bose Professional MA12 is a modular column array loudspeaker designed for clear, intelligible sound in acoustically demanding indoor spaces. It features twelve 2.25-inch mid/high-frequency drivers arranged vertically to provide wide horizontal coverage with controlled vertical dispersion.
The MA12 delivers 145° horizontal × 20° vertical nominal coverage from a single module, helping reduce unwanted floor and ceiling reflections. Its modular design allows multiple MA12 loudspeakers to be stacked together for increased vertical control and greater throw distance.
Designed primarily for speech reproduction, the MA12 is suitable for houses of worship, auditoriums, transportation facilities, restaurants and bars, gymnasiums, atriums, malls, and multipurpose spaces. For full-range music performance, Bose recommends pairing the MA12 with a compatible modular bass loudspeaker such as the MB4, MB12, or MB24.
