Bose Professional column line arrays are specially engineered to excel in speech intelligibility and musicality, even in acoustically challenging spaces. Their modular design allows easy stacking of up to three linked modules. Lengthening the array results in extended coverage and lower-frequency control. These arrays are available in both powered and passive configurations and come in black or white versions.
Our column line arrays create a vertical sound beam that covers the entire audience while reducing disruptive echoes that compromise clarity. The outcome is consistent front-to-back sound propagation, and the wide horizontal coverage delivers consistent tonality across the entire audience, ensuring each listener enjoys the same sound experience.
The MSA12X is our flagship model, a powered beam-steering loudspeaker that allows mounting at varying heights and precisely aiming it electronically. It also outperforms passive models with its dual-beam functionality, enabling the vertical sound beam to be split into two, providing simultaneous coverage for separate areas such as the main floor and a balcony.
Our passive column line arrays offer comparable speech intelligibility and modularity, providing an alternative when a powered model isn't practical. The MA12EX delivers an extended frequency response and coverage for vocal and music reinforcement for indoor or outdoor applications, whereas the MA12 is designed for vocal-only indoor applications.
