The Bose Professional MSA12X powered beam-steering array loudspeaker is specially engineered to excel in vocal intelligibility and musicality, even in acoustically challenging spaces. Twelve processed and amplified transducers create a precise vertical sound beam that covers the entire audience while reducing disruptive echoes that compromise clarity. The result: a consistent front-to-back sound without mechanical aiming or angling brackets.

The MSA12X goes beyond conventional loudspeakers 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. The articulated transducer configuration provides 160° horizontal coverage, delivering consistent tonality across the entire audience space, ensuring each listener enjoys the same sound experience.

The install-friendly modular design of the MSA12X allows easy stacking of up to three linked modules. Lengthening the array results in extended coverage, lower-frequency control, and improved dual-beam functionality—without custom ordering or oversized shipping boxes. The array’s beam-steering capability also allows you to mount it at varying heights—not just ear-level like conventional column arrays. Plus, the Dante^® network interface and ControlSpace ecosystem integration ensure seamless connectivity and system control.

Features

• 12 × 2.25-inch independently controlled and amplified transducers with frequency response from 75 Hz to 18 kHz create a vertical sound beam that is electronically steered for precision aiming to cover the entire audience area, while reducing disruptive echoes that may compromise clarity — without the need for mechanical aiming or angling brackets.
• Integrated DSP and 600 watts (12 × 50 W) of amplification makes the MSA12X a self-powered and self-processed loudspeaker solution without the requirement for a standalone amplifier or loudspeaker processor.
• Dante^® digital audio network interface provides one network cable connection for audio source and system control. Send digital audio to the MSA12X and use the same connection for ControlSpace network integration, enabling control, monitoring, and beam preset recall from ControlSpace-compatible processors, end-user controls, and third-party control systems. A line-level input is also provided for local analog source connection.
• Flexible, modular design allows the simple creation of larger vertical arrays by stacking one, two, or three modules without custom parts, ordering, or oversized shipping boxes. Select from just two models — white or black — and paint them if needed. You gain extended coverage, improved lower frequency control, and dual beam functionality.
• Articulated array transducer configuration provides 160° horizontal coverage delivering consistent tonality across the entire audience space, ensuring each listener enjoys the same sound experience.
• All brackets and interconnect cabling included — no extra parts to order.
