The Bose Professional MA3 Micro Array set of 4 includes four compact, passive modular loudspeakers designed to deliver clear speech and music reinforcement in permanent indoor installations. Ideal for houses of worship, multipurpose spaces, corporate environments, educational facilities, government buildings, and hospitality venues, the MA3 provides a visually discreet sound reinforcement solution for acoustically challenging environments. Its modular design allows the four loudspeakers to be combined into suspended or wall-mounted arrays, with adjustable splay angles that help direct sound toward the listening area while minimizing reflections from ceilings and other surfaces.
Each MA3 module features four 2.25" woofers and a 1" compression driver, providing 50W continuous and 200W peak power handling with a 16Ω nominal impedance and 100° horizontal x 5° vertical nominal coverage pattern per module. An integrated passive 2-way crossover and pluggable Euroblock connector simplify system wiring, while the built-in quick-pin attachment system allows multiple modules to be joined into a cohesive array. Bose Professional loudspeaker EQ presets are available for additional system optimization but are not required.
Featuring compact white ABS enclosures and powder-coated steel mesh grilles, the MA3 loudspeakers blend into architecturally sensitive interiors without compromising sound coverage flexibility. The optional MA3SB Suspension Bracket supports flown installations, while the MA3WB Wall-mount Kit provides wall-mounting capability. The optional MA3PBB Pullback Bracket Kit offers additional adjustment for suspended arrays. All mounting accessories are sold separately.
The set includes four MA3 loudspeakers, four pre-wired Euroblock connectors, and two inter-module connection plates. The modular format allows integrators to configure the four loudspeakers according to the coverage requirements of each installation.
