Bose Professional MA12EX Modular Column Array Loudspeaker (Each)

The Bose Professional MA12EX is an extended-range modular column array loudspeaker designed to deliver exceptional vocal intelligibility in acoustically demanding indoor and outdoor environments. Featuring wide 160° horizontal coverage and weather-resistant construction, it is well suited for spaces that require even sound distribution with minimal visual impact.

This loudspeaker uses a modular line array design with twelve full-range drivers arranged vertically to provide controlled vertical coverage while maintaining broad horizontal dispersion. Multiple MA12EX modules can be stacked to increase throw distance and coverage consistency in larger venues.

Engineered for permanent installations, the MA12EX supports a wide range of applications including houses of worship, auditoriums, transportation facilities, and public spaces. Optional mounting accessories and transformer options allow flexible system design and integration into distributed audio systems.
