Bose Professional Modular Column Array Loudspeaker | Model: MA12

Product Description

The Bose Professional MA12 Modular Column Array Loudspeaker is a professional column-array loudspeaker intended to deliver clear sound over distance while controlling where much of that sound goes. A column array uses several drivers arranged vertically. In simple terms, this shape can reduce wasted energy toward ceilings and floors and put more useful sound toward the audience, which is valuable in reverberant rooms where reflections make speech difficult to understand. The slim profile of the MA12 can also integrate more discreetly into architecture than a conventional wide loudspeaker enclosure.

Its published frequency performance is 100 Hz – 16,000 Hz. The maximum output specification is 113 dB continuous, 119 dB peak. Published coverage information of 145° horizontally and 20° vertically helps the system designer aim sound toward occupied seating. These figures are design tools, not a guarantee that a difficult room will become perfect; acoustic modelling, mounting height, delay, equalization, and the number of arrays still matter.

The MA12 should be installed as part of a professionally engineered system with suitable amplification, processing, mounting hardware, and safety attachment. The enclosure dimensions are 38.8 in × 4.2 in × 5.0 in (984 mm × 105 mm × 128 mm), and the listed net weight is 19.0 lb (8.5 kg). For powered or beam-steering models, network setup and control software are also part of commissioning; for passive models, amplifier selection and protective filtering are central. Careful alignment can improve speech intelligibility and make level changes from front to back less distracting.

The MA12 is well suited to worship spaces, lecture halls, auditoriums, terminals, atriums, and other rooms where speech must remain understandable without visually dominating the architecture. It can also support music, but the required low-frequency extension and overall output should be evaluated for the program. Select this product when controlled coverage and a narrow visual profile are more important than simply choosing the smallest or loudest loudspeaker. Final array quantity, aiming, beam settings, and subwoofer support should be confirmed for the actual venue.

Suitable Use Scenarios

• Houses of worship, lecture halls, and auditoriums where spoken words must remain clear over distance
• Architecturally sensitive rooms that need a slim loudspeaker profile and controlled vertical coverage
• Transport terminals, atriums, and public spaces with reflective surfaces and challenging acoustics
• Performance and presentation systems that need focused sound directed toward listeners rather than ceilings and floors
• Large meeting or assembly spaces where consistent level and intelligibility are more important than visible loudspeaker size
