On 6 November 2026, Bose Professional introduced the MA3 Micro Array, a newcomer to its line of passive modular arrays. The brand is well established here with the MA12 and MA12EX, articulated columns used in fixed installation. The MA3 takes that principle and shrinks it to a very small module, aimed at spaces where a conventional loudspeaker would cause more problems than it solves.
A modular array that fits in your hand
Each module measures 138 by 288 by 206 millimetres and weighs 3.5 kilograms, in a white ABS enclosure with a steel grille. Modules snap together with a quick-pin system and form a single column. Shawn Watts, Bose Professional VP of Sales for the Americas, sums up the target in one line: “it’s compact, it’s affordable and it’s a one-person install.” The product is rated for indoor use only.
One module, five drivers
Inside each module, Bose fits a 1-inch compression driver and four 2.2-inch woofers, tied together by a passive two-way crossover at 1.8 kHz. Power handling is rated at 50 watts continuous and 200 watts peak, with a clear recommendation: a 70 Hz high-pass filter, minimum slope 24 dB per octave, to protect the drivers. Bose presets are available but not required, and connection is via a pre-wired Euroblock terminal.
Coverage is set at assembly
A single module covers 100 degrees horizontally and only 5 degrees vertically. That is the line-source principle itself: by stacking modules and adjusting the angle between them, you shape the vertical coverage, throw further or aim at a specific balcony. For a refresher, our feature on how a line-source PA really works sets the basics, and point source vs line array helps you decide by room. Speaker directivity and dispersion explain why such a tight vertical angle serves clarity in a lively space.
Install and accessories
The MA3 ships in one-module or four-module packs, with the Euroblock terminal and the inter-module connection plates. For rigging, Bose offers an MA3SB suspension bracket, an MA3WB wall-mount kit and an MA3PBB pullback kit. The whole thing plays it discreet: a thin white column that blends into the architecture rather than dominating the sightline. That is the deliberate trade-off of an install product, the opposite of big touring systems.
The numbers still missing
Bose has not published a frequency response, a maximum SPL or a price yet, and the data sheet remains preliminary. On a micro array meant for houses of worship, meeting rooms, museums or retail, it is precisely the achievable level and the price that will decide its place. We will wait for those figures before judging.
My take
The MA3 hits a precise market: chatty rooms where a big system would mostly do damage. A passive array that one person can hang and that disappears into the wall is exactly the reflex an integrator wants for a house of worship, a meeting room or a museum. The very tight vertical angle points the right way for intelligibility. What remains is the maximum SPL and the price, still missing from the sheet: on a format this small, that is where it all plays out.
