The MA12EX is a compact, high-performance line array speaker designed for wide horizontal coverage and precise vertical control. It features twelve 2¼‑inch full-range drivers arranged in a vertical array, delivering clear speech and music across a broad listening area.

Its modular design allows stacking multiple enclosures to extend vertical coverage, enhance “throw” distance, and minimize unwanted floor or ceiling reflections. Each module provides 160° horizontal coverage and approximately 20° vertical coverage, with actual vertical range adjustable depending on the number of modules used.

The MA12EX covers frequencies down to 58 Hz, enabling full-range sound without a separate subwoofer, though it can be paired with Bose Professional MB4, MB12, or MB24 modular bass units for extended low-end performance. Optional brackets make installation of single, double, or triple-stack configurations simple and flexible.
