The MA12 is a versatile vertical line array speaker featuring twelve 2¼‑inch drivers that deliver wide 145° horizontal coverage and controlled vertical dispersion. Its modular design allows multiple enclosures to be stacked, extending vertical coverage, improving “throw” distance, and minimizing unwanted floor and ceiling reflections.

The mid/high configuration provides flexible bass management, and for full-range sound, it can be paired with Bose Professional MB4, MB12, or MB24 modular bass units. Optional brackets simplify installation of single, double, or triple-stack line array setups, making the MA12 ideal for both portable and installed sound reinforcement applications.
