The Bose MA12 WHITE is a Panaray Modular Line Array Loudspeaker. Wide 145° horizontal coverage. Designed to provide outstanding vocal intelligibility in acoustically demanding spaces. Slim column enclosure blends with almost any décor. Twelve 2.25" (64 mm) Drivers mounted in a vertical line array deliver wide horizontal coverage with narrow vertical pattern control. Modular Design Allows stacking of multiple enclosures in a line array configuration to provide increased vertical pattern control which improves “throw” distance and reduces unwanted floor/ceiling reflections. 145° Horizontal X 20° Nominal Coverage Coverage for a single module. Vertical coverage varies with the number of modules stacked in the line array configuration. Mid/High Configuration Allows bass management and design flexibility. Use with Bose MB4, MB12, or MB24 modular bass loudspeakers for full-range reinforcement. Optional Brackets Allow easy installation of single-, double- or triple-stack line array modules.
