The BOSE's PANARAY MA12EX modular vertical line-array loudspeaker has twelve 2.25" mid/high-frequency drivers installed in a vertical line array to give excellent vocal intelligibility in acoustically challenging spaces. This passive speaker offers a wide horizontal coverage with weather-resistant components, and a nominal coverage of 160 x 20°. The modular design allows for the stacking of numerous enclosures in a line array configuration for improved vertical pattern control and reduced undesired floor/ceiling reflections.
