The white Panaray MA12 Modular Vertical Line-Array Loudspeaker from Bose Professional features twelve 2.25" mid/high-frequency drivers mounted in a vertical line array designed to provide outstanding vocal intelligibility in acoustically demanding spaces. With a nominal coverage of 145 x 20�, this speaker has a wide horizontal coverage with narrow vertical pattern control. The 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. This slim column enclosure blends with most decor.
