The MB12 and MB12 WR low-frequency loudspeakers are designed to provide bass augmentation for Bose LT arrays and other subwoofer applications. The compact 1 x 12" (305 mm) configuration allows minimal-height arrays when used with LT mid/high loudspeakers. Bose Modeler® tools and optional rigging hardware make directional bass arrays easy to design and install using MB12 loudspeakers.
