The Bose 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.
The enclosure is constructed of void-free, exterior grade Baltic birch plywood with extensive internal bracing. The enclosure interior has been treated with wood sealer and the exterior finished with a two-part spray polyurethane coating to resist weather elements and scuffing. The enclosure is covered by a 16-gauge perforated stainless steel grille with powder-coated finish and backed with an open-cell foam. The loudspeaker can survive water incursion consistent with the IEC 529 IPX5 rating. The enclosure has sixteen (16) stainless steel threaded inserts (4 each: top, bottom, sides) that accept standard SAE 3/8"-16 rigging hardware.
