The Yamaha BWS50-190 is a wall-mounting bracket designed for the MSR100 speaker, but accommodates speakers from other manufacturers as well. The sturdy unit is 7-7/16" long and weighs over 2.5lbs. The BWS50-190 features collars on both ends of the bracket allowing 360deg. rotation. Additionally, the joint in the shaft of the bracket swivels over 200deg. in 6deg. increments. This flexibility of positioning allows many possible mounting angles in order to attain the desired coverage.
