Review on Bose UB-20 Series II Speaker Wall Mount Bracket for CineMate and Lifestyle Speakers - Black (Not Compatible with Lifestyle 650) by Jessie Burgos

These are very stable brackets and worked well with my Bose Acoustimass 10 Series V surround speakers. My only concern was that the instructions were not clear on how to install them align the brackets with the speaker wire hole. I made a mistake on the first one and had to rework a bit instead of redrilling the 4 screw holes in the ceiling. Also, I'm a bit worried about the 4 plastic drywall anchors being so close together. This can weaken the drywall and eventually fail due to the weight of the speakers and brackets. A latch bolt and wing nut drywall anchor are stronger and allow for more flexibility in the speaker cable.
