This is a great wall mounts even for drywall. Brackets are very simple and easy to put up.  However, the Bose  Cenimate II system puts a lot of weight on them and they look like they could fall out of the wall.  But, the brackets hold up very well. The trick is to cut a hole just right for the speaker wire to come through the wall.  But, not too big so you cannot screw the bracket into the wall because it will break off.  the UBs can grip into the drywall.  But, the Cenimate IIs have this humungous speaker wire connection, that attaches to the speaker itself and the  that is over 2 inches long and a quarter inch thick.  Measure twice cut once or your wall will look like Swiss cheese,
