Last night I went to perch my QSC KW122s on the poles and the whole cup assembly crushed into the cabinet. The socket is mounted on a board that is lightly glued and fastened with what looks like a few staple sized tacks. I don't have time to even wait for warranty - so I'm fixing myself with wood glue. When dry, I'll drill 4 holes through cabinet and mounting board and fasten with bolts and lock nuts. I plan to add the extra bolts to my other KW122 as well to prevent this from happening again. Luckily no audience members were injured but this could be dangerous, so if you own these - be aware!
