Oh, the receiver is behind doors, at least.
The problem is that the M80s are in the living room (18x19) where he plays, and the M50s are in the computer room/his room/something whatever it is where he currently sleeps (and plays). It's going to be hard to keep him away from them, and there's no where to have him play where there aren't speakers.
The M80s should be ok out in the open but having the M50s in his room is just asking for trouble. They are afterall in his room and I will bet he will soon be thinking everything in that room is fair game unless you have extra eyes or have cloned yourself; not even a video camera can help, by the time you get there the damage will be done. I guess you will have to spend equal amounts of time in the living room and the bedroom with constant reminders to him, eventually he won't touch anything, at least not until he gets to be a teen
