Hi Canman
I have the M22's speakers,and I was worried about them being tipsy aswell,because I have a 18 month little boy.
So what I did was have the M22's on their stands,but also had them wall mounted to the back of the speakers,so my little one can't knock them over. Works great,this is something you might want to consider,if you really want the M22's.Because they are worth considering.
