I now need to wallmount my rear M22's and was wondering what is the best possible one to get. I have looked at the btech BT77 but since the side walls of the speaker aren't parallel i don't think they will work. I don't want to screw into the actual speaker. I was also looking at the BT3 but I don't know if they are strong enough for the M22's. Can someone suggest what they use or what they know will work. Thanx in advance.
