they are 125wts at 8ohm??? more than likely so, but if they were 125wts at say 4ohm, then the 770 would be way too powerful.

even if they are 8, I would recommend either adjusting the surrounds down a few db or just being careful not to blast it. while surrounds dont get much sound, they do get that occasional loud crack or boom which is a lot of energy for them to handle going from nothing.

on the other hand if you do ever damage them, that will "force" you into getting different ones. :-)
