Yeah i think going with the 60 is the safer bet, I read a review on audioholics.com and the m80's were so powerful the 150 center had trouble keeping up, so he threw two 150 centers in the system, that would be awesome! My room isn't Huge so i'm sure the 60's along with the 150 will blow my paradigm system away, at least i hope they will. i haven't found any good reviews (professional) on the 60's like i have on the 80's.
