I totally agree with Mark and Wid. Your reason for eliminating the sub makes no sense if your reasoning is you want more bass out of the m60's. Are you sure you have your receiver set correct so your M60's are receiving the full frequency? Most people that listen to my m60's with no sub ask "Are you sure you turned off the sub?" Anyway, like Mark, I don't understand your reasoning. You say you want more bass for movies, so if you did infact find some mains that gave you the bass your looking for, it would be no different than a sub in the equation.
You would be better off adding the sub back, and just adjusting the volume to a level that won't disturb the neighbors/wife.
