We are moving to a new house in the next couple of weeks and are creating a room that will be 7.1. We are bringing our five speakers from the old system (all great speakers) but need to decide what to do for the new ones. I was looking at the RM-8's and wondered if those would be good mid surround speakers. Obviously they have great reviews but worried because of the wide dispersion and how that would work from where they supposed to sit. If these aren't the best, what is a good speaker for this in the price range of 100-150 for a pair.
