My daughter is off to college and I am putting together a system for her. Right now she is in a small studio apartment with a slight loft and ledge above the couch where she will watch tv. Of course like any young person, she will probably move a lot in the years to come so each location will have a different listening arrangement. I will probably get her the M3's with a 100 center for the front. Should I get her directs or quad poles for the rear given that she will move a lot?
