I just purchased a Yamaha rx-v2400 and I currently have a set of Bose 701 and 5.1 Yamaha cls 150 with a sw-4 subwoofer. I was wondering how the m60ti would compare with the Bose. I have an 18 x 16 room where I have mounted the surround speakers from the ceiling. What speaker system would Axiom recommend to match this system. Also could anyone explain what a presence speaker is?
