I currently have the following: AS-F2 (front) AS-C1 (center) S.5 (surround) S.5 (rear center) The S.5 are mounted 7 feet high and pointed down towards the primary listening area. They are leftover from my point 5 system. I was thinking about getting a pair of AS-R1 to replace the S.5 as surrounds. How do they sound and how much of an upgrade would they be? I thought about getting a third for the rear center also, but the rear center isn't used that often so I'd do that last. I couldn't find many reviews on the AS-R1, so please post them here!
