I just ordered new speakers to replace my front mains and center channel. I am replacing floorstanding Sony mains (SS-AV44) and the matching Sony center (SS-CN15) (these also match my Sony rears (SS-SR15), which are quite small). I am upgrading to Klipsch RF-3IIs and an RC-3II. Unfortunately, at this time, I cannot add the Klipsch RS-3IIs for rears (they are too wide at 17" for my setup). This being the case, it is possible for me to move my current floorstanding speakers back to be used as rears. Is this feasible? Would using my current floorstanding speakers as surrounds be a better alternative than continuing to use my current tiny Sony ones? Additionally, I do plan to move my existing center channel speaker to the back of the room, for a 6.1 setup. Also, both speakers would have to be raised about 2-3 feet off of the ground, so they fire over my couch, and would be on the left and right sides of my couch, firing toward the listening position. This being the case, I can't really test them until I buy or construct some stands. Should I go out and grab/build some stands and try this, or just stick with my current surrounds? Thanks for the help!
