So there's a good possibility that I may be getting a new LCR that're rated as 4ohm speakers. My current LR are 6ohm which will be moved to surround duty if all works out. I also have a pair of 8ohm speakers as the 6&7th channels. I have a Sony 4400ES that has a 4ohm or a 8ohm setting. Right now I'm using the 8ohm setting for the 6&8ohm speakers with no problems. How would the 4ohm LCR impact my setup? Would I just change to the 4ohm setting on the sony and all should be well? I want to eventually get a separate amp which should void any of these problems I think, but for now would just be running off the receiver. Am I missing anything?
