Your description is accurate. I had my local dealer loan me both RF-83 and RF-63 w/ RC-64 center . He was really great about it, as he had to deliver to my second floor home theater, which I have nearly completed. I have all weekend to tweak and listen to both. So far I have only listened to the 83's. I am set up the speaker size on the preamp and need your opinion to set speakers at "Large" or " Small". I have two subs that seem to work so far, but could go full range on the L & R.
After setting up and extensive listening to both sets of speakers I will give you my review and decision on which I choose. I listen to loud rock video, but also detailed movies, so the RF-63 are hopefully up to both.
At any rate the dealer was so great and matched my internet pricing. He will pick up whichever I decide I don't want to keep.
