I would like very much to use the RC 64 with a RB 81. I have to use a rb 81 because I have a shelf where the plasma tv is. (Both the rb 81 and rc 64 fit perfectly into the shelf) I cannot use any floorstanding speakers due to acceptance by wife problems. The room is 7meters by 5.5meters. I feel the rc 62 would be too small. Would it be too much of a mis match? would the sound be too different between the main and the center speakers? RC 62 just looks tooo small! HELP!
