Thank you for the quick response I know that RB is normally set to operate at the rear and the RF series rather to the front. But as my budget is limited, I was wondering if RB 61 II or RB 81 II in a small room of 200 ft² could suffice in the front. This is not the entry level of this line; however the RF 42 II or RF 52 II is the entry level of the RF series. In your opinion, what are the major differences between there tower and there bookshelf especially for a use audiophile. I have a room to keep them off the wall; the position will not be a problem. I cannot find a dealer Klipsh with the new line RB II or RF II in Montreal area.
