I have the Klipsch RF-63 floorstanders. The matching center channel recommended by klipsch is the rc-64. But I have found a good deal on the rc-62. Would it be a bad idea to pair the rc-62 with the rf-63? Also the same applies for the rears. The recommended pair is the rs-62s but I have found the rs-52s for a really good price. What do yall think?
