I have 2 Klipsch RB-51s for my fronts and just got a RC-62 for a center to replace my old Synergy set up. Will the larger RC-62 be mismatched with the smaller woofer RB-51s? The rest of the set up is SS-.5s for the rears and a KSW-12 for the sub powered by a Denon 1910 when it finally gets sent to me. I plan on upgrading the rears when I have more cash. This will be for 90% movies, 10% music. Thanks!
