I second the RF-7II/RC-64II combo but you could try with your RC-64 v1 to see how well it will timbre match. IMO, no need to swap out your RS-52 surrounds. Definitely get a better sub than your current RW-12D.

Klipsch Speakers, Where Should I Look For The Best PRices
What is the best place to buy new or B stock Klipsch? I have a 5.1 setup now anchored by RF-82’s, RC-64, RS 52s and an RW12d. My thoughts are to move to 7.1 and maybe Atmos and moving the 82s to the rear and adding another amp to my Emotiva XPA-5. My Marantz pre-amp can handle up to 11.1. Speakers under consideration are Forte’s, Cornwall’s and RF-7s for the mains and Klipsch’s current 15 inch reference sub. The second amp would probably be a smaller Emotiva or an Outlaw. My music tastes are AC/DC and the like. I’m hard of hearing so efficient speakers are a must. What do you think?
