Thanks for the replies. Last night I hooked up one of the RF-15's as the center. Sounded really nice. Voices were clearer than I have ever heard them. Looks kind of funny with 3 towers across the front of the room however. And I have one RF-15 left over. I do appreciate your time and consideration

I have had my Klipsch home theater for about 10 years now. Klipsch 12 sub died after 2 year of use so now I have a Polk in its place. I just replaced my older 5.5 inch fronts(RF-15) with 2 RP 8000 F's. Sound great. Now I am think about by center. Not sure of the model but it has 2 4" drivers and, of course, the horn. I am wondering if the 504c or 404c would be a good replacement for the center and why. Which one? By the way I have smaller 3 inch sides and bookshelf 6 inch Klipsch at the rear. Thinking about moving the old floor standers to the rear. I also have the 500SA's for upfiring atmos. Stupid me however, forgot I had an acoustic suspended ceiling. All driven by a Marantz SR 6010 with separate amp for the atmos speakers. So back to the question............504c's or 404c's. I am also open to other Klipsch suggestions that may match more appropriately. Could I use one of my old RF-15's as a center speaker? Thanks Rick
