Thanks Frzninvt. I do already have the timbre matched KLF-C7 though. My issue is that the KLF-C7 is always too tall fo fit where I need it to. I need to downsize the center speaker to fit with my tv stand and furniture. That is the reason I have been looking at the RC-62/RC-64. I love the way the Legends towers sound, I just need a center speaker with a shorter cabinet that still sounds good with the KLF-20's.
As I mentioned, I may end up changing over to the RF-83 towers in the future to replace the KLF-20 towers so a future timbre match may be possible. I am not sure how different the RF is over the KLF being one is a 2 way speaker and the other is a 3 way. I do not want to give up the sound from the KLF towers, though, which I enjoy mostly listening to music.
