I have SB-3's as fronts and SB-1's for the rears and I have a chance to buy an RC-3 or RC-3II center channel. Do you think they will blend well together? Right now I'm using a JBL Northridge center and it's very flat (Tin canny). I know I would be mixing two differant families (Synergy and Reference) but I plan on over time upgrading to the reference series for all of my speakers. What do you think?
