I was originally planning to but PSB all around, then I listened to the RF-3's and thought that it would be worth shelling out the extra cash. I know it's better if I had the same type of speakers, so how bad would it get if I mix and match?
I guess if it makes you happy that is what really counts. The RF-3's are really efficient and will probably have a tone that is just not right with the PSB centre. The most important speakers to match in a HT system are the front three. I would recomend getting the RC-3 to have a seamless front sound stage.
If you are buying all three speakers anyway then I would suggest buying from the same manufacturer...ideally the same speaker for your front stage. In a pinch a mismatch can still deliver decent results, but not when compared to a well matched setup. I had been using an Infinity Kappa center with my Signet SL260s for the longest time. It always bothered me and when I upgraded to a matching Signet speaker, the differences were night and day. - Jeff
