Well, you got my opinion on the fronts.
As for the center, I dunno. Generally they SHOULD match the fronts but, since thev have been out of production for about 15 years, you have to see how well your new center plays wit them. It's good brand, though.
Rears, for HT are less critical than the front three since they are generally called upon for ambiance and the occasional gunshot or laser blast.
As for subs? Hsu or SVS.
