Center channel to complement Klipsch Fortes

Let me start by saying first that I am brand new to this site and second that I am probably not a true audiophile; I love nice equipment, and about 20 years ago invested in an above-average system, but I am not well versed in all the technical aspects and so forth.

That said, I am looking to convert from my current set up (Klipsch Fortes and a Nakamichi SR-3A) to home theater and am wondering if there is any good center channel that mates up with the Fortes.

I'm told that it's important a center channel have the exact same tweeter as the fronts but am guessing that Klipsch wasn't making center channels back in 1985 when the I believe the Fortes were produced.

Am I better off selling the Fortes and starting anew? If so, what would you all suggest as a close match to that wonderful Klipsch sound? I'm told that Klipsch themselves has drifted into the the lower-end market these days. Is that true?

Thanks in advance for your help.
