I have 2 pairs of Titans, 2 Atoms, and a CC-170. I've noticed, while watching some movies, most notably the latest Cheaper by the Dozen, that my center channel has a slight static or buzzy sound to it during primarily dialogue. It's pretty slight, and it only seems to be while people use sharp letters like S or T. It freaked me out a little, so last night I switched my center channel wires over to one of my Titans. I played back that same part at that same moment and I noticed the static again. I did, however, think the Titan sounded significantly better than the CC-170 running in the center. The highs seemed crisper and more pronounced, and the lows deeper. Any ideas what the scoop is here folks? I know the Titan is using a 6.5 driver and the CC-170 uses twin 5.5 drivers. But the tweeter should be the same. The highs are still coming out of the center, and I could detect things like keys rattling, and such, but it seems like the center almost isn't timbre matched to the rest of my system. Is it possible I could have blown my tweeter? But if that's the case, then why would I notice that static through the Titan as well? On the other hand, I suppose it could be my receiver. I'm running a Kenwood VR-507 that's "rated" at 100W per channel into 5 channels. And I've never turned it up above about 3/4 of the way up, but it feels like I have to turn it up to about -30 or so (on a scale from -100 to 0) for it to get to the volume I'm wanting. I'm assuming if I take it to the dealer, and he hooks it up to one of their high-end Integra receivers, he'll be able to tell me if there is something wrong with the speaker. And I'd also assume, if indeed something is wrong, that Paradigm would replace/repair the center since I've only had my speakers for about 3 months. Maybe the CC-270 would be a better match since it uses the larger drivers and would better match the fullness of the Titans.
