Hi all, just replaced my SuperSat 50c with a SuperCenter XL, all existing equipment stayed the same. I ran the audyssey pro calibration . I am noticing a very apparent buzzing sound come from the ribbon tweeter during higher frequency passages. Any ideas?

Have you tried swapping out the Supercenter with another speaker? If the buzz goes away there's a problem with the Supercenter...may need to take it back to your dealer.

That's a good suggestion, hook it up to the left or right channel and play some music, any buzzes should still be there and even more obvious. If the speaker is OK, you might then want to try the system without the room EQ calibration and just manual setup.

If the buzz persists, see your dealer. Not likely the tweeter, buzzing is almost always the mid-bass driver (exposed gap can get debris in it from the shipping process).
