Hi,
There is a distinct rattle from one of the Celetion G12T-75 speakers in my jcm900 2x12 combo. I have taken the speakers out of the enclosure to ensure it wasnt something in the cabinet rattling. I am certain the rattle is coming from just one of the speakers. It only occurs at certain frequencies. I have measured its DC resistance and it seems normal for a 16 ohm speaker. I can't see any cuts or holes in the speaker cone. It sounds very much like a rattlesnake!

What the hell could the problem be? It seems more pronounced when playing clean, but I assume that is because it doesnt blend in with any distortion.

Any help is greatly appreciated!
