I have a home-built 18" cab that's served me faithfully for 20 + years. I recently picked up a GK MB200 to gig the smaller places, and when it get the amp close to 3/4 max on the volume, I get a horrific buzz/vibration from the speaker on certain mid range notes, mainly the A string. I thought cracked cone, but that's not it. Tightend up the speaker, but still get it.
I can't remember what the cab can handle, is the MB200 too hot for it, or maybe something I can glue to get the vibration out? Maybe something loose in a baffle?
