Marshall 4x12 Guitar Cab making horrible sound

[agreatheight]

I haven't noticed this happening before...

Today when I plugged into my Marshall 4x12 guitar cab is made a horrible buzzing mweeerrrrp sound when I played. It sounded like the entire cab was vibrating. Very bad. It only happened when I played with a bassier distortion and was much worse on certain notes / chords, notably A#. I wasn't pushing the amp too hard (reasonable volume) and was running the correct ohms from amp to cab. A friend said that the cab might be 'tuned' to a certain frequency and that the cab was sympathetically vibrating when I played near or at that frequency, but I don't remember that happening before plus that seems a bit crazy to me.

Any ideas? Anyone know where else on the net to ask?

Thanks in advance!

TB has it's own amps forum right under the Basses forum.

As this question is about a guitar cab I though misc might be best. Hmmm... gonna kill this and resubmit in Amps...

I don't.

Check to see that all the speakers are properly affixed- ie: all four nuts are securely tightened on each speaker.
