UNPLANNED DOWNTIME: 12th Oct 23:45
I bought a second hand Ashdown RM210T cabinet recently off Ebay.
I have found it has an annoying buzz when playing F, F#, G in any octave. I have opened it up and secured the cables with zip ties and padding so that they can't "buzz" against anything - no difference
I have touched and pressed everything inside to see if there is something loose. All seems fine.
The cabinet doesn't seem to have any splits or cracks
I can push and hold and squeeze the drivers and body of the speakers and it makes no difference
Horn on/off makes no difference.
Unscrewing and pulling out the connections plate makes no diference.
All feet and corner protectors are firmly done up.
I even trimmed off some excess material that might have been flapping about around the handle and connector cut outs - no difference.
I thought about disconnecting the speakers one at a time, but wasn't sure if I might damage my amp when testing it, so didn't...
Anyone any ideas?

It should be safe to disconnect each speaker as well if you're not sure - just be careful with the volume. I'm almost certain they'll be wired in parallel so the cab impedance will rise and restrict the power of the amp anyway.

Well done on trying it in another room to work out that the cab is not faulty.

Getting the four spikes of a hi-fi speaker to bear the speakers weight evenly is a bit of a challenge. The best way is to set the cabinet using three spikes and lock the spikes, then lower the fourth spike {by hand] until it contacts the floor - then lock it. This might solve it first time or more likely after five or six goes as the speaker must be vertical and no rocking on the spikes. I am only saying this as it seems the bass bin problem alluded to above has parallels with hi-fi speaker placement.
