How could someone damage the speakers?
I have a very unstable amp and I'm worried to have damaged the speakers. Yesterday I heard an incredibly powerful 'BVUUUF'.
Could I have damaged the speakers? I heard it two times (the amplifier sounded for 10 seconds then 'BVUUUF' until I turned off, then I have repeated the sequence and same problem).
Do you think that I will have to change the speakers (Tannoy F2) with the amps? Or are they strong enough to sustain those 'cracks'? :(
That depends on what's wrong with the amp.
Get that amp fixed. It's broken.
The speakers most likely survived for now but I wouldn't push my luck and keep playing it.
But, you really won't know for sure about the speakers health until you use them with a properly functioning amp.
