I think my speakers are killing my amps.


I have VMPS FF3 SRE bi-amped w outboard crossover, I have upgraded from the original single panel to the multi planar driver option.
I ran 300w Classe amp on panels but at around 95db it would go into protection. I changed to Aragon 4004 MKII 2 yrs ago that gave 400w and thought I was good till yesterday but while playing pretty loud maybe 100db the amp started making these loud clicking sounds the one channel was just dead. Now I wonder if a mistake was made in planar drivers wiring or in updated crossover. Its possible amp finally bit it after some years of great service but its always the same speaker and it has sent multiple amps into fits. I think maybe its down to 1ohm brutal swing or something but am not smart in that area of electronics. Any ideas would be great, thanks. BTW Classe is in service now but not at loud levels.

The VMPS is not particularly capacitive. Ribbons in general tend to have a fairly resistive quality so other than impedance they tend to be easy loads.
It possible a capacitor may have arced. I have seen situations where the speaker was damaged by high frequency oscillation before the amp failed. Given its age, it sounds like the amp needs some tlc.
Did you measure the fuses with an ohmmeter or did you just visually inspect them? Had several fuses over the years that appeared to have intact elements but were wide open electrically.
Will do, thanks for info. Though the click clack sound the amp made (not through speakers it was mechanical) tells me its more than fuse.
