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.

Sounds like a protection relay. It may be that a device overheated and failed- thus the protection relay kicked in to prevent the amp from destroying the speaker.

Either way it sounds like service is indicated. I would weigh the cost of repair against how the amplifier served your needs; if a replacement amp is costing over just a few hundred dollars then its likely the amp is very well worth repair, assuming service info is available.

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.

Mcintech makes an excellent point! Check your fuses with a DVM.

How does the amp behave if there is no speaker load?
