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.

Thanks but yes it has 5 total fuses and all are fine. Nothing stands out as bad upon visual inspection. It knocked loudly then right channel was gone. Cheers
For record Aragon was obviously older amp, my other concern is if amp may be repaired and potential cost. I know its a stab in dark. Thanks
Hmmm, great info and food for thought. THANKS!
I am going to send the planar line array to VMPS for inspection, I talked to Brian yesterday. My largest concern is it always seams to be right channel thus a inspection of the series/parellel or reverse (I get them confused) is a culprit. 6drivers per side are wired in pairs then those three sets are joined. After that is looked into I will look at my best bet for the amp repair or to replace. Again thanks
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.
