Wow, got lucky. Drivers must have had good mechanical stops.
Drivers survived
My midrange and woofer drivers survived a serious electronic crossover failure that put over 300 and 500 watts RMS into each of them for about 5 seconds. All LED’s on the front panel of 2 of the 3 amplifiers lit up like a Christmas tree, including the +3db indicators. I thought for sure the midranges were history and maybe the woofers too. I do not have anything but copper wire between all driver voice coils amplifier outputs. Thanks goodness the tweeters did not see that tone at all. I had not thought about a crossover failure…
