Feeback breaking something depends on the proximity, duration, frequency and
power. Normal
feedback I have seen happen so loudly but never blow a thing...and other times I have seen stupid clueless musicians too busy tryin to look like a rockstar knock a
mic stand directly so it falls right into the monitor--and the
feedback is intense but very short lived--about 1 second before the drivers blow. Then they scratch their head wondering what did they do wrong and why its their fault the band has no more
stage monitors.... "How could I be responsible--I looked SOO COOOL MAAAAN....whadda ya mean the drivers cost $200 each and there are 6 of them...I don't make that much money in a YEAR maaan....".
here's your sign....
