Unfortunately my hearing was unprotected in 100+ db music for hours on end, for years and years and I am paying the price now. These systems could literally knock the wind out of you with a bass note (dozens of JBL 12-15" drivers driven by gobs of current). All us guys from the 80's crew are dealing with hearing problems. That's why I like the 801's with diesel powered amps, it's the only thing I can hear.
