Цитата про знаменитый пик гитарного динамика на частоте 3.9 кГц или около того:Those response peaks often live in the most *!@#%^& annoying parts of the audible spectrum. Seriously. Infants cry in that range because it really, really, REALLY gets the attention of everyone around them. It’s impossible to ignore. It sounds like someone is running a drill inside your ear canal.
…and there are guitar-cab drivers where the “baby-cry peak” is 8 dB higher than everything else in the spectrum. That’s a bit more than six times as intense.
So, you’ve got yourself a device that’s very good at making irritating frequencies, good at focusing those frequencies into a small dispersion area, and (usually) lacks the kind of surgical tone control necessary to fix the screech.
