90kHz??? Sta je to muzika za sismise? Cuje covjek uopce preko 30kHz?

navodno ne cuje preko 20kHz a kako matori ili prepanjuje SPL tako cuje sve nize

I cemu onda taj raspon do 90kHz???

da bi se folirali, a mozda i zbog kucnih ljubimaca

ma to je neka stamparska greska, otkad ringradiatori mogu da sviraju tako visoko?!
