Re: Audio Question
You'll find that music can/will contain frequency content below 35Hz and well above 30KHz. The thing is you won't hear the low frequencies, you feel them, and the high frequencies tend to add sparkle/glitter to the high end.
Most decent audio amplifiers will replicate frequencies from 1Hz to well above 40Khz.
Read the specs carefully. Just cause an audio item says 20Hz to 20KHz @ -3dB doesn't mean that it wont reproduce frequencies above or below this figure. It will but usually falls off at so many dB's per octave.
Frequencies above and below our audio hearing range are very important, if mixed/mastered correctly.
