Why is the audio system have a high frequency range?
Some amplifiers have high quality audio frequency range up to 40 KHz say which is two times that nobody could hear, as you can handle perhaps 20 kHz at most. But I seem to recall that there is a real reason for building amplifier with these specifications. Something to do with harmonics, possibly. Someone has a good explanation?
Any team good audio quality is designed to operate at very low frequency range from DC to audible (above 20 kHz). The RF spectrum is not efficiently radiating to over 100 kHz. If an amplifier or transducer has a range from DC to, say about 40 kHz, has a wide audience through the plane "portion" of the spectrum and a wider overall dynamic.
