One only has to visualize what is actually going on when an instrument is playing, in this case a simple 6 string guitar to realize that a lowly driver is asked to reproduce all the complexity that is going on at once. The pure tones along with all the harmonics of each string captured by a moving diaphragm of a mike and fed through a whole chain of electronics down to the lowly driver/drivers which are supposed to reproduce them all at once faithfully. It is rather amazing that such a complex waveform fed through the whole chain of audio playback comes pretty darn close to tricking our ears into a semi-believable facsimile of recorded music.
Watch this video and think about it.
