Hello,
 +
the limits of 20 Hz and 20 kHz are largely meaningless and physically unjustifiable. Roughly speaking, they result from the audibility of steady signals - which hardly ever occur, especially not in music. Therefore, they do not take into account the audible rise times, although this is where the information lies. A limit of 100 - 150 kHz would be more realistic.

Hello,

what you wrote is true.

But it is also true that 20 ... 20,000 Hz roughly describe human hearing and thus also represent (an easily achievable today) measure for hifi technology. And also that the straightness of a frequency response reveals something about the capabilities of a component and the characteristics of the design. Of course you need some knowledge about the dB scale (logarithmic !) and how much of it is audible.

With loudspeakers, room acoustics and placement of course play a role, but this is not the case with electronics. Obviously it is often helpful in hifi technology to show more than 20,000 Hz, no matter if tweeter, amplifier, pickup systems.

Hope there's something more to come - had promised myself more under your heading . . .

Many greetings Analoghatwas
