Frequency and phase response are just linear characterisations, they don't model any non-linear effects.
That being said, speakers and headphones all have a sound (unlike any properly designed amplifier); there is hardly any right or wrong there, and while the best approximation of a flat response might seem technically most correct, people will probably prefer different sounds.
- codedokode 9y agoNon-linear effects can be seen when measuring THD. Any non-linearity will distort the sound and create additional frequencies in the output.
- dom0 9y agoThat's not correct. THD measures some non-linearities and is unable to detect others (e.g. IMD).
