A speaker physics question.

[Old Guy]

Ok just to be on the same wavelength, by flat response do you mean that all the frequency's are coming out at the same volume or decibel? I understand the phase part...I think.

One pure sound a fraction of a second after the next



Sum of two waves slightly out of phase

Essentially with out of phase issues some frequencies will add, others will cancel. The result is exaggerated peaks and dips. This is why the enclosure can not exhibit smooth response over a wide band.
