I am still not getting your basis for this statement. Keep in mind that the frequency spectra is flat for both ideal white noise and an ideal impulse (delta function). The entire difference between these two signals is contained in the relative phase (linear for the impulse, random for the white noise). If you were only to look at the amplitude of the frequency response you would not be able to distinguish the two. I don't doubt that drivers designed to give flat frequency response are most likely also designed to provide accurate phase. However, I see no reason to believe that flat frequency response necessarily guarantees accurate phase response, and therefore good transient response.
