Once again, you prove that you have almost no idea how and why speaker companies design, build and test speakers.
When frequency response is measured, white noise is used (all frequencies at equal amplitude).
Please see the 1998 book Testing Loudspeakers by Joseph D'Appolito:

I refer you specifically to section 4.5.1 which explains why pink noise is used. I further refer you to the rest of the chapter which explains why this is best suited for equalization of a system in place, nowhere does he rely on either type of noise for speaker analysis or design.
Further, with the advent of high power general purpose CPUs even using pink noise for a system in place is seriously outclassed by modern test instruments and methods and neither Stereophile nor Soundstage use either type of noise when measuring speakers.
If you don't believe in science and engineering please ignore this entire post.
Thank you,
