Funny this thread came up as I'm using pink noise just starting today to break in my new Seas drivers. There is a harsh breakup mode at 5kHz as shown by a steep dip in frequency response as seen on my Behringer DEQ2496 when I run pink noise through the speakers. Apparently the driver stops outputting in the 5kHz area. Love the Behringer as it shows stuff nothing else does. Doesn't show up with Stereophile's 1/3 octave frequency tones. Did a little with their chromatic scales but they move so fast cannot measure to adjust the eq. Also they don't go over something like 4kHz.
I have a definitive test for improvement....my ears will stop hurting. Doubt the pink noise will do this but will give it 4 days at 8-10 hours per day. My previous experience is that nothing will fix this and I end up coating the driver with C37 violin varnish. Wish me luck as it is non-reversible and Seas Excel ain't cheap. Living on the wild side =:o)
