Is this a logical break in technique?

Just listen to your speakers and enjoy them. They will break in gradually over time and you'll probably not notice much, since you'll get use to them. Just avoid really loud volume at first; and just use lower volume when you leave the system on while not listening.

Not sure "pink noise" would do the trick. Woofer/Mid drivers will break in some my moving. Most tend to be a little on the stiff side when new. A constant tone or noise may not do this.

Rock or Jazz probably does not really matter either. I would not break in speakers at high volume anyway. At lower volume they are likely to have about the same effect.

Play some jazz/rock... LOL !!

Now, I'm not joking - and I hate to reveal my best-kept secrets - but what I use for break-in, because it contains virtually all the elements from jazz, rock, and classical with strong dynamics is '70's "orchestral" disco such as the Salsoul Orchestra.

It contains the full range of strings, strong bass, solo sax, synthesizer and guitar, and voice.

Though some people might prefer listening to pink noise instead :)

wait a minute, wait a minute!
I know that Arthur is doing his Ph.D that's why he canuse such big terms like "triboelectric noise" but it happens to be in Class-D amps.....:-)

the speaker driver consists of a fixed magnet. the music signal current carrying conductor immersed in this fixed magnetic field causes the driver to flex back & forth. Take away the music signal & the driver stops moving. Assuming that the speaker internal wiring/conductor is sized correctly to carry the expected current, the conductor should *not* be stressed => the domain spins of the conductor material should not be distorted. IOW, the domain spins should return to their quiescent state. I.E. the conductor/speaker internal cabling should be memory-less.
Also, if you look at the *average* value of a music signal over a long period of time (the originator of the post suggested playing Jazz/Rock for 1 year straight), it is practically zero. IOW, it should leave the conductor/speaker internal cabling without any memory.
Anyway, just my thoughts FWIW.

Perhaps the domain spins will return to their quiescent state, and perhaps not. It would require a careful assessment of the relationship between the fixed magnetic field and the signal-carrying conductor to see if this is the case. I would suspect that some work on this has been done by speaker manufacturers to determine the shielding necessary to prevent any sort of interaction. Also, magnetic materials are tricky since they have residual flux whose value changes depending on the last circuit operating point - even if it is simply induced. This problem becomes very significant in large transformers where you can have a huge power surge when you bring one online if the residual flux level is high. Whether a fixed speaker magnet can have this problem enough to affect the sound is another matter...I suspect the woofer surround has a much larger impact than that at any rate.

Either way though, there is more to it than the speaker and there is no clear answer to the question! Fun to think about though.

bombaywalla & aball.

damm,did your heads swell up the size of watermellons to learn all this stuff or what,jesus i read both posts 10 times & i still dont understand a lick of it & i dont even smoke pot.

im not knockin what either of you guys said im just sayin its way over my fat head.

mike.
