Is this a logical break in technique?

Background of theory; take 3 people (just to explain my point, if this is even a point) each listen to different types of music. One rock, one jazz and one classical-keep it simple, if each one of these people only listen to one particular type of music for the entire break in period, do the speakers remember the focal points in the freq range of that type of music. Because jazz can be light, rock can be heavy and classical can be both as can all the genres but one genres compared to the other are recorded with different end results in mind.

Basically would it be better to break in a pair of speakers with pink noise and run the tones at different db’s just to expose the speaker to different signals basically training the speaker to produce anything and everything.

Example:

I listen to Jazz for 1 year straight on the same system as my friend. at moderate levels

My friend listen to rock for 1 year straight on the same system.

Say we swap system but not genres would there be a sound difference? If yes then this theory might have something to it. If not I need to lay off the weed.

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.

I have wondered exactly the same thing. From the stand point of triboelectric noise theory, the answer to the question is "yes," the systems would break-in differently and sound different since the electromagnetic fields of the signals will be changing the domain spins of the material in ways according to the music's harmonic structure.

However, the question is, more precisely, how much deviation from the noise average is required to cover the possible domain wall spins and/or scramble them enough to make the signature of the break-in independant of the music being played. It is a very interesting subject and I am starting to conduct my own research into it.

Pink noise is a good idea but there isn't anything that will prevent the system from de-breaking-in when you aren't listening to pink noise for extended periods (which I would say is most of the time!). This is assuming today's research is accurate which in and of itself isn't clear since our measurement capabilities aren't that good.

I can blab forever about this topic so if you are interested in more details, let me know. Anyway, sounds like the weed is making you think in the right direction. keep it up! ;) Arthur
