Other manufacturers have similar "pre-conditioning" stated in their customer approval specifications, including for hf drivers. I had occasion to review many such sheets as I commissioned and co-designed a number of drivers.
Does this break-in (would not call it burn-in which is a different thing in my mind) that minutes, hours, days, weeks, months, years or decades ?
What would be the average time before one can use it. (The linked data sheet states 2 hours and 10 hours 'rest')
That would be a far cry from the years some make it out to be.
Comparing 2 speakers that were both manufactured around the same time and checked for performance, one was used 'normally' and the other was stored in ideal condition and then later on (say a year or so) where measured again would reveal difference due to 'usage'
A question would be would headphone drivers be affected in a similar way ? Very different construction, materials, scale, mass, 'beating' it has gotten.
I have measured new headphones, for instance, right out of the box (without listening to it first), played with them, measured them again and even measured them years later again (same fixture, same everything) and found no real differences that could not be explained by differences in positioning, pad wear.
Speakers... I am sure there is break-in. But how long does it take is the biggest question. I mean, how can one tune a bass port if the speaker resonance point keeps on changing?
Other than anecdotal (mine is obvious also anecdotal) do you have any official documentation you can share, say a now obsolete product, which would not be under an NDA ?
