Speaker Break In...? Or listener “Break In”?

this should not be a question for anyone who has ever purchased new speakers and paid attention to them.  

Magnepan recognizes, that it’s speakers have a, "break-in period’(second page of their 20.7 manual, last paragraph): https://www.magnepan.com/pdfs/manual/MG-20.7.pdf One would think, a major manufacturer like Classe’ would know better: https://manualsdump.com/en/manuals/classe_audio-ca-m400/10994/8 Or Wells(under, Proper Care): http://www.wellsaudio.com/akasha-manual Hell, even Bass players are aware of the reality(under, "WE USED TO HAVE SOME SOUND FILES (HERE)" : https://barefacedbass.com/technical-information.htm Of course; your ears and opinions may vary, but- who cares?   If ignorance is bliss; some here must be experiencing Nirvana.

Take a poll of manufacturers. Yeah, like that’s a way to get to the bottom of this. 😬 

TBC: There are a number of times when speaker makers have measured the break in of a woofer.

The annoyance for us is that driver manufacturers (not speaker makers) specify the drivers after being broken in, but we get them without, so when we measure them they don’t necessarily match up for a while.

YMMV, different drivers, suspensions, etc. will behave differently. Usually this has to do with the resonant frequency dropping after use. That’s a key component of cabinet design, which is why it can be really annoying.

Best,
