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

@mijostyn- You began your post, mentioning pain and ended with, "fiction". Those two words bracket, what they so aptly describe.

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. 😬
