How many hours to break in AP codex speakers?

It will vary wildly from speaker to speaker.  My experience on my speakers has been for the first 5-10 hours after install dynamic changes in volume within a piece of music are incoherent.  Transitions from quiet to loud are poor.  This has been the case with both SEAS and Eton drivers.  This was called out to me by the engineers at Eton as something to expect.  

Over the next 10-50 hours I have not heard a significant change in the character of the sound but detail improves and the soundstage comes together more easily.  The louder they are played, the more quickly they break-in.  


Not that I’m a fan of Klipsch, but- they may have a valid opinion on the subject, given they’ve been in the game for a while: https://www.klipsch.com/blog/how-to-break-in-a-speaker#targetText=After%20about%20100%20hours%20of,while%20others%20can%20change%20dramatically.                                                                                                                                                                                 Then there’s: https://www.cambridgeaudio.com/usa/en/blog/how-run-speakers                                                                                                                                                                                                                                                 Oh, and these guys MIGHT know a thing or two, as well: https://www.eminence.com/speaker-break-in/                                                                                                                                                                                                                          Opinions on hours vary widely, as do the mechanics/materials of various drivers.

I bet you have never purchased a new subwoofer !  

@jljYI have ha this happen too. a set of PSB towers became overly bass dominant after 2-1/2 years.  Sold 'em.  

A recent set of Spendor towers took 250 hrs to sound really good and they were still changing after that.  

A new set of Harbeths are sounding great at 70 Hours   (all above hours carefully logged). Â
