In Reply to: Call BS all you want, most [honest] speaker designers will tell you the same thing posted by John Ashman on November 9, 2006 at 12:37:08:
Yes, most of it occurs in the first 24-48 hours of playing time, but there can be incremental improvements for days after first firing up a "green" speaker system.For simple 'ballpark' T-S parameter lab measurements, I can break-in a woofer in a few hours, but for a system, it takes longer than that for all the sonic details we can hear to settle-in.
I never voice a speaker with green drivers, the end result will be too different after the system has been playing for while.
All of this relates to home hi-fi speakers, things are somewhat different for Pro-sound speakers/systems, nearly continuous high power exposure can accelerate the process, and there is inherently less nuance to be heard in the first place, so break-in is not as long, or as critical.
