Do speakers take time to warm up?

For example, if my stereo is on and has been on for weeks, and then I connect speakers that have been sitting idle for a few weeks, do the speakers sound better after an hour of being played?  Whats going on?  Is it the caps in the crossover, the drivers, the ferrofluid in the tweeters?  All of the above?

It is possible that I put up more audio systems and conduct careful listening to them in one year in my home than you may have built in your lifetime. So, your mockery means little to me. If you are not going to discuss this in a mature way, I’m done talking with you.
ie I am right and know more because I have far more experience than you. Sorry, not a very convincing argument. You know absolutely nothing about me that makes you qualified to make such an arrogant and sweeping statement.

If you really think that a voice coil resistance change in excess of 10% can have no audible effect I suggest you go back to EE101.

 Measurements do not support contention of break in or warm up being audible

 Seems to be more measured difference between cables than “warmed up” speakers. 


Now, anyone who disagrees, how about you show me/us the measurements that demonstrate the purported audible change that occurs when speakers "warm up"? Surely this has been proven time and again, right? We should have hundreds of sets of such measurements, right? This should be well documented, right? I suspect not, because it would have been very easy for you to provide such contrasting measurements were they available. 

Maybe I am wrong. Maybe there are lots of sets of measurements out there proving that speakers change sound significantly during break in and warm up. Show them to me. 


I do not need to provide measurements in order to show that human hearing is not absolutely stable. However, someone who wishes to show that electronics and speakers undergo audible changes due to warm up need to show measurements, imo, or there is no compelling reason to believe it.   :)

And guess what! There was excellent scientific evidence presented for precisely the opposite case on the exact same page. And maybe I did notice just a teensy weensy bit of an agenda running through the forum, just perhaps of course........it was probably just me..........

And Douglas, please stick your slide rule (sorry Millennials) back in your pocket. We really don’t need another one of THOSE dead end threads.

My take is: there’s an awful lot of experienced listeners out there with really good hearing who regularly experience this phenomenon day in day out, and accept it as a fact of life.

What are its primary causes? I know you have your answers, but I would like to hear some others’ opinions.
