Can speakers sound worse during break-in period?

I purchased a NOS pr of speakers ( I’m not disclosing their name. Not interested in hearing from their haters) and was really liking them before I started to seriously break them in. It seems like after 24 hours they seem to have changed and sound worse, or not as good as they did. Are they just going through changes with some drivers opening up faster than the others? I know there are many components involved in this process and some might be a head of the others. I’m assuming that’s the case and when everything comes together they will sing.

Whether it can be measured is not the issue. The question is how significant is it if its audible? There are many more problems that can ruin the sound of a speaker and people that focus on things like cables and break in of drivers dont realize that. How about custom tuning the speakers with a bit of equalization? How about retuning the crossover? I tend to agree with what Harbeth wrote.

If you dont like what youre hearing its very unlikely that break in has anything to do with it. Has the OP bothered to retune the crossover to see how that sounds? If not, why not?

To have a guy that is clueless and argues almost every point under gods creation is one thing,  but to have a guy chime in that calls himself a manufacture that apparently has never taken the time to measure drivers at several points of break in is beyond my comprehension.  FS, QMS, QTS and even LE and RE all change as the motor and suspension break in.  It is threads like this that makes me back off of posting.

I am most fond of posters who argue one thing one day, and then within the same thread argue exactly the opposite. That kind of gymnastics will always be pretty amazing to watch.

Hello, 
Maybe we are coming at this in different directions. I still believe in what I said, but if I am understanding this is that the speakers should always sound good and get better. Just like my car analogy. If it sounds bad then something else is wrong. The only thing I can think is if you break in with a limited amount of frequencies you may run into some issues. If you play 1khz for a hundred hours then the woofer did not move due to the crossovers.  If break in on a speaker is not real then why do most manufacturers recommend this and tell the dealers to do this? Is there a representative from a speaker manufacturer that can weigh in on this? Maybe the OPs crossover is messed or he had some interference from other things.
