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.

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.

Hello,
Kenjit, Can you explain why a mechanical object breaking in cannot be measured. A woofer gets better excursion over time. It levels out at a point, but definitely changes. Since the driver is just a motor moving air to make sound the more efficient the motor becomes the more nuanced sound it can create. This is most notable at low volumes after the break in period. The same thing happens to a car engine. It actually gets better gas mileage after 5000 miles than it did at mile 100. If I am wrong please explain your comment so I can be educated.
