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.

I understand Zu "burn" their drivers in for 400 hours prior to installing them in the cabinet and I believe they still exhibit minor tonal changes after using them in the home.
Whether that is due to the amp or further "burning in" is beyond me.
