TBC: There are a number of times when speaker makers have measured the break in of a woofer.
The annoyance for us is that driver manufacturers (not speaker makers) specify the drivers after being broken in, but we get them without, so when we measure them they don’t necessarily match up for a while.
YMMV, different drivers, suspensions, etc. will behave differently. Usually this has to do with the resonant frequency dropping after use. That’s a key component of cabinet design, which is why it can be really annoying.
