I'll start with woofers, it is mechanical and easy to understand.A woofer does not burn in within the first few minutes of play but can take 50 to 100 hours. The measured T/S parameters will shift. Some shift in one direction and some in another. Optimal box volume and or tuning frequency changes little as the changes can cancel one another out. Where you might see some measured difference in frequency response is in a really low region that is hard to accurately measure in the first place. How it sounds does change.
Capacitors can change quite a bit as well during burn in, but the measured value will remain the same.
Most anyone with good gear and an ear to hear with always report a smoothing out of the top end after many hours of burn in. This is due to the caps burning in.
I have the luxury of often having identical pairs of speakers for audition. If one pair is burned in for many hours then compared to the one that is not, then there is an obvious difference in how they sound, but their measured responses are the same as they were before in regard to output level.
