Over the decades there have been many (to say the least) loudspeaker burn-in tests. Some were measurement tests and the others were listener tests.
In the listener tests, they would start with a matched pair of loudspeakers. Then put one in storage and burn-in the other. And you guessed it, they then still sounded the same.
