Temperature and relative humidity can have an impact on various materials used in loudspeaker drivers.
For example, if a speaker is stored in a cold warehouse for a few months prior to being shipped, the internal temperature of the cabinet will have dropped well below the ambient temperature in a typical home environment.
This might take a few days to equalize, similar to thawing out a turkey.
Playing dynamic music through the speakers will help speed up the process, and will flex the spiders and surrounds so they reach their nominal compliance.
Electronics shouldn't be subject to mechanical factors, but there might be some kind of audible electron flow phenomenon, though I doubt it.
