I don't think they do...
or at least, I don't think they "should".
Ive always thought of the enclosure and driver baffles of a loudspeaker to be inert, and therefore indifferent (acoustically) to what they are finished with.
I have understood (perhaps in error) that this is not the case with very thin walled "acoustic" instruments such as guitars/violins and such.
