What our brain preceives isn't always what's real. But then you have to ask yourself the question, does it really matter?
If we hear the speakers change after 20 hours, does that really matter? The fact of the matter is that for a lot of people, after listening to a pair of speakers for several hours they sound better.
The only fact that should really matter is that speakers tend to be more enjoyable after you've listened to them for a while.
