HOLOGRAM,
there is definitely a break in period for the speaker itself. i find speakers never sound the same out of the box as they do a few weeks later. It's like a pair of shoes, they need to break in a little. you must also not forget that, in the store, they usually have the speakers set in ideal conditions, and hooked up with some very high quality equipment. they also have the seating position of the listener in a very good position to hear the speakers properly. this definitely contributes to why speakers sound better in a store than they do at home right out of the box.
