It is all about a speaker sounding best to your ears or not. I have a psb Imagine XC sitting in the basement less than a year old. Yes, I do believe in speaker break-in......as have noticed a difference over time.

Anyway, again, let your ears believe what they hear, for what best fits. Measurements are measurements and can the human ear grasp every measurement a speaker measures............and you can hear in music??? :)
The music experiment was to test whether the tweeter is "blown" or disconnected, without opening the cabinet and checking things inside. It seems to work to some extent, unless of course the woofers/mid-ranges can sufficiently carry highs as well and the cross-over is faulty.

What sort of difference in the XC sound did you notice over time?

Also, see the speaker break-in thread, and watch the two video interviews of Andrew Jones of ELAC (at that time) on this topic.
