Speaker break in?

I own German Audioplay five-way speakers. When I received them 8 years ago, they sounded just awful for several weeks: Bass was slummy, middles and highs shrill. All that went away with break-in, and they turned out to be execellent speakers with every kind of music. A year ago I put them away when I bought my first Shahinian speakers (Obelisk) - and later settled for the Shahinian Diapason. As the Diapason subwoofer is away with a restaurator to refurbish the wood, I plugged in the Audioplay speakers a month ago. Again, having had a good year's rest, they sounded awful. And sure enough, after two weeks of playing, they start to sound musically again as I write this.

4yanx, I would like to try that experiment but I can't bring myself to do it. You do it.

Oh, you sounded like you were speaking with the voice of experience there, Bufus. Actually, my post was left in jest. I could never do such to even the surliest of audio salesmen.
