Do speakers need to be re-broken in?

I recently purchased a pair of AER BD-3 drivers and was told it could take over 100 hours for the paper cones to loosen up and settle in.

AER BD 3's are really nice full range drivers.  Do you have any specific plans on how they are going to be used?

If the speakers sat for five years they might have stiffened up a tad, but abut a few minutes of play should be more than enough time to bring them back. 

Thanks for the responses so far. I was considering being one of those OP’ers who start a thread and then you never ever hear from them, until their next thread- but I am not that type of person.

Again, new driver break is not being debated here, that has basically been concluded to be required by manufacturers, and most of our ears have accepted this to be a fact as well.

The speakers I have in question have Lowther drivers which from the Lowther USA rep require 300 hours of break in.

And yes of course my ears are being adjusted to the new speakers and their different presentation, and I am still playing around with setup positioning, and getting over a cold where one ear was plugged is also a definite factor.

My question was after 1000 hours of playing, then sitting for 5 years, should they require additional "loosening"? I am going to come to the conclusion of a "few hours", as some have suggested, not to mention the single capacitor between the Lowther and the tweeter may require a little juice to restabilize seems plausable as others have suggested.

Wouldn’t surprise me. Hell, my Maggie LRS sound better after an hour of playing if I don’t use them for a few days. Could be just my ears but I have noticed this numerous times.
