Seas Millennium Break-in time

Hi I just bought some new Tyler Acoustics Signature Monitors .The Seas tweeter is supposed to sound a little on the poor side until about 200 hours. Is this speaker(which is on it's way) really that bad until the 200 hour mark or is it not bad out of the box but improves some over the next 200 hours? How would you recommend breaking them in...playing them around the clock for 8 days at a moderate level or infrequently over two months or so...at a louded level? I am looking for a time & level that is best & what to expect out of the box. Tyler claims he player the speaker for 24 hours to ensure everything was operating properly.

Thanks

Bill
