anyone heard these? what have you compared them to?
have you compared the Be to the DMD versions?
 A couple years ago I heard a pair of Mini Dancer 2s with the Be tweeter at a specialty audio shop. In that particular audition I compared them directly with my old ADS L1290's and Revel F32s.
Of the three the Ushers had the best imagining (very impressive) but I prefered the tonal balance of the ADS and Revel.  To my ears the Ushers sounded a bit "too warm" compared to the ADS and Revel which sounded more neutral to me (keep in mind this could have been due to setup/room issues; I was in an unfamiliar room with unfamiliar equipment).  I do remember liking the Be tweeter very much.
I ultimately ended up buying a pair of Salk HT2-TL which to my ears are better than the Ushers.
Of course, speaker preference is so personal so I strongly encourage you hear them for yourself (they certainly are worth considering).  BTW, why they call them "Mini" is beyond me, they are 
not small speakers!
Hope this helps.
