This widespread perception about metal tweeters is crap and has taken on the status of audiophile myth along with direct drive turntables and MM cartridges. Metal dome smoothness depends on how the dome is damped among other things. I have a low tolerance to harsh treble, but my Mirages have a treble that's sweet as silk--powered by titanium domes. They use a cloth suspension to damp the tweeter and it works. Because of the light diaphragm and titanium's resistance to breakup, the titanium tweeter is both articulate and very smooth with no artificial high treble boost or edginess.

That said, there are lots of great fabric tweeters as well. It seems the Nola Boxer would be a great choice for the OP's criteria. Also, GoldenEar DOES make a pair of monitors, the AON 2 and 3, which are stand-mounted and use a most excellent Heil-inspired folded ribbon tweeter.

The Dynaudio Excite X12 or X16 should work well and are in your budget. This Stereophile review of the X12 indicates that even the X12 has room-filling projection, unusually good bass for such a small speaker (true usable bass to at least 40 Hz), and the review makes particular mention that it stays clear and articulate on large scale classical orchestral/choral pieces. The reviewer loved its midrange and listened to a lot of female vocalists as well.

The Focus 160 (their next line up on the quality scale) is reputed to be significantly better but I think it's more like $3K.
