I gre out of Be Tweeters

Ultimately a large percentage of the final sound all comes down to implementation.  Even Be dome can sound very natural if implemented properly.  Inversely, one can have a pair of speakers with soft domes that can sound harsh and unpleasant if not properly implemented.  

If you could afford it, diamond tweeters are probably the best. The one from Seas costs around $7K each. Ouch but I wish I could get my hands on a pair :-).

If not, then a high end soft dome from ScanSpeak or Seas can be very good. Good soft domes nowaday (those costing at least $200 or more) really offer the best of both worlds - speed, detail, but with the sweetness that we usually associate with typical soft domes. The ScanSpeak AirCir or Seas Crescendo are actually some of the best in the world. The Crescendo is a bout $350 each and the AirCir is about $200 - $350 depending on specific variation.

Ceramic tweeters may have a lot of details and may have less distortion but I don’t think they have the speed of the soft domes.

I haven’t heard Be dome personally but yeah people say they can have too much detail if not implemented properly.

A good tweeter can elevate the sound to another level.  Of course make sure you have some decent caps for the tweeter xover.

Change to Maggies and you will feel much better at the bar, I promise!

Hm... Interesting  because I've listened to couple of Maggies and they lack the details of the conventional drivers.

I agree you can make a pair or triad of drivers sound bright, or dull or bassy or boomy with the crossover, but I also think drivers can bring a lot of character to the design.

I was speaking of drivers that don't have any inherent issues.  Of course, if you have some garbage drivers then there are only so much the xover can fix.

Salk uses a SB Acoustics Satori.

Not quite as good as the ScanSpeak AirCir.  I've used both and the AirCir sounds more 3 dimensional.
