Ribbon midrange pros and cons

RAAL makes ribbon tweeters  
  
Companies like GoldenEar use AMT tweeters, they look similar but are different tech.  
  
The RAAL tweeters are some of the best on the market, but they don’t make any midranges, and I don’t think I have ever seen a ribbon midrange, probably because those frequencies require much more air movement.

Those are AMTs not ribbons.

The BG Neo planar midranges are real good, Philharmonic uses the Neo 8 in their tower speaker. http://www.philharmonicaudio.com/phil3.html

I also saw it being used in a speaker when I went to the Florida Audio Expo.

No clue on distortion, but it’s imaging/soundstage is excellent for the price, very glad that PS Audio is considering them, it looks like they are using the Fountek NeoCD3 for their tweeters, which is also a good choice, obviously not as good as say a RAAL 70-10D, but it is of course around 1/5 the price.

EDIT: Going off this image, it looks like the tower is using this Dayton tweeter, which is still efficient and has good imaging/soundstage, but I guess/hope it’s a placeholder and not the final choice, as it would be odd to use a different tweeter for the bookshelf and tower (you an see the bookshelf in the background with the Fountek tweeter). I also can only see the bookshelf woofer as being a KRK or HiVi one, as hardly anyone is making yellow woofers and I doubt Paul requested for the cone to be yellow.
