Ribbon tweeters...out of favor these days?

Ribbon and ribbon-like tweeters are "faster" in that they can produce extended ultrasonic frequencies. The questions to ask are, how important are ultrasonics, and are they in the recording?

Ribbons/planars typically have a rising response or peak in the mid/upper treble. This response is often favored by those with some high-end hearing loss.

Ribbons typically have higher levels of distortion, interpreted positively as detail and speed, or negatively as etched and "too hi-fi."

Weseixas RAAL Raven are all ribbons.

Thee debate of Ribbons and Domes they both have their +&-
The new Raal Amorphous core is the best ribbon out there they have the actual specs avaialble on their page which have been verified .Very clean fast and dynamic .
I have compared these to a great tweeter such as the hand made Hiquphon tweeters which are only 3/4 " BTW Salk , Devore and a few others use them .In the past fried used them they are super balanced with superior dispersion.THe dome especaily these are great even 60 degrees off axis ,were a ribbon is much more directional .The smaller tweeter does not have the range down to 2k but with a good mid driver to Xover at around 2.5 k that is not a problem great dispersion and under .5 distortion per matched pair.
The Ribbon is more airy and open and inner detail is a little better .For rock and roll the dome is clearly better
mainly because of it's more flexibility off axis and imaging can be slightly better on the leading edge with a dome , it all comes down to preference and implementation of the Xover and drivers used in the application.
The Raal I think is slightly better than the best dome for my taste ,BUT that is my preference .

Well put Audioman...

There are other tweeters that have much greater range such as the Accuton BD20-6-031 3/4 " diamond tweeter frequency of 2500 HZ- 80KHZ.

And you pay for that performance in the product application @ $2900.

Prefer the ribbon tweeter for more open and inner detail for instrumental music and listening to percussion. Would love to AB higher fabricated dome tweeters against higher end ribbon tweeters.

one tweeter that is becoming a fast favorite is the Mundofr
AMT - Air motion transformer tweeters These are byfar the best the 2310 I may be using soon it is solid from 1khz to over 25khz .Don"t get to hung up in th numbers the raal will go out past 60k Bug deal it is ambiance possibly 1-2%
on the best of days .The amt tweeter is very fast and airy but also far more dynamic than a ribbon and very musical
more real sounding .retail about $1k a pair the raal is around $600+ if I am building or buyng from a company such as salk or Selah that builds cutom this is what i am using also to complement this Mundorfs excellent capacitors the Silver metal oil caps with their resistors it is a fantastic match for the highs and mids .
