SS dome, not ring, now a CD+horn, but this CD is essentially a dome. They sound very different.
My first concern after hearing the SS dome was the lack of "body" and power to the sound. Now this is gone.
I think that no perfect reproduction is possible, sibilant recordings sounds sibilant and that is right, it should be like that. But the difference is that I don't care a little sibilance here and there, because the whole speaker sounds so much better to me now, thanks to the new tweeter.
But I don't want to glorify it any further, because there are sure to be many who do not like this type of presentation, which is more forward but in a positive way, at least for me.
You may not hear the the sounds above 20kHz but those very high frequencies which are reproduced by a tweeter will affect to the other high frequencies(below 20kHz reproduced by the same tweeter) at that moment.
It might make sense, we see some designs with 2 diferent tweeters
, again: aberth, Dali... or speaker with one tweeter but with high frequencies low pass with a first order filter, Zu, Dunlavy... don't care too much of frequencies above 15k or 20k....

This all look good with the DXT from SEAS:

But Heissmann says that it "widen" around 3Khz unless in a narrow(non existent) or very wide front baffle...hmmm.

I, m not a specialist of anysort, but the little peak between 6k and 7k cycles may be harsh according your room and personal tastes,
I would prefer tje vifa peereless 26 gt, horned too.

yup... but it's driver related - a linear distortion, so I should be able to lower it/flatten it a bit with my filter and then everything should be ok 🙂
I'm more thinking in terms of Seas and Heissmann claiming that this is the only tweeter like this. Can that really be true?
