You like ribbons, good!

Lets not mix that up with absolute performance and SPECIFICATIONS!
Which the discussion is about.. please remember that.

"Useful output detectable to beyond 50k Looking at quality domes like Vifa etc. one is lucky to get to 40k and that is on a good day"

If we discuss tecnologies, lets look at the best designs. There are numerous dynamicall (non ribbon) tweeters that extend to 40-100k. Do yor homework ;-) (ex. Focal, Accuton, Technics, Scan Speak).

"Then look at the moving mass gram weight. Domes are often 25 plus times more. "

The moving mass itself is totally not interesting. Lets look at what the combinations that goes into the design does in the end.

"Wonder which moves faster?"

"Fast" is totally irrelevant. Look at BW, the only interesting thing. You could argue that the transformer often used in ribbon designs limits the "fastness" of the design, which leads to a dome with 60k respons is "faster" than a ribbon with 30k.

"The ribbon tweeter cost much more than the dome to be sure."

Cost is absolutely irrelevant in itself when we talk about specs. That said I believe the most expensive tweeeter is the Accuton D30.

"Compare the build and it's a no brainer"

What has the "build" to do with it? Let´s stick to specifications and important parameters for a accurate transducer.

"When you get the chance, find a quality speaker using a true ribbon transducer tweeter. Sit in the sweet spot, put on your favorite music and close your eyes. You'll never go back to a dome again... "

I have listened to a couple of ribbons but not sure what makers those where. Very good but not the best I´ve heard (different set ups, different rooms). The best reproduction I´ve heard of high frequencies has been from the diamond tweeters. They extend higher than most ribbons and have lower distortion. On a budget, I would not be totally surprised if ribbons sometimes is the right choice but lets not mix that up with absolute performance from the respective technologies.

Happy listening!
