Magico V3: Metal dome tweeter

I have a question on the V3. I noticed they were in a demo with SimAudio at Guangzhou last year. That's a bit of a departure from the usual Boulder, Tenor or Soulution electronics.

By any chance, has anyone heard this combo?? Thoughts?

Thanks. A friend who I spoke with earlier answered the question for me. He said it was a soft dome. The bullet plug on the Revelator confused me a bit since it is metal. Actually, I should have specified super Revelator.
