… as some friends call the high frequency/ super tweeter on top of the BV 8X by TAD/Exclusive. In fact it looks like a species from a different planet. Does it sound like that?

Yes and No!  But it is hard to describe as this 4 way horn system, including a large field coil bass driver of SupraVox, provides so many possibilities catering to the needs of the listener.

I was advised using the Fostex attenuators for adjusting the three TAD drivers. – a good choice!
