Mid & hf drivers must have some kind of sticky compound or dope to damp a resonance and/or smooth out response i guess.
Very musical & always fine sounding that's nice to hear, it means their implementation of a larger dome for the critical mid sound must have been a good idea.
Since you have other a/d/s & braun, based on the ones you have, do you confirm, as per the ad, that they share same drivers between ADS and Braun, or looks like they do?
OH! cancelled years ago.

They were 32. Thirty two bucks!!...
Btw they seem to have a large dustcap vs woofer size?
