Cdc-- I may not have communicated enough details. All metal dome tweeters resonate. It is inherent in their physical properties. The research found resonating frequecnies at 20kHz. This does not mean that this is the only point of resonance. Most start at 20 but really begin to ring at the 23-26 range. So, the B&W is right in the middle.
I will see if I can get a copy of the preliminary findings and methodologies and post it.
