@djnagle What information are you seeking? You didn't really ask a question in your first post. It was more of an announcement.
I have owned Shahinian Obelisks and recently purchased a pair of Hawks. I have not owned the Diapasons. I find that Vasken Shahinian and his team are very fair and straightforward. I had Shahinian refurbish a pair of used Ob 1s that I purchased for a song but needed a lot of work. I couldn't have been happier with the results or the price. Well... I guess that they could have done the work for free, if they really wanted to impress me 😁
But seriously, if you think that any audio component should be judged priced based on the raw cost of the components (even assuming that you have correctly identified this $20 passive radiator) then I suggest that you should design and build your own speakers.
All that aside, how can we help you?
