Thank you Erik for the info.. Anyone out there who can confirm that the Magico S5 tweeter is the Scanspeak Illuminator D3004/6640-00. The fastner holes seem identical but the Scanspeak has a grill over the dome.
So to clarify, Magico has always claimed their tweeter diaphragm has a proprietary coating which is a claim I would be unable to validate without having one of each.
My suggestion to you to think of this as a replacement was based on my understanding you wanted to be frugal.
If $800 seems reasonable to you, go ahead and get it from Magico. I won’t be offended. :)
I am however a little surprised they aren't willing to replace the diaphragm alone at a discount, seems a shame, since that really IS a very nice tweeter motor.
Best,
E
