FWIW, my main home theater speakers all have ribbon tweeters. They were made by VMPS, which is defunct after its founder passed away. (Sigh.) When I was looking to get "matching" in-ceiling speakers for surround sound, I ended up settling on a pair of these:

The dealer I bought them from set them up for me to play with, freestanding in their audition room. Seems cheesy, but it was "good enough", and definitely "matches" the sound of my VMPS speakers. When streaming stereo audio from the internet as background music, I have my amp configured to one of its modes that spreads the stereo sound to all five primary speakers, and this works surprisingly well.

Fun fact: I did some web searching, and it seems that BG Radia was bought out and is now also effectively defunct. So all the loudspeakers in my house are now from defunct suppliers.
