Let me verify - are you saying that more recent models have Titanium membrane
on the tweeters?
Not that I am any expert at materials, but I would think adding a titanium membrane over ceramic would be difficult (maybe they are using Ti over Al in lieu of Ceramic?). I also believe it would be a significant change in sound.
Have you or
@snakeeyes listened to a speaker with the Ti membrane tweeter?
Comments?
I am a little shocked that they would mess with such an excellent driver.
