Despite what some have said, I actually like the Titanium dome tweeters.
BSW offers both choices though. Their silk dome option is a Rainbow speaker which is also German made.

For the money, it was a slam dunk. Again, my aim was not to create a rolling concert hall. I just wanted better sound from the stock system.
