Sounds good Jeff. I'd like to see how the B&C mid looks in your simulation. As far as target sensitivity, at this point I see now reason not to try an approach what you were able to do (93db, I believe) in the Salk design. A little more might be better, a little less ok also.
Yes the Peerless HDS was one of the three tweeters I initially identified as candidates early in the thread (you might have missed that). They included:
Seas 29TFF/W (H1318, 92.5db: $44
Peerless HDS 810921, 93db: $78
Peerless DX25TG05-04, 93.5db: $28
These are well known and well tested, low distortion tweeters. All seem to be able to cross fairly low with Fs's below 1000Hz.
Here are a couple of long shot possibilies in the dome arena that Zaph has on his bench to test and are also high sensitivity with Fs around 1350hz. These are very inexpensive neo tweeters, so I don't have much hope for them though the rated sensitivity is quite high. Perhaps Zaphs testing will tell us the a bigger part of the story on these.
