Dmitry,
These things are incredibly hard to find in the usual quality vendors. 🙂
Here's the one that Parts Express has.

Found this at Gravesen's site.
I love this quote... "Last but not least, high-efficiency paper cone tweeters are becoming rare as hen's teeth these days"
Hahhaa.

DIM, thought this might help....96 dB. Hmmm don't know about that, but anyway.........

DIM,
Can't remember when I listened to speakers with phenolic ring tweeters, but I would not be afraid to try one in a classic 3way build.

The question of sensitivity, the tweeters themselves are inexpensive, but the delivery from US to Russia can bite ...

Wow! I wonder if it's true.
What do you think about the old "phenolic rings"?
You wonder if a 96 dB spec for a 3 dollar cone tweeter is true?
That tweeter on Chokes Unlimited is the same Erik mentioned.
If there is anywhere decent enough cone tweeter then from Visaton.
Not what you're looking for but it is what it is. One question though.
How do you know that you need exactly 94 dB tweeter for your
high sensitivity project? What are the other drivers?

Other drivers 6ГД-2 and 3ГД-42 old soviet's. Both in working bands have a sensitivity NOT LESS than 94 dB/W/m. I have access to a certified anechoic chamber and measuring microphones.
If this is the speaker you are using for your project then
it looks like other vintage speaker units with high Qts
and I seriously doubt that it will have a sensitivity in a box
and with a XO filter anywhere near 94 dB/2,83V. If you get
it to be 88-90 dB you will be very lucky. Modern high quality
12" PA drivers with powerful motors may hit 94 dB/2,83V.

I am lucky, believe me) All my drivers are measured and are just waiting tweetrs.
I do not ask for advice in the construction of the speakers, I'm just asking about the cone, paper tweeters.

Oh, I see! Would you happen to have measured TS parameters
of your woofer 6GD-2 and the frequency response graph made
with a calibrated microphone and put it here, if it's not too much
to ask?

Sorry, if you write on this forum, I think you are quite capable to make measurements on their own. No one should do that for you.
I think these are graphite-coated paper cones but I also think they stopped making them so old stock is all that is available.
Not cheap either...

You are right. I would do that if I had these drivers at hand. I don't, so
I asked. The picture of the woofers was googled out. Thanks anyway!
Especially for You I'll post in this thread or will create another, photos and measurements of the finished speaker. I promise. If it will be interesting, and the filter circuit. But this is not a quick process.
