how does one make a super tweeter

You understood correctly. This message is about: what tweeters to buy (tell the manufacturer) in order to make (make for yourself) supertweeters.
I have a Diatone DS-90C acoustics. It has an operating frequency range of 20 Hz - 20 kHz. I want to expand this range to 50-60 kHz with the help of a separate super-tweeter (I no longer dream of 100 kHz).
And the problem is that I cannot find such tweeters. But maybe I haven't fully explored the DIY tweeter market. Therefore, I ask you to suggest in which direction to dig.

Here are the tweeters I found, but they are all up to 40kHz. Are there no higher frequency speakers already? 🙂

The foster that’s on clearance from parts express has been used by adason in a build and he liked it……for the money I’d say that’s worth a try.
I just picked up some heil amt II to try in a super tweeter configuration but haven’t got to setting it up yet.

its like looking for a subwoofer that play flat to 3Hz. It has no real purpose in audio but you can definitely find fans and blowers that can rotate and push air at 3Hz so maybe you just need to look for other transducer types than loudspeakers. speakers are electromagnetic-acoustic transducers but you are looking for something else, 30-100kHz ultrasound you are entering AM radio waves so maybe get a radio antenna but we are slowly entering the domain of 5G paranoia and psychology here, wear foil hats before using super tweeters folks, if you find all the house insects on the floor maybe sell it 😉

As a test, insert an EQ into the signal chain and have someone else turn down the 20kHz band until you can hear a difference. Tell them to stop at this point and see how many dB down at this frequency you could hear the sound changing. Repeat ten times and average the results.
We all know that a square wave requires an infinitely high frequency response to create an instantaneous rise time of the leading edge, but I have never found any credible research which found that inaudible frequencies are necessary to create audible differences in transient sounds.

I did a search for designs that use the DX 25 and found two. Maybe one of these would work if you use a variable resistor to control the output.
I'm curious to hear your opinion about any difference it might make.
Mike

super tweeter benefit is to combat beaming, then the extension of the frequency
while those you listed may have extension, many are beaming too soon
last two examples start beaming at 800Hz! just look at their of axis response

Interested in the frequency range from 14 kHz (I don't know yet what the lower frequency should be. I assumed it was 14 kHz, but maybe it should be even lower.

Greets!

~ 6 - 40 kHz, though ~22 kHz is highest recordings I'm aware of.

Historically, Altec or similar 1" compression drivers frequency shaped [Eq'd] from ~ 3 - 22 kHz, typically XO'd 5 - 7.5 kHz; otherwise frequency shaped [Eq'd] cone or piezo horn tweeter array.

This is funny. 🙂
Yes, I want esotericism and mysticism, but it's interesting. 🙂
Have you heard the story about the Russian "Lefty" who shod a flea? I've always wondered: what was this dude's ultimate goal?
Now I am such a "Lefty", the ultimate goal is not clear, but I really want to do it.
