how does one make a super tweeter

excellent super tweeter
I posted measurements and two speaker projects with these recently

Isn't this kid already better than the Fountek Neo X 2?
I still look towards the Fountek Neo X 2.
And it became very interesting about plasma tweeters. But there is very little information about them on Google. Only articles, but no specific model.

In general, I opted for the Fountek Neo X 2.0 tweeter. I think he should be perfect for me.

Now I have one more question: how to make a second order filter for this tweeter so that the cutoff frequency can be adjusted from 4 kHz to 16 kHz? Do you have any ready-made schematics? I would be very grateful for your help.

I found this interesting supertweeter filter at a Japanese auction. But the price is very inadequate. It seems to me that it is easy to do it yourself. There would be a scheme ...

A filter is just a coil and capacitor. You might like to flatten the impedance to have linear impedance. The filter is a bit trial and error, and you need to be able to measure.

Some help here, but remember text book filters are just examples

I bought these tweeters after all:
Foster E100T10 Planar Tweeter 8 Ohm
They will come to me at the end of August. 🙂)
I have to ask for your advice again, dear experts. These tweeters have frequencies ranging from 6 kHz to 40 kHz. Does this mean that there is no need to do a crossover for these tweeters?

P.S. By the way, if you want to laugh: I bought 4 of these tweeters by accident. I don’t understand how it happened. 🙂 There was an expensive delivery, almost 80 bucks, and I decided to buy other interesting things, and did not notice how I put 2 more tweeters in the basket. 🙂

The Foster E100T10 tweeters require a crossover of 12dB per octave at 6400 Hz or higher/steeper slope to handle their rated power.

Without a crossover, low frequency signal would destroy the diaphragm at far less than rated power.
