Good new year to everyone.
I have been learning about HI RES audio, and I have understood the influence that ultrasonic harmonics have on audible frequencies, making us appreciate details and subtleties that recordings have and that we would not otherwise appreciate.
I have also understood that for these ultrasonic harmonics to be present, they must be present from the recording, to the speakers, through the entire audio chain.
Thus, having speakers that are not suitable for HI RES, that is, they reach 20khz, I have thought about adding membrane super tweeters, which reach about 40khz.
Of course not adding it to the box of my speakers so as not to damage them, but rather in its own box superimposed on my speakers.
Would this be effective to transform my boxes into HI RES speakers?
Greetings

Sure, but can you hear past 17kHz?
There are those super expensive super tweeters, for thousands of dollars, and there is one small cheap foster planar which beats them all.

Several of my audio friends are experimenting this idea, with horn or ribbon tweeters... I did not listened to it for the moment. It probably could work as you expect, but these super-tweeters are rather costy units !

Could you tell me where to buy those cheap ones you mention?
Regarding whether I would hear more than 17khz, of course not, but what has been explained to me is that you don't necessarily have to listen to those harmonics above 20khz, but rather what those frequencies do to the audible frequencies.
There is an electronic engineer who uploads videos on YouTube who in a video of about 4 hours explains it very well, even with measurements in oscilloscopes and spectrographs, where he shows precisely the modifications that the audible frequencies undergo caused by ultrasonic harmonics.
You are looking for it through Crino Audiophile.
You will have to use the automatic translator since it is in Spanish.
I appreciate if you tell me where to buy that cheap planar.
HiVi planars are very large but cheap. 😎
I have a Fountek NEO CD3.0, but as a tweeter, cut with a second-order filter at 5kHz. I also tried a lower cut, 3.5kHz 3rd order, I didn't like it.

Search on Aliexpress/ebay for a planar tweeter, there are a bunch of cheap ones to try. Pay attention to the frequency range, the ones I suggested go up to 40kHz (if they don't lie a lot). After that, something more serious can be taken.
HEAR vs PERCIEVE >
I feel lucky that in my 'older' age I can definitely hear 17Khz,
but 18Khz just seems like a 'pressure' I can perceive. 20Khz is gone 😕
However, 20Khz is still something I want to see on my mic./analyzer.

HiVi is really big one, 176mm diameter. I have Visaton G20SC too, it works up to 30kHz. Excellent little tweeter. Fountek ribbons CD1.0, 2.0, 3.0 have wide horizontal dispersion, but narrow vertical dispersion. CD 2.0 is exceptionally good tweeter, and not too expensive.

Darn cant find the foster and now that i've seen its response, looking for a supertweeter for a while, can't seem to be able to do without xD. Something else that already sounds the most 14 K - up?
Using some piezos, i usually end up with some awfull sibillance, 8-11 Khz related that's really hard to get rid off... As i save my biamping for the sub.
And also yes, in the end frequency is a measure of well, frequency. Lets put it this way, if i could strike your skull with a microhammer at a frequency of 20 Khz, i believe you would must surely feel it. If that excitation happened in the mastoid part of the temporal bone, you may even loose balance.
Music seems to be focused on High low freq content to achieve some vibration of the body parts and maybe there is even a reason for it, other than home systems, as nobody can reproduce reliably 7Hz content in some music either.
Also, at really high freq, high res is a must

I've been working with calibrating microphones above 20kHz. The rather cheap Sony SS-CS5 speakers have a small supertweeter that pretty comfortably reaches 50kHz, and even has usable energy for comparison calibration to nearly 80kHz. Directly on-axis, of course. As you'd expect, they (and about everything else) beams badly up that high.
(And if you'd want to use the speaker for mic calibration, it actually goes better if you block the larger 1" tweeter as it interferes with the supertweeter and makes mic placement insanely touchy(

I’ve done this AB test last year……turning on and off blind Fountek ribbons crossed at 6khz……..there were 4 of us taking turns listening and running the test……confirmation as expected…..50/50….or in other words…..audiophoolery.
I think I know the Foster 'super tweeter' you refer to > a lovely circular aluminum driver with output up to 25Khz. (great sound)
Re. the Piezo side of things, have a read of this:

Regarding current 'off the shelf' super tweeters, at a good 'pair price' these are also worth looking at > noting impedance & XO ( I like them ) >
