I see more gain in this than in using boutique crossover components or absurd heavy CLD enclosure walls…I don't understand why introducing a nightmare for production and cabinet/mechanical design, while the gain is so little?

With this simple circuit...
...and the latest REW beta, the FSAF measurement method allows for one to run this measurement with real audio, and listen to the residual distortion produced. No microphone required, just a soundcard, a resistor and a patch cord. It's not exactly the same as an acoustic measurement, but still provides a lot of valuable insight into driver performance, and enables comparisons between drivers, and various filters or even cabinet arrangements.
For a simple example, a recording of a Wavecor WF120BD04 is attached, tested at 2.8V free air. You can hear easily the harmonics, intermodulation, and barkhousen snap,crackle, and pop.
If there's interest in further discussion, perhaps a new thread can be created instead of clogging up this one.

I have some time tomorrow to download the rew bèta, and will hook it up in the connection of the midrange of my active 3-way system.

Wondering why HD3 and HD5 seem to improve (relatively) going from 4 V to 5.6 V, in region of 800-1500 Hz? Based on your comments, it seems the higher LPF only kicked in at 11.2 V?
No one knows why this happens. Please do not take into account the exact values at some points, but look at the general trend, especially when we analyze the behavior of soft dome tweeters 🙂

Please enlighten my simple mind, what is "DF"?... that changed DF!?
I may have some more detailed review of this simple measurement with sine sweep FSAF and some various drivers. It will take a few days to assemble, so stay tuned.

Uh, looks bad >10 kHz to me; breakup peak, narrow dispersion. Distortion peak around 4 kHz looks also not so well. Only good thing is it can go loud.
In comparison with other neo fabric dome tweeters, Wavecor TW030WA13/14/23/24 or Scan Speak D3004/602200 show much better and nearly flawless behavior.
P.S.: Thanks for the measurements! 🙂

I really like this driver! Good sensitivity, good THD at lower frequencies, great frequency response and as low dampening as they could do (seeing first hints of resonances but still very little).
Would be my choice when not using a mid dome and "normal" SPL levels.

Many thanks as always: very much appreciated, & (also as always!) I hope you & yours are keeping safe and well.The Satori MR13TX-4 5" true midrange TeXtreme cone speaker review:

But Txtn is maybe also less colorfull than paper, or the strenghened ones like papyrus. Certainly a good trade off over metal ones surely... Some found the Perlisten loudspeakers full txtn to be a little boring ...
Devil advocate here as I didn't listen to a txtn. I am not sure it is more enjoyable than a SS 12MU, NE149W, Satori paper... but certainly more accurate for pro mixing ?

Just a question, if the tweeter impedance due to applied power rises from 3 ohm to 3.5 ohm, how much spl loss does that imply?
Thank you for the review.
In that frequency range : how compare the sound of Textrene VS PP doped Mica à la Audiotechnology or Hivi, please ?
Also some testimonied textrene tweeter sounds a little similar to true ceramic tweeters, what is your listening experience about that?
