Experience with separate super-tweeters?

At my age, I'm stone deaf above about 9kHz

That must be due to all that cheese in your ears

In an entire hobby made of toys, these are certainly one.

Historically, many speakers have hit the market with rear firing tweeters.

Back in the day, a big selling point for Merlin speakers was their rear firing tweeter.

Snell, Von Schweickert, Magico, Vandersteen, even those cray cray pricey MBL stacked Radialstrahlers toss an "ambience tweeter" up top.

You can stick one on the back of a speaker, or on top facing toward the back, or even up top firing straight ahead or up to the ceiling and simply see what your opinion is!

They can very very very! (!) room dependent.

Dirt cheap on Amazon for those "bullet titanium" babies, but for under 30 bucks you can toss then her or there and get a sense. They seem to add "information" for really narrow dispersion tweeters. Sometimes, these new fangled ribbon tweeters can seem to disappear when you stand up, so they sweeten the ambiance or the room for you.

No universal claim here, just playing with another toy and acquiring "empirical experience." No theory implied.

Would It be to loaded to call It "dustbin of history"?

I'm unclear where one sets the cross over to their tweeter that tops out at 20k say.

I do the XO for super-tweeter in upstream DSP-EKIO plus one tuning high-pass (low-cut) capacitor; you can modify these depending on your prefered XO Fq.

My PC-DSP-based multichannel multi-SP-Driver multi-amplifier stereo audio setup with super-tweeters FOSTEX T925A would be of your reference, I assume.
Please refer to (and read through it very carefully) my this post #774 for the latest total system setup. Here, I copy-paste just one diagram, the total signal path;

To be honest super tweeter's seem rather irrelevant these days when any competent speaker can go higher than most can here, just another complexity and expense in my opinion. If the very top end isn't of high enough output, I'd rather look for something with more in that sense rather than have to buy a separate tweeter.

BTW, we, myself and @617, recently had very interesting discussion on the thread entitled “Are Super tweeters worth it?”; you would please carefully read our posts #43 through #61 on that thread.

That discussion guided me into a new series of audio experiments on reflective wide-3D dispersion of super-tweeter sound using random-surface hard-heavy material. If you would be interested, please visit my post here and posts thereafter.

I am going to try a pair of Aperions soon. In case you wonder if there is anything happening in the audible range, here´s a short demo.

By the way frequency range on paper means nothing without frequency response. If your speakers sound rather laid back and / or confined the super tweeter might add a sparkle at the top end.
