damn, they look good!
14€ per piece is a really good price.
but i realized that you american guys are even more lucky with the current offer from parts express: 10.80$ if you buy 4 or more....unbelievable!

They do look pretty nice - the paper cone is treated with a satin coating that has a nice look - probably part of the reason it sounds so smooth. The only thing I wished they did was to mount the foam gasket on the back rather than the front.
Serious experimentation with 12 Aura NS3 and 2 Peerless 10":
An externally hosted image should be here but it was not working when we last tested it.
Attachment to baffle probably not as difficult as with your build.
BTW, there's a third lesser-known sibling to the TC9 and TG9 siblings - a woven Kevlar-cone 6-ohm 30W unit from Tymphany (which is the OEM for both the TC9 and TG9 also):
Tymphany TYPY03W06O0111 3-1/2" Full Range Driver

It hasn't generally been available since 2009, but surplus lots do surface from time to time. It's similar to the TG9 in overall sonics, but with slightly higher Fs (123 Hz vs. 110 Hz of the TG9). I've tried it in a folded MLTL similar to the Tabaq, and it works (you lose a bit in the lows, and gain in the mids):

Of course, it also works in small sealed enclosures for HT/satellite use, which may have been the original market for these beauties - the mid-range/vocals are worth dying for, as I hinted earlier:

It hasn't been available from Parts Express for some 4-5 years, but other surplus sources still get stock from time to time. Look around on AliExpress, EBay and so on - I just snagged enough quantity locally to build several line arrays if needed.
Is the top end decent on those Kevlar coned Vifa's? I noticed PE had them cited for 123 to 10500 Hz.
That spec would make them more of an extended midrange speaker...
Any measurements to be found around the net?

It's a matter of subjective opinion - My hearing acuity probably doesn't extend beyond 12 kHz, maybe lower, so I find its highs perfectly adequate. Others may want a small helper tweeter or similar, crossed high (maybe 10 KHz).
The mids are indeed its strongest point - vocals are a standout.
Actual measurements from sample units: I've shipped a few units to folks with Speaker measuring setups, so there will hopefully be some measured numbers in a few weeks.
It also doesn't have the x-max of it's polymer siblings...
1.6mm compared to 2.55mm on the polymer basket versions.

Also that driver has a fabric surround rather than rubber. I have been listening to this driver https://www.solen.ca/documents/pdf/peerless/tc8fd0004.pdf I think I like it more than the tc9fd, it is 4ohms.

Fs is also much higher at 175 Hz - compared to the polymer-basket versions which range from about 110 to 123 Hz, which comfortably allows quarter-wave MLTLs with bass extension below 60 Hz.
The application is explicitly stated to be Line Arrays, but some kind of subwoofer-assist seems to be necessary for the steel-basket version.
The paper-cone, polymer-basket TC9FD is probably the best sounding all-rounder, but the Kevlar-cone, polymer-basket TPY03W06o can handle 30W rms at 6 ohms impedance, which is a very versatile spec for small gainclones, Class-A, Class-D, Tripath, line arrays, HT satellites, soundbars, etc.
There is also a 12-ohm, 30W variant called the TPY03W12o0102, which is mainly geared for paired-driver, 60W full-range setups.
I don't fell that measured distortion is that important, even thou distortion in the global sense is. Often a multiway will not have as good a dispersion characheristic as a good full-range.
Multiways can go lower & higher & usually play louder than a full-range. They appeal to many humans that like to say "mine is bigger than yours", or more is better.
Personally i think a woofer assisted FR is the best set of compromises between a FR & a multiway if some of the advantages if a multiway fit the mix of compromises that best suit you.
