It's marmite. Several people think it sounds weird and bad. You can search for more. I had it in a 2 x 5" MTM (one of the designs mooted for here) and just don't like it and think there are plenty of better choices. I don't understand why it's so hyped up.

Wouldn't the 22TFF fit the waveguide on its own without the D2010 chamber? Could be a contender (Spendor uses it for Classic range + also on some Diapasons) as more sensitive + cheaper OW1.

possible to stay on topic, please ? (cut off constraint, budget and on the shelf unit)

@diyiggy , if you prefer to spend whole budget for max performance and it should be soft dome
then I would say the TW29RN-B-8 is your only choice, pretty much.
then I would say the TW29RN-B-8 is your only choice, pretty much.
I sumarize and within the budget members inputs about a standalone favorite choice :
Morel CAT378
SS HDS
SB-A TW29R or SB29RDC (less good iirc than the former)
SB-A SB26CDC
Seas Titans (27 TAC/GB) : sensitivity too much low for my needs >90 db/2.83V & WG not possible IIRC dur to the face plate.
Wavecor TW030WA12

I'm noticing 28-30 mm tweeters getting more favored in high-end world (Magico, Sonus Faber, Dynaudio, others)
Maybe that's the key to a more faithful rendition of (lower) highs

The Seas 22TAF IS a greeat sounding tweeter! Can even be crossed over way deeper as 3kHz (at least active) but doesn't get really loud.
Bigger tweeters are modern cause - membrane technology got better! Look at Blisemas 34A - resonance frequency in the 30kHz area and wider dispersion as most 25mm tweeters! Comes with a price ... but not to long 25mm meatal tweeters had their breakup at 20kHz or less and sounded exhausting.
When you want to get all lthe stuff right you describe here ... you will probably need a little more money. With every description I read here I think "Beryllium" ... 😉

I really wish Troels had not called them "super-capacitors", as that is a name for high capacity power source capacitors, and has been for a long time.
The more usual names are "bifilar-wound" or "double-wound" for those such as Mundorf Supreme, Audyn Plus, Plastic Capacitors LQ, and Jantzen Z caps. It makes them inherently non-inductive.
I kinda went overboard with that comment
I really think there's little point in going beyond Superior-Z.
That was his go to cap for Level 1, even though there were better caps from Mundorf etc
Then Jantzen introduces Alumen and Amber and suddenly he can't help by going Alumen for midrange high-pass.
..... ..... .... a man's gotta make a living, i guess

If it does not specify I would assume its acoustical since that's what actual counts, I am not 100% certain however.
If you're thinking of the Seas, Scan etc. data sheets it's usually purely for the purposes of the various IEC (or equivalent) power-handling test conditions -most often B2 @ 2.5KHz. It's not a recommendation for a crossover frequency or slope. Or not exactly -Scan do often use that frequency as a 'safe' low-range recommendation for tweeters on their data sheets, since they're less likely to get a slew of warranty returns: the inexperienced will probably choose that and be relatively safe whatever they do; more experienced designers may select something different, but be aware of the balance of compromises they're working with and are less likely to blow the driver as a result (or blame anybody but themselves if they do happen to release the magic smoke). 😉

had anyone listened to the 2604/83000 (aka the clean DX25) ? So not the double magnet one and with no arrow on the dome ?
I like what Dibirama but no one talk about that one but Heeissmann acoustic iirc...

Because it's on old version!

i think the hds is a very nice tweeter, one of the better low cost tweeters. All naked ring radiators i have heard do sound aweful, the lack of dispersion in top octave is a serios design flaw, the engineers as solved one issue and created a flaw that is more problematic, and people by and praise this crap
I initially wanted a compression driver in the share ware mabatt WG but having a 5" mid between the 12" for the mid was the way I chose in the long list of trade offs, as a MTM but juts for the efficienty (the 12" is a PA : 12PR3220) to follow the 12" that have around 91.5 dB efficienty around 100/400 hz.
Barefoot use a 87.5 dB sensivity SS tweeter with their MTM with the drivers I chose : https://barefootsound.com/micromain27/
certainly tons of DSP and maybe the two M in serie (93 dB circa in //). With the 12p3320 I think to be nearer two 90/91.5 dB in the highs since a little passive eq and bafle step compensation.
I think a smoothly Harmann curve is better to me in living room situation hence the choice of > 90 dB for the tweeter for a cut off <= 2000 hz to manage a sligth bump and bafle step in the mids passive XO... grossly I mean.

Datasheet cot of frequency is electrical and normally used to get the RMS power rating. But have a look in the footnote of the power rating - could also be defined different there!
With active filtering 4th order I also already used lower frequencies - but after all the acoustical slope is the interesting one. When there is no K3 rise at high levels the frequency schould be OK.
