I'm close to pulling the trigger on a pair of Bliesma T34B.
Being a fan of other large dome tweeters ie. Audax TW034 and Seas T35-C002, these may be right up my alley considering how much xmax they have to cope with a lower xover point and still play reasonably loud. The specs and measurements look impressive as does the build quality, but they are ridiculously expensive and not easy to get ahold of in the US.
Anyone have real world experience with these drivers?
What do they sound like compared to other larger diameter high end domes?

They are the best measuring tweeters in their class. They can go louder/lower/cleaner than anything else you can buy with a 30-34mm dome. Nice dispersion in the top octave as well.
I've heard the Al/Mg version. I have no idea how the others sound but I doubt you'll find much to critique.

I'm very impressed by the dispersion characteristics above 10k. They must do something really slick with varying the dome profile and thickness to control the breakup mode and avoid phase shifts.
I'd like to hear the Alu version. Looks like a good alternative for the price. Still have my heart set on the Be version. Life's too short to compromise...

and oddly, the smaller T25B is rated 100w @ 2.5k BW2 but the larger T34B is rated 80W @ 2.5k BW2. Not that I'm reading into this much, but I'd expect the T34B to handle more given the larger VC diameter.
I have a pair of T34A's I'm ready to move on if you're interested. I've decided I have no need for such high sensitivity drivers here
Regarding tweeters that can be crossed over at lower frequencies, for the time being it looks to be a toss-up between the T34A / T34B, Wavecor's TW030WA11/12 (which combines an integrated waveguide with a diaphragm of slightly larger surface area than the Bliesmas), and Tymphany's DA32TX00-08 (no waveguide, but an even larger-area diaphragm).
Hoping that eventually there will be waveguides for the T34A / T34B and DA32TX00-08 that extend their lower range beyond what they can do now.

The price is really the reason for most of my hesitation. I've spent alot of money trying various promising drivers that ended being disappointing in some regard. I'm sort of done with most soft domes due to the coloration they add. I like the smoothness and for the most part freedom of listening fatique, but I don't like the blur and veil you tend to get. A really good hard/metal dome just sounds cleaner to me. The bigger Seas and Audax are a better compromise despite being soft domes, but dont have the top end extension I want. My reference soft dome is the Scan Speak D2905-9500. It does most things well, but my cheap Seas/Thiel metal domes with Ti formers just sound cleaner. They just don't go low enough for my needs.
Decisions, decisions....

As long as they won't sit on a shelf for years...go for broke.
Life is indeed short. Divide the cost by the amount of hours you can enjoy world class performance. It's not that much in the long term.
You can choose to run them on a baffle or have one of the smart waveguide folks print out a couple of waveguides.
I put a T34A through hell at PA levels. It survived sustained recorded playback at much higher levels than most households would tolerate. Sounded good doing it too.

Thats what I wanted to hear, assuming the similarities of the Alu version to Be. I listen loud and dont baby my speakers. I expect alot from them and as long as there's no noticeable distortion, I'm not shy with the volume. Most soft domes fall apart at higher levels. The TW034 and T35-C002 are my favorite compromise. I haven't killed a tweeter yet, mainly because I have common sense to not push it into audible strain.
I do plan on running the T34B in a WG. It just makes sense. Just trying to budget for the crossover parts which I don't want to skimp on either.
I use the T34B in a waveguide and the sound is impressive, please look at here:
Project 30 2 way 100Hz and up.
I also use the T25B in a waveguide in another project (my office sound system)

Both are very good in proper waveguides, but the T34B, if you are willing to pay the price, is a class by itself

Thats very helpful and insightful! Some rather impressive results.
Would you happen to have the measurement files for the T34B to import into VituixCad?
Also, do you have the cad file for that waveguide you used?

Yes, I can forward you RAW txt files that can be easily read within VituixCAD, but remember they do include diffraction of the enclosure I built.
