HiFiCompass I really appreciate what you're doing, and you're doing an excellent job of it!
I missed Zaph's website for quite a while, and found your site via his recommendation.
Cheers to discovering more gems. The MW19TX is a diamond for sure.

Seems odd that SB has the MW16TX-4 as higher sensitivity than the paper version, but HFC's results are the opposite?
19cm version is also more sensitive according to SB, but only a bit and in HFC's results are basically a wash. That's good, I had a 3-way in mind and didn't want to spend the money on the TX version for the woofer if there wasn't a benefit.

I have an interesting question. Now that we have proper Beryllium and Diamond tweeters, does perusing plasma or using plasma makes sense - cost aside. ?
The review of the Satori TW29BNWG-4 beryllium dome tweeter with a waveguide:

Many thanks, nice info on the BNWG -
This is Used in Jeff Bagby's last and self proclaimed best speaker, the Helios, the write up on the facebook site uses a prototype that was then put into production as this model iirc -

It looks good but at this price point i would expect more, i have this feeling that sb acoustics is rather sloppy, why do not they fix obvious flaws?
Once again, thanks for the review 🙂
This driver certainly is very (too ?) expensive.
But what obvious flaws do you see about it ? The 16 khz dip ? That would be a consequence of the waveguide's throat width. Not something you can easily correct unless you use a smaller tweeter. Maybe you are thinking about something else ?

I would like to know too, what is so wrong with TW29BNWG-4? I think, they pulled out the maximum of possible from mating a stock tweeter with a waveguide. If it was a design from scratch, they could achieve much better performance. But who needs it?

I recall my results of TW29DN and Jantzen WG, there was no dip (actually it is more like diffraction) around 17kHz, and I always wonder if TW29BN would work well in that WG too. Definitely worth trying before bying this BNWG.
Jantzen WG has very different profile compared to BNWG.

The fabric dome behaves quite differently in the top octave compared to the beryllium dome, so the difference may be not only due to the waveguide shape

The WG design has an influence of course. But, IMO, the main cause for the absence of the 17Khz dip in the TW29DN case probably comes from its more directive off axis response compared to the beryllium version (earlier break-up of the soft diaphragm). According to Hificompass test, the former has a deep null right 60° off axis where the beryllium is narrowing, but not as much. Ring radiator tweeters are even narrower than soft dome.
TW29DN soft dome FR above, TW29BN beryllium below. Because of its narrower directivity above 10khz, the soft dome version probably does not interact as much with the waveguide throat, which would explain the absence of the dip in your case.

All good points and I am well aware of them. I just mentioned that jantzen plus bn combo could work well. It is very easy to mount tw29 on jantzen wg.
Thank you for reviewing this unit, very interesting. Looks like this unit would not be an alternative to ATC. Not too different though...

Not close to ATC. If it had a more normal rear chamber, it would be very comparable to the Morel offerings with a bit more extended high end response, not sure that extended high end is super important for midrange use. As it is, the small tube chamber still throws me for a loop, so I would tend to lean towards Morel dome mids as my choice preference.
MD60N-6 is most comparable to the Dayton RS52 I think. Once you make the response flat the distortion below perhaps 700-800Hz is going to become unacceptable at high volume levels. It only looks OK there in the HD measurements because it's naturally heavily rolled off.
The only dome I've seen which can go low like the ATC is the Tang Band 75-1558SE and perhaps Morel MDM75. All of these are now relics of history so I'd give up on the idea of having a dome go lower than 700-800Hz at high volumes.
The Morels aren't nearly as good performers in non-linear distortion as any of the aforementioned drivers. Their frequency response is much easier to work with but personally I'd take the driver with better HD and a rougher frequency response. You can hammer a rough frequency response into shape but you can't remedy subpar non-linear performance.
One dome that I haven't seen tested but am somewhat hopeful for is the HiVi DMN-A, not to be confused with the DMB-A which is nothing to write home about and very Morel-ish in its performance.
