I agree, it's not popular and directivity control, is not the main reason. The reason is the main "quasi audiophile" market is geared toward 2 way speakers with a 6.5 inch woofer if you can call it that.The whole concept of a "mid-tweeter" isn't popular these days. Smaller sizes like 27-29mm with an integrated waveguide are preferred for their better directivity control at the crossover region and above 12kHz.
It gets a boost when put into a waveguide. Besides, the woofer it's paired with and the box volume will mostly determine sensitivity.Sensitivity: 88.5 dB!
Not very efficient nowadays.

Those things absolutely matter if you care about tonal accuracy and neutrality. Maybe you're on the wrong site.there is a condition among DIY speaker builders where they look at SPL of one driver relative to another and at SPL at one frequency relative to SPL at another frequency ....
THOSE THINGS DO NOT MATTER
it is the ABSOLUTE spl that matters - not SPL relative to anything else
That has nothing to do with my listening levels in my house.rock concerts are regulated to 100 db AVERAGE level @ listening position ...
Disagree because there are good examples of implementation out in the wild.3/4 domes are suitable only for nearfield monitors and even then only for the subcompact ones that you have to carry with you on a plane or something
Maybe you didn't use a good one or the implementation was bad.using a 3/4" dome tweeter ( with perfect sound quality ) is one of the biggest regrets in my speaker building life. even though it was my first speaker and i was in high school i will never forgive myself for this.
Here is the renowned Jeff Bagby speaking highly of the SB19.

Someone in that thread pushed it to 110 dB and it didn't fall apart. And that's in free air without a waveguide giving it any advantage.
Of course in the end it's all about the implementation. The best tweeter can be made to perform poorly.
And here is an excellent implementation of it: https://www.audiosciencereview.com/...dt-s400-mkii-spinorama-and-measurements.30251
Again you're wrong. These are being used in speakers that get plenty loud enough for home theater use. Mine have plenty of headroom that I don't use because it's simply not comfortable to listen to them that loud. We really only need max 95 dB for peaks at home with an average level of 75-85 dB.there is definitely a place in the world for 19 mm domes. that place is in micro-sized nearfield studio monitors mated to a 4" woofer.
the tweeter is not going to be the first thing to give out, especially not in a waveguide. The bass driver will give up the ghost way before the tweeter.
How can an 18'' subwoofer reproduce a 2m double bass, a passing truck, a volcanic eruption in a movie with a 4'' VC? Such comparisons usually lead nowhere.please explain how 3/4" cloth-soaked-in-asphalt dome driven by a VC half the size of a wedding ring can reproduce a crash of a 1 foot cymbal ...
No, that is not correct, at least for Germany. It applies 99dB(A) average sound pressure level (at a maximum duration of 2h) at the "loudest point" accessible to the audience (for example, directly 1m in front of the PA speaker).rock concerts are regulated to 100 db AVERAGE level @ listening position ...
The 19mm SB tweeter delivers about 100dB@1m@11V continuous power (at appropriate crossover frequency). The peak sound pressure level will probably be much higher.3/4 domes are suitable only for nearfield monitors and even then only for the subcompact ones that you have to carry with you on a plane or something ...
...
the absolute max SPL of a 3/4" soft dome will be about 100 db PEAK @ listening position.
Do you know of an example speaker using such a crossover? I have one crossed at 2670 and another at 1800 (waveguides).3/4'' (19mm) tweeters are usually crossed >3kHz with -6dB at the crossover frequency.
