The hard dome says "When I'm surrounded by a waveguide, I am smooth and can control my directivity"
Reference:
SB26CDC in custom 6" WG by @augerpro
The ribbon tweeter says:
"Really? I don't need a waveguide to be smooth or to control directivity. And I can be heard from all around"
Reference: Fountek Neo CD3.0 datasheet
The compression drivers says "Well I may not be as smooth, or play as widely as you two, but I'm far more dynamic"
Reference:
Tymphany DFM-2335R00-08 in SB Audience H225 90°H x 70°V constant directivity horn.
The soft dome says "Well I may be a bit rough around the edges, and I'm not as sensitive, but people have accepted me just the way I am"

I want to know what happens next.. i.e., which of these does the guy with the ears prefer the most.. 😀
By the way, there are compression drivers which are pretty smooth too.. 😉
Here is the Peerless DFM 2544R on an ST260KVAR waveguide (I think this one was just a 4.5ish ms gated measurement with no additional smoothing)

I mostly grew up with various cinema arrays of the horn systems in my avatar, so pretty much preordained. 😉
Must be a very very small one because
off Axis usually aint very good for large ribbons.
But directivity is not all its cracked up to be.
Because clarity and detail is usually very
good with even cheap ribbons.
And second one down would be Metal Dome.
Steep filters is more the game.
Many systems with " horrible"
off axis. Sound very nice in the real world.
Its nice to see directivity in graphs.
Real world, just clean and detail
no fatigue or least as possible.
Ribbon or metal dome for me.
Live sound your pretty much stuck with
a horn. And found larger horns
tend to sound better, but on paper usually
dont " look" great.
And the crossover makes most the difference
as far as when they squak or dont squak as fast
at high SPL

Despite their slightly higher distortion than domes, when ribbons are used in their intended passband, eg. 4KHz and up, they tend to exhibit very controlled off axis responses:
One has to wonder whether this is why may be favored to domes...
