I try to be extremely concise for the guy who thinks that Seas is making horns.
It turns out Celestion designed 2 horns for the Axi2050.
The stack of horns are 90° x 45° and on top of the booth, visible on the first image below, is another with 60° x 40° coverage.
The latter horn was posted earlier (and again below).
At the time I thought this could be a K-Horn, but I don't think this is the case.

...All Waveguides are Horns...
I won’t bother you with words like « polysemy » or « terminology » because the culture often encounter the Parkinson's law. Parkinson's law - Wikipedia
The linguistic subtilitie had been invented in order to differentiate things, a Horn is a hollow conical object and a WG is an equipement designed to diffract and refract the acoustics waves.
I’m a bit wet behind the ears
But is this a one mans obsession ( marketing campaign)
For Pete’s sake the driver is unobtainableit’s a ghost driver
It has been said several times in this thread that it is an OEM only component.
That means it'll be perfectly obtainable, if you're a commercial manufacturer who'll be ordering by the hundred (or more).
A handful at least have already made their way into the wild.
The only weird thing is that so many people outside of the target market are showing so much interest.
(That's us, by the way.)

Perhaps less spectacular than the Axi2050, but at least readily available, even though Celestion states "OEM Only".
"The CDX14-3040’s diaphragm surround has a periodic geometry, which effectively eliminates circumferential modes while still allowing for linear excursion. A high-temperature polymer clamp ring is optimized for stiffness through its geometry, ensuring that the dome is always held rigid and preventing the diaphragm from bending. The diaphragm assembly is located into the magnet with a precision-cut aluminium locating ring. This is probably one of the most important parts of the driver, but so often overlooked. The locating ring ensures the coil is always held concentric to the magnet gap, as any offset of the can allow it to hit the magnet assembly. Between the cover and the clamp ring is a semi-rigid layer of a polymer similar to rubber, which spreads clamping pressure more evenly across the diaphragm assembly. This means that the diaphragm assembly is more likely to stay flat, holding the dome without allowing it to deform.
Inside the die-cast aluminium cover, acoustic damping material absorbs much of the vibration to the rear of the dome and makes the sound into behave as if the cavity is slightly bigger than it is. This enables the device to work down to a lower frequency, as the air load behind the diaphragm is often a limiting factor."
..."The CDX14-3040’s diaphragm surround has a periodic geometry".
I call these things radial ribs, but I might be missing something here.
For a hard suspension Titanium diaphragm, the breakup seems well behaved.
Evidently these are manufactures plots, but they look better than those of every other Celestion 3" diaphragm driver.
It's clean to about 13kHz and the impedance peaks are unusually low/smooth.

Yup. I'm thinking it has a 46mm voicecoil for the highs and a 64mm voicecoil for the mids. 464. We'll see.
To keep things shorter, we used inches for the mid diaphragm and millimeters for the HF. So it's a 4" (100mm) coil midrange and a 2.5" (64mm) coil HF. A hybrid name for a hybrid driver!
Here's a new thread to discuss it in: B&C DCX464
