the weirdly asymmetric cone morphology of that midrange/treble thingy is makin' my brain hurt.
Maybe the cone material was cut according to the Mercator projection, I dunno.

Yes, but the material making up the cone in the image you linked is not so bizarrely sectioned as is the one in the "Arcturus 3"

And, no not everyone is using it. That would be hyperbole.
It's just a new flagship in their line up, -3dB at 28Hz is quite impressive for a closed box. Sharp edges and external amp/dsp suggest flush mounting, they would loose a lot of appeal when used normally, as there's nothing in the design to fight SBIR and side diffraction from enclosure edges.Hi
I stand to be informed, educated, astonished or ...
What is special particular about this speaker? The claim that they use DSP to flatten .. everything? Perfect impulse response? What is so special about this speaker? or about about, several of the speakers you start thread about?
Peace.
to have this kind of phase response in the low end with such sharp cut off they probably used linear phase filters. Impulse response shows significant pre-ringing, I never use it with low end as it's very easy to hear, wonder if it would be noticeable in them at least for someone who knows what to listen for
Erin reviewed the smaller Pulsar which yielded the ff. step response:

The low end might not exactly audibly "pre-ring"...
@KSTR briefly had this to say across at DIYAudio:
"... this appears to be a speaker where the natural phase response from the woofer highpass was corrected to linear phase which creates the point-symmetric step response.
That's a neat trick for speakers to have "fast bass" down low. The price you pay is that some signals (like certain kick drum sounds) may be rendered with audible artifacts. The rising slope in the time-domain is not ringing and does not sound like ringing, rather it sounds like pink noise pulse ramping up (very interesting acoustical illusion)."
This speaker has one of the lowest intermodulation tone distortions even lower than KEF highest classes. Therefore it should sound very "clean".Erin reviewed the smaller Pulsar which yielded the ff. step response:

keep in mind the ex machina is using a 8'' woofer, also erin was talking about these spikes being measurements error, there is no reference IMD, erin sadly forgot that very important measurementThis speaker has one of the lowest intermodulation tone distortions even lower than KEF highest classes.
