Wish to read more about this speaker, their product page is so poor that only provides 3d rendering.
Does the manufacture provide any measurement at all?
They look like they'd be acceptable in terms of decor to ' non audiophile/enthusiasts , partners '
Here is a test with background of Gradient http://highfidelity.pl/@main-843&lang=en
Another on ewith measurements https://www.lowbeats.de/test-gradient-1-4-ungewoehnliche-koax-standbox-im-kegel-design/
I wonder if the 10kHz and 16kHz nulls are room effects because another in-room measurement I found doesn't show it:
That's better performance than the Revolution's coax, which still has a 16kHz null.
A 3-way speaker can be onni, mono, cardioid and dipole at different frequency ranges, and that's what 1.4 does. But I haven't seen 360 deg polar measurements of it.
I have done a clone of it two years ago for one of my daughers. My midrange ball's rear vent is smaller. Active with Hypex FA123 plate amps. My crossovers are acoustic LR2 at 300 and 3000Hz. Same SEAS MR18 midrange, but alu tweeter and 10" SB bass in closed box.

Great measurements, but it really does look like a Dalek, though.A 3-way speaker can be onni, mono, cardioid and dipole at different frequency ranges, and that's what 1.4 does. But I haven't seen 360 deg polar measurements of it.
