Beautiful work, I love the simplicity...
I will be following this very closely 🙂
I understand beauty is in the eye of beholder, but these remind mr of

Those radiators look fab too 😉
Also as this is an open baffle speaker thread... these speakers are open baffle... 😉

Curved open baffle
Bothered me not using a pair of BG Neo 10 planars for a long while.
I was never happy with them in a tuned box with a 4" wide port behind them, for back output, or on a flat baffle.
So now I'm trying them open backed, front firing into a horn, which starts out just as wide as the membrane, quickly narrows to 2", then flares to 19 1/2" wide by 11 1/2" high, in a 13" run.
As hoped, it fills things out nicely from 350 hertz up.
I guess they're pretty good tonally, as they're a near twin of some old Peerless 6 1/2 " dual driver cabinets, old ones made in Denmark.
Slightly higher output, better ambience retrieval, and no box resonances on vocals.
Horn sides are a cheat, 3/32" Baltic Birch, no bracing, as I hoped this would add some resonant output to the driver sound.
Nothing to measure this with, if it does help.
Anyways, for me, this was a worthwhile start to another project.

I think this was a great start!
I have only built waveguides so far with the purpose of getting a couple of dBs in the low end.
That is, not that long throat.
It would really be great if you can do some measurements...

Have you listened to them from the backside?
I have been experimenting with a similar (Neo 8), and it sounded and measured better from the back side...

That is exactly what I am planning to do with a couple of 50x15 cm electrostatic panels. Open back? I tried that with a midbass horn for the Fane S 8M and I preferred a back chamber with lots of damping material. But those were meant to be played from 120-600Hz. Maybe I should remove the back chamber of all my compression drivers. 😛
Sorry, it was Neo3. After much searching and self question, I found the ugly behemoths at the attic!
The horns made them go down to 600 Hz, with wonderful soundstage and crisp treble, if listening from the driver side.
From the horn side they sounded like crap....
I took the front magnet assy off for better sound and to match sensitivity of the two parallelled Peerless SLS12 dipole woofers.

Wow, so you just drilled the rivots out and removed the front magnet array? Then you listen from the planar side and the horn faces to the rear?
No, I enjoy the look of horns, and wish to keep back dispersion narrower than front
For the purpose of simpler front wall reflection damping, at mid and treble frequencies.
Pretty happy with this, I need to make tweeter integrate better, aso well as trying a push pull slot loaded bass array, with a similar flared baffle.
Let me know how your electrostatics go, I'm considering trying out some kits from acorn audio.
