For me as DIY it's even easyer use straight-edged tube, is even more aesthetic IMHO due to easyer sanding.

And I see I'm not the only fool who wants pair a 4367 WaveGuide with large format CD.
Guys run the large format drivers on pretty much any horn they'll fit on. Plenty of guys run them on the M2, I run them on the H4338 that was originally used with a 435AL, Giskard had 476Be on a 1400 Array horn I think at one point.

I think the question I have is why JBL didn't - other than cost, of course. And I imagine they used that dual ring radiator on the 4367 since it's a 2-way, but the 4" stuff ain't bad 2-way with coated Ti phragms, I'm running 2-way during the summer on mine and it sounds fine, better than fine.
