Well, I have a theory that the rough surface may be helping to attenuate multiple back-forth axial reflections, but from what you say, it may be that it results in - what's the proper term? - irregular as opposed to laminar flow at the surface. Reynolds number in pipes, all that sort of stuff. Not sure how that would help sound, but again, I think it may help limit *radial* reflections. Which, incidentally, is one reason why all front loaded Lowthers I've heard have a "disconnected" treble to my ears - complete mismatch of whizzer (itself a yucky idea) to the horn throat.

Ah, *turbulent* flow, that's it. I can imagine the vortices at the horn surface attenuating reflections. But then it's entirely possible I'm talking out of my rear chamber.

As for Cogent, they were using DEQX, but I believe they are now considering going for a more purist approach. I think, as you imply, you're just going to have to try and listen to them, although on paper, they certainly have many fine ingredients.

Fun thread this btw.
cheers
