I found it in the sticky thread showing off systems.
I've been a little obsessed lately. I literally fall asleep thinking of horn shapes.l

A horn profile is dictated by what you want the horn to accomplish. Has nothing to do with the appearence or visual impact.

It is interesting that you associated Metronome with ConeHead, the name of a pre-cursor to the met was conehead...

Its not art, its math/physics, Every bend is a loss which has to be calculated for and made up for expansion ,length and area of the wave front. Its also a timing aspect. The less bends, the less distortion and the less loss of efficency.

Greetings Ron, given that multiple folds require more compensation, would the BiB's single fold make it therefore very appealing? Or should the BiB's simplistic taper be adjusted, maybe with a Frugel-Horn style wedgie or other shape adjustment?
Any thoughts very kindly appreciated.

Well, every horn doesn't look the same as so well demonstrated here so there are various roads to Rome...
Decisions on the configuration are often based on appearance, space available, materials, tools, SAF, drivers available. but of course the bends and folds and flares, etc. need calculating. I don't think there will be argument there...

Hmm, the number of bends doesn't affect a horn's gain BW, distortion, etc. per se, it's the quality of each bend and the mouth termination, i.e. the wider its BW the larger each bend and the mouth termination must be to minimize refraction/reflection through the bend(s) and friction loss over distance.
WRT the BIB and folded pipe/BL horns in general, their crude bends are pretty much the antithesis of what's required for maximizing HF gain BW, which usually is a plus in that it helps damp the unwanted BW that causes audible comb filtering with the driver's output.
For instance, this 1" throat exit compression driven horn has a ~10 kHz usable BW once EQ'd ~flat, Pretty impressive considering its size required to also load down to ~50 Hz.........:

Wow, that's a fascinating horn. Quite a bit more bendy than the BiB. I keep wondering what would be the BiB 2.0?
Or to put it another way, what would be the smallest additional tweak to the BiB that would yield the greatest improvement? Or is it already fully evolved, all things considered?

Make it as visually pleaseing as possible.
I'm not kidding you, this will make an improvement to the way you experience the music.
As for 2.0 take a look at the frugal horns project.
Kaan and GM: Gotcha and thank you -- I guess there's nothing in between BiB and BLH.
Don Bunce: Beautiful.
GM: Wow, how does one turn metal into those bendy horns?! Are they cast metal, or hammered, or turned on a lathe? Thank you in advance!

Cool site, thanks! FWIW, the $12 1922 King Am-Pli-Tone would be ~$138 in 2007, so reasonably priced for a formed metal horn.

The initial expansion is a flanged pipe that transitions to a welded up sheet metal construction bolted to high density wood construction final sections. Here's the two being cloned using the original metal HF sections:

I imagine if you have to ask the delivered price you probably can't afford them.

Thanks for putting up that club shot again.
Those horns are what keeps the hobby interesting.
That and whatever Bill Fitzmaurice is up to.
