Great article w/ excellent photos.
Nice.......
Wish I had the time (and expertise) to build something like that, but I'm from the metal
fab side of the road. About 15 years ago I did build a set of short throw exponential horns
for my 288's. I'll see if I can find a photo...... but they came out pretty good - from a visual standpoint anyway. 100 % tig-welded w/ all the welds ground down and polished. They sounded.......o.k. from what I remember. Never got around to mounting them in a cabinet or dampening them in any way (and they needed to be....) and ended up trading them for something.
Wow, very cool !!

Is the multicell for bracing mostly, or sound direction? What if a person just made the same size horn, without all the braces that turn it into a multicell, would it still work?
Dave
It's for ~controlled directivity to a very high cut-off, i.e. the original ~constant directivity horn design, ergo if just the 'shell' followed the outer flares it would be a 'plain Jane' rising on axis expo mid-horn that due to excessive beaming and internal reflections would need to be limited to around a decade of useful BW at most.
BTW, they aren't 'braces', but individual high frequency horns of very narrow directivity tied together to get a lower cut-off due to a much larger mouth area.
