A new horn model

Next Round Is On Me
It’s alive!...looks pretty cool by the way.
If you need to send it to someone for testing...or gve out as a beta product for feedback...:over:
 
Cool for sure. If it was me, my next step would be to "detruncate" the flare corners all the way to the baffle a la the venerable Emilar Bowtie.
 
Yup. That's the idea. (Or, as you would say, one and a half).
😄 Fantastic! Something very alluring about that geometry, I like the combination of curves and straight lines. Will be curious to hear your thoughts on comparative sonic qualities with the KS12024 once you've printed one of these new hybrids!
 
Cool. Nice sounding small horns are needed. Something to pair with the 12" woofer mid driver like the 32. 1" correct?
I was thinking something to pair with a 18" woofer project I am working on and super sizing this to a larger format (1.4 or 2").

I am curious to possibilities of expanding the whole horn in an attempt to lower the xover a bit. Anyway, first things first.

Great work as always!

What do you think are the relative advantages or disadvantages of the horns you've built/modeled with "cells" vs "vanes" vs "open mouth" styles?

Great question. I've been "pondering" about the very same thing. Below are my impressions based on listening to the 3D printed horns.

1) Multicellular horns do everything well. Very polite and competent. Have the widest beaming.
2) Multi-vanes. Due to the physical fact that the vanes connect the top and the bottom of the horn walls, they are more much more rigid than the open mouths. IMHO, they come closest to the classic WE horns sound. I prefer such designs.
3) Open mouths. Even with 3D printed horns, they have a small amount of "ringing" possibly due to the lack of internal bracings of the multicellular or multi-vanes designs.
4) 90 degree bends are wicked. They do add a nice and interesting "flavor" to the sounds trading off efficiencies and some loss of the higher frequencies for 3D printed horns. Do not know the effects if different horn materials are used such as cast aluminum or concrete.
5) IMHO, different horn designs produce different sounds. But, a horn by itself does not make a system. The key is to understand the horn characteristics well enough to pair with a suitable woofer to make a system.

To be clear, these are my personal opinions. Do not take them as facts.

Is that approximately the same dimensions (baffle opening) as a 32C horn? If so, I'd be happy to test drive 'em for you with 808-8B's in my Altec 753a clones. ;)
 
a larger format (1.4 or 2").
Other than the PWK1506 for my Axi2050's, not thinking about 1.4" or 2" horns for now. Still modeling and learning from the WE horns by updating the older 0.76" to 1" drivers.

Yes, the baffle opening and mounting holes were measured off my humpy dumpty 32C horn. Should be really close.

Thanks for offering to test drive. To make it a "fair" test, we'll have to add my "32D" horn to the mix. Based on my one "expert tester" the 3D printed 32D still has a bit of "ring" albeit much less than the metal 32's. Still have to modify my 32 design some to minimize the ringing.

Have you turned the 808 8b into 808 8g by getting the aluminium diaphragms and swapping the loading cap for felt? It improved the hf a lot for me
