Thanks....yes, I'm trying hard to ensure smooth transition. Proof yet in the pudding.
Well, finally got back on the tools this weekend to complete the second horn.
Have stained the horns in a Cabolts walnut, with gloss.
Quite a hard job sanding and preparing. If I do another pair, I'd stain prior to final assembly.
Still don't have my new amp, but initial presentation from the horns is OUTSTANDING...I'm very happy. Plenty of detail and superb sound stage. No metal ringing like Altec 511 horn.
I chickened out and did not fit the fins to the horn throat...reading that sound stage depth can be improved without fins....like TAD and Fostex horns.
New six channel amp to arrive soon.....can't wait.

bumping this thread.
has anyone got a simplified cutting plan for these horns? i've tried to make a 3d model usng the PDF's available but i'm not convinced the curvatures are correct. i gave up with the fins so just put some in for aesthetic merit.

An externally hosted image should be here but it was not working when we last tested it.
not sure its that important
and even if you had a 100% accurate model, you might not be able to copy it 100% anyway
removing the fins may change that area a small bit
My CAD 'cutting plan' only used four for one horn section (bottom), consisting x3 24mm layers and x1 18mm layer.
Subsequent horns I intend on building I'll use a calculation to create an accurate profile enabling a true 3D shape by using a 2D router....then it's only a question of sanding to finish off....too easy.

Hi, yes...though that would be a commercial matter...which would need to go offline.
The current build project is for my own personal set-up.
Kind regards.
What a job it was just moving it 100 miles. 4008 pounds of steel. I like that phase plug. I wonder if that is hollowed out? I looked for a bigger lathe, but this was all I could find in my price range. However, if I could find the original bed extention for it, I could turn a 64 foot long ships mast!!!!!!
Maybe 45-50 hz.
Would be over the top though, and very difficult for room placement...for correct flair it would need to be very long.
Why not aim for mouth diameter around 43 inches (110cm). This would slightly larger than AG Trio mid bass.
Then, what materials to use...!? CNC'd layers of MDF rings?
One of my all time fave pics is the jeff Jackson 90cm horn in mahogany laminated pieces.
