Finnaly, to do reverse engineering, an additional small segments (as highlighted) will be added and that will increase a little the path length. For sure it's is too small to make difference on the output.
If you add rounded deflector you could reach the perfect shape, if the reflector is flat, it will reduce the error if you not overpass the limit to reduce horn path.
That's it.

An externally hosted image should be here but it was not working when we last tested it.
ooops.
Correcting reverse engineering image. I need to slow down to avoid errors 😀 😀 😀
DONE !!!!!!

I think you've got it. 🙂
Hi LORDSANSUI,
Looking at your Post #18 'Advanced centerline?':
Points a and b are midpoints between 1-2 and 2-3. Points I, II, III and IV are midpoints in the lines from 0 to 1, etc. The midpoint line from I to IV gives you the length around the corner (in this case 90°). Soho54 developed this method in conjunction with actual builds and measurements. In other words the length arrived at by this method gave the same results in his simulations that he had measured, and vice versa.
For tapped horns corner reflectors are stiffeners, and should generally be minimized as they do not improve response, and may cost a little output level. Anything you do near the throat will have a greater effect than the same action around the mouth. A good use of corner reflectors is for mounting wheels or grips. Don't worry about the exact size and angle of a corner reflector in a tapped horn, just don't create any restrictions.
There may be special cases where the reflector actually helps; Tom Danley: "...measurements trump simultions...".
You can get pretty close on paper, but finally you'll have to build something, and measure it.
Regards,

Hi Oliver,
Thanks to check the information. Soho54 method is easier them Xoc1 one and can be easier implemented.
The idea is to build the cab once I need a new one to replace my current Electro Voice T18 clone that is outdated.
Take a look at the final result. Next I will prepare a specific thread to talk about this SS15 tunning for the drive a chosen.
