Help with Ten Pi Horn for 12" Coaxial


Any help here would be greatly appreciated.

I would like to construct something similar to the Ten Pi for a 12" coaxial driver with an Fs of 47. I have tried Onken Petites and TQWT's with the results leaving much desired.

Has anyone built something like this. Any plans, dimensions, and or reference material would be very much appreciated.

Thank you.
