DEPRECATED - 90x60 degree horn - elliptical profile with wide radius - 2 bolt 1" compression drivers

This is an elliptical horn/waveguide with 90x60 degree coverage angle, very roughly based on the Sica SSH-1 design on clearance at https://www.amplifiedparts.com/products/horn-sica-1-compression-elliptic.

I chose this design both because of the elliptical prof
