Final Notes:

Large horn so the horizontal pattern control extends below 500hz, unfortunately the dispersion is a bit rough. Surprisingly the vertical coverage pattern is much smoother though there is a small kink in the top octave which is most likely due to a small gap or discontinuity on the horn between the end of the threaded mount and the start of the horn throat.
