This is a VERY nice report. I'm still wondering how you aggregated your scoring in order to arrive at the "winners" but that is a small matter as compared to the more detailed information on the various horn/driver approaches and their tradeoffs. I wonder if anything in general can be said about horn design performance based on these measurements?
One disappointment that you explained in your report--not being able to measure the various off-axis responses due to time constraints--is actually a very large performance criterion in how I view different horn designs. Those horn/driver designs that result in a more constant coverage over a controlled polar coordinate region (e.g., 90 degrees horizontal, 45 degrees vertically) would be of great interest even if other trades in performance might be required such as reflections, odd harmonics and higher-order effects vs. more constant coverage performance in vertical and horizontal dimensions.
Can you share your views on this subject?
