Final Notes:
Very smooth well behaved coverage pattern from this horn. Horizontal directivity is very even over most of the usable range with only slight narrowing as frequencies rise (or perhaps widening as the fall) while the vertical narrows a bit more rapidly as frequencies increase. Decent match to Faital Pro's published polars but I would say the coverage angles are slightly narrower then what they give using the same average between 2-16khz they spec.
