I would dearly love to see these measurements since your claim does test my credibility. But testing at 15° increments only up to 45° is only a very approximate test. To me the data should be at least 7.5° increments and cover the range +- 90°. If these measurements are as you claim then this would truely be a breakthrough as I have never, in more than 30 years, seen such good performance from a midrange horn.
