I'll try and take some measurements outside and use 3 different mics. I'll also mount it in the box (when done) and take some measurements. Unfortunately I don't have any other flares I can test with, but I will measure some other speakers with a published curve (non horn, I have some 7" Stryke fiberglass cone woofers) and see if there is a hump there also. Thanks for the info on all the different variables and I'll try and minimize all of them. --Ryan
