[QUOTE="Timber_MG, post: 56737, member: 18"] Average out a few off-axis measurements before you evaluate bumps at the lower end of the FR scale with these. The directivity only settles higher up the frequency spectrum and such bumps are quite possibly diffraction effects or related to the length of the horn. The power response hardly changes, the directivity plot (as a function of horn+baffle) does. What angle were you using? I have done 80, 90 and 100 degrees in the past. [/QUOTE]
