My tweeters have a nominal diameter of 37mm (1.5") and a corresponding beaming frequency of ~4.7kHz. I am presuming then that frequencies above 4.7kHz may be subject to the effects of beaming. If this is the correct understanding, what can I do with my tweeter install to limit/control beaming effects? I apologize if I missed any of that discussion here. I looked but did not ascertain anything applicable.
