Thanks. I did know what CD horns are. I just don't always understand the jargon of audio. You have to understand that I did know most of the jargon 25 years ago, but then children and college expenses and all kind of things intervened, and I was out of the picture for a long time. My own field is clinical school psychology, not audio or electronics.I am pretty sure what the other poster mean about unequal wave fronts (time delay among speakers?) and I'm pretty sure with a combination of time delay adjustment in the electronic crossovers, and placement in the speaker system, that is a fixed deal. But I'm not sure if that's what he is talking about.
