I'm not sure I'll helpful it is to know the dispersion qualities of any given speaker unless you see a straw coming out of the speaker rather than a cone.
Horn speakers definitely are dispersed otherwise no clue.
Is toeing speakers a bad idea?
I was toeing in my speakers and that seemed like a good thing to do. But then I decided to de-toe the speakers. I was hoping that the speakers dispersed things well enough and maybe they don't need to be focused so much to create a so-called sweet spot.
I found the imaging in the room was a lot better and sound improved. The room is a rectangular room and the speakers are placed at one end of the room about 3 feet from the wall. Room sizes 17 x 23 with a 7 ceiling. Maybe someone can share some rationale for this. I feel the sound waves may spread out better and not be so disturbed when they collide in a so called sweet spot near my skull.
