Some speakers need it like the Charios I still have but don't use. They sounded best with the speakers converging just in front of the listening position and far apart. The owner's manual even showed that configuration. My current JBLs sound great with just a little toe in.
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.
