I’ve been yapping about angle of dispersion; initial reflections; alternate toe-in for single or two listeners; and importantly for home theater: wide dispersion.
Just created this virtual system to illustrate my beliefs/advice based on many years

btw, viewing anybody’s system, open 1st image: top right corner, ’toggle full screen’ gets rid of the ads and shows image captions, and use side arrows for a slide show.
