About the virtual speakers in FOA for stereo. And the ideal listening angle is real life os +- 23 degrees The best way to listen to stereo loudspeakers is not with totally linear speakers :-) There need to be some modfication to direct sound from the speakers if the sound to the ears is to be the when listening to a centered sound as when listening to a mono sound source in the centerr. This is called the stereo sytem error.
