@soix All point source speakers are relatively poor off axis as the volume the speaker produces drops off rapidly with distance including the Ohms. The best kind of speaker for off axis listening is a line source. Because the volume drops of much slower with distance you can still hear the far speaker clearly. A full range line source has to run from floor to ceiling, anything shorter becomes a point source at low frequencies. As an example Magnepans become point sources at about 200 Hz. Above that they are line source and clearly audible off axis. The only full range line sources I am aware of are the 8 and 9 foot Sound Labs ESLs.
