IF you do most of your listening off-axis, as I do, you might want to try more aggressive toe-in. Because of the extreme toe-in, the closer speaker is firing away from you more, while the farther is more directly aimed at you in the off-axis spot.
I discovered this as a side benefit- someone in another forum suggested that my Spatial Audio M3 Turbo S speakers might sound better with extreme toe-in. They did sound better to me at the sweet spot, but also much improved off-axis.
It’s worth a try if the majority of your listening is not in the sweet spot.
