I know you are a 1 seat kind of guy, but we all move around a little. Some of the worst speakers for this are Sanders’s flat ESL designs. No comb filtering issues, since it is a single panel, but the sweet spot is a 1mm cube. Your neck and shoulders hurt after half an hour from holding your head so rigidly in place. :)
So it’s worth listening for a reasonably comfortable listening window.
Best,
