His proposal looks like this. Listening position at the wall, and speakers almost in the middle of room.

Practical or not, that was considered optimal.

"Optimal" in terms of what?

I'd think having on-wall or better in-wall speakers with the seat away from the wall is much better in terms of clarity and spaciousness.

I have to agree with you Markus.

The pictures in above paper say that ears should be 0.4-1 m in front of wall. So much for "seeing is believing" .

I also agree. For practical reasons I have my seat against the rear wall. Because there is audible colouration from the rear wall reflection, I put an absorber against the wall. This helps for timbre but unfortunately it really kills spaciousness and makes the sound somewhat dry/less lively.

How are the side walls? I have the thick absorber behind my head, but I feel quite strong spatial effect with bare side walls. Speakers on the long wall with strong toe-in. Speakers have smooth, but wide dispersion (Seas DXT + 6" woofer).

Side walls are at least 2 metres away from the speakers and the have a +-60 degree coverage angle, so that contributes to the lack of spaciousness. But the change in 'dryness' with the absorbers is profound, it may be less so with closer side walls or wider dispersion.

This set-up is not optimal for these speakers, they would do pretty good relatively close to the side walls. But in my room that is not an option.

Just to put the record straight, this is what was recommended - note the minimum distance from the back wall:
