1) Beautiful speakers, I am jealous
2) did you buy it with the stands?
3) I think with the tight space, you will need to raise them higher (on a stand) and move them forward and closer to each other, under 1.8m. That's where I would start, then I would move them back towards the wall, further apart, see where it works, find a track with know imaging and expect that in front of the TV.
4) I have similar monitors and they sound best, on the floor, but I have nothing for 2 meters before the furniture. I wonder if that would work for you, I suspect the opposite, but worth a try
