"minimise the first order reflections and create a symmetric listening environment."
I agree. But James Romeyn, co-designer of new Audiokinesis speakers, has suggested one should try a bit of offset from full symmetry, like 1.5 inch (moving the whole "axis" of the system a bit towards one of the side walls). My room is a bit asymmetrical anyway, so it may not be needed in my case. He also suggested my sub (which I have to place close to the wall) would sound best with 90 degrees phase, which turned out to be right.
