I've found pros and cons in all of the placements.
That's the puzzle, they all sound a bit different in certain areas,not one position for me was the best, so I settled for the Cardas placement for planar speakers and moved my listening seat further away from the speakers so that the 3 angled panels lock in better,so the triangle is far from equal.The speakers fire straight no toe in.
They are 73" from centre of speaker to side walls,58.09" from centre of speaker to wall behind them,95" apart(side of speaker not centre)and 160" to the listening chair.
This also is the most pleasing from a visual perspective.
