((((I was wondering how you have positioned your ProAcs?))
With almost a square room why not try an asymmetrical approach.
This is where you sit in almost the back corner and stare straight ahead into the front corner than each speaker goes up each wall 6 feet maybe 7 or so adjust speakers so you can see just a little of the inside wall of each Proac.
Bring speakers out into the room or push back to taste.
