Non parallel walls cannot create standing waves between them. Most important is the Left and Right wall, each out a few degrees against the centre line. A room in a room construction is perfect for this. Front needs to be perpendicular to the Centre line, the back can be perp as well, but cover with diffusers in that case.
Yet another benefit of a acoustic transparent screen is that you can cover the wall behind the screen with absorbers, which catch all first reflections from that end of the room. Of course only where there are no speakers...
Good integration of audio and video will create the best experience and room design and equipment can only be as good as the weakest link in the chain.
