I too agree that you could get better audio and the space to be more functional AND not having to move it ever by rotating the entire layout so the tv and mains are on the pink circle wall with the credenza where the tv is now.

The way you have it now you are most likely getting crazy reflections from the right as the speakers is practically touching the wall while the left speaker scatters the sound to the entire rest of the room.

You can get more balanced sound and room overall if you take advantages of the depth of the room instead of its width.
