I've tried mine in three positions.
1. Directly on my left at the side of the sofa firing towards the screen
2. Right next to the front right speaker firing towards the listening position.
3. In the far corner of the room, to the right on the listening position under a coffee table.
For practical reasons it's staying in position three. However, position one, next to the front right speaker sounds far the best. It seems to blend the sound in much better. Position 2 not good at all as you're just to close to the source of the bass. Position 3 is a good all round compromise...
