Below are some helpful tips on placement of the Surround Sound speakers.
To avoid wireless interference, keep other wireless equipment 1 – 3 ft. (0.3 – 0.9 m) away from the wireless receivers. Place the speakers and wireless receivers outside and away from metal cabinets, other audio/video components and direct heat sources.
Place the speakers on their rubber feet on a stable and level surface.
Place the speakers at ear height or higher in the back of the room.
If placing the speakers in an enclosed bookcase shelf, position them at the front edge of the shelf.
For a sound that is directed straight at the listener, aim the speakers in towards the listener.
For a sound that reflects off the walls to fill the room, aim the speakers out towards a rear or side wall
