The table provides the maximum (110°) dimensions only, since all of the 90° dimensions will have zero
distance offset from the listener’s ears.
Rear Speakers (7.1 channel systems)
The rear channel speakers work with the surround speakers to provide a more uniform and diffuse
surround sound experience. In source material that effectively utilizes the rear channels, movement
effects have a more defined path, particularly with overhead effects. Because the rear speakers spread
the surround soundstage out around the listeners, the addition of rear speakers will create a more
realistic environmental presentation. It should be noted that rear speakers are more effective in larger
spaces where they can be placed 6 or more feet behind the primary listening position.
Rear speakers should be mounted at the same height as the surround speakers, be toed in towards the
primary listening position, and mounted between 135° and 150° relative to the plane formed between
the center of the screen and the primary listening position. The table below lists the distance between
the primary listening position and the center of each rear speaker (DR2).
