Left Rear Height/Right Rear Height speaker pair
We recommend that the Left Rear Height and Right Rear Height speakers should be
mounted on the rear wall (instead of on the ceiling) in line with an approximately 30
degrees horizontal from the center-front reference. If the Left Rear Height and Right
Rear Height speakers must be mounted overhead, they should be placed no more
than one-eighth the distance to the middle of the room, approximately 135 degrees
vertical from the center-front reference. Figures 27 and 28 show the range of angles
at which the Left Rear Height and Right Rear Height speakers may be placed.
