The Stereo Triangle

If the loudspeaker is going to be used for stereo ap-
plications, the optimum listening position should be at
the top of an imaginary equilateral triangle with the two
loudspeakers should be placed at the other two points
of this triangle.
The loudspeakers should be aligned with the listener's
position.

Surround Placement

Speaker positioning for multi-channel stereo purposes
is ideally based on a circle with speakers placed at 0°
(Center), 30° (Front Right), 110° (Rear Right), 250°
(Rear Left), 330° (Front Left), with the listener being
the circle's center (Radius between 0.7-2.0 m). This ITU
recommended configuration may vary depending on the
purpose of the control room (music or film). However,
it is recommended to create a symmetrical listening
position with the front side and surround speaker
pointing to the listener's ear.
The distance to the surrounding walls should be at least
40 cm to avoid early reflections, which can degrade the
sound.
