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 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 (16") to avoid early reflections, which can degrade the
sound.
