Speaker Placement and Listening Position
Most video editing suites use near-field monitors, which are speakers designed to be
listened to at fairly close range. Speakers should be at least a foot or two away from
any walls to prevent early reflections of sound, which combine with and muddy the
original sound.
Position the speakers as far from your listening position as they are from each other
(forming an equilateral triangle). For example, if the distance between the speakers is
6 feet, you should place yourself 6 feet from each speaker. The apparent width of the
sound stage, or stereo image, increases as the distance between the speakers increases.
However, if the two speakers get too far apart, sound information appearing in the
center (between both speakers) starts to disappear.
