Speaker Placement

Where To Place The Loudspeakers

A basic question is "where should I place my loudspeakers in the room?" Here are some
pointers for you.
A. Smooth Response: Place the loudspeakers where their frequency response will be the
smoothest and most uniform. The best locations are fairly close to a wall (no more than
about 10 inches from the wall), or out in the room and positioned on ear-height loudspeak-
er stands. Figure 4 and Figure 5 show options for both stereo and surround setups.

Boundary surfaces create reflections from the loudspeakers that will, to some extent, inter-
fere with the direct sound from the loudspeaker to the listener, and these will cause peaks
and dips in response, primarily in the mid-bass range and lower (roughly 250 Hz and lower).
When the loudspeakers are placed within about 10 inches of the wall, the reflected sound
at mid and low frequencies will be largely in phase, or in step, with the direct sound from
the loudspeakers, and interferences will be reduced.
