PLAciNg thE SUBWOOfER
The performance of a subwoofer is directly related to its placement
in the listening room and its physical position relative to the other
speakers in the system.
While it is true that in general our ears do not hear directional sounds
at the low frequencies where subwoofers operate, when installing
a subwoofer within the limited confines of a room, the reflections,
standing waves and absorptions generated within the room will strongly
influence the performance of any subwoofer system. As a result, the
specific location of the subwoofer in the room does become important
to the amount and quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will increase
the amount of bass in the room; placing it in a corner (1) generally will
maximize the amount of bass in the room. However, corner placement
can also increase the destructive effect of standing waves on bass
performance. This effect can vary depending on the listening position –
some listening positions may yield very good results while others may
have far too much (or too little) bass at certain frequencies.
In many rooms, placing the subwoofer along the same plane as the
left and right speakers (2) can produce the best integration between
the sound of the subwoofer and that of the left and right speakers. In
some rooms, the best performance could even result from placing the
subwoofer behind the listening position (3).
We strongly recommend that you experiment with placement before
choosing a nal location for your subwoofer. One way you can determine
the best location for the subwoofer is by temporarily placing it in the listening
position and playing music with strong bass content. Move around to various
locations in the room while the system is playing (putting your ears where the
subwoofer would be placed), and listen until you nd the location where the
bass performance is best. Place the subwoofer in that location.
