• As a general rule, bass
response increases as a
subwoofer is placed closer
to a wall. Therefore, bass
output is maximized when
the subwoofer is placed in
a corner.

Low-frequency sounds are
normally omnidirectional,
meaning the listener can’t tell
where they are generated from.
However, frequencies between
75Hz – 150Hz can be localized,
especially at higher volume
levels. Positioning your
subwoofer as recom-mended
will provide the most natural
soundstage and imaging from
your loudspeaker system.

strongly recommends
experimenting with the
positioning of your subwoofer
to obtain the most pleasing
results in your room. One
technique that can help you
find the ideal subwoofer
location is to temporarily place
the subwoofer near the main
listening location. Then move
around the room and determine
where you hear the most
pleasing bass performance.
This would then be the ideal
location for the subwoofer.
