Placement
• 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.
• It is also recommended
that the subwoofer be
positioned along the
same wall as the front
loudspeakers.
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 recommended will provide
the most natural soundstage
and imaging from your loud-
speaker system.
Remember that these are just
guidelines. Since every listen-
ing room is different, JBL
strongly recommends experi-
menting 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 tem-
porarily place the subwoofer
near the main listening loca-
tion. 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.
When we designed the
PSW-D110 powered subwoofer,
our goal was to offer the user
the best possible performance
combined with the the
most flexible and complete
installation options. Please
look over the following three
examples to determine which
description best matches your
system and follow the corre-
sponding hookup instructions.
1) If your receiver/amplifier
has no subwoofer
outputs or preamp
outputs for the left
and right channels.
