• Unplug the subwoofer power cord
from the electrical outlet if it will not
be used for a long time.
• Only connect this unit to a power
supply of the type described in the
owner’s manual or marked on the
unit.
• Route the power-supply cord so it is
not likely to be walked on or pinched
by items placed upon or against it,
especially at the plug, the outlet, and
the point where the cord exits the
unit.
Placing the subwoofer on the same stand
or shelf as your turntable can result in a
low-frequency rumble or acoustic
feedback.
Cautions:
• To prevent fire or shock, do not
expose this subwoofer to rain or
moisture.
• Do not place the subwoofer with its
metal plate against the floor.
• Place the subwoofer away from heat
sources such as radiators, stoves, or
other appliances that produce heat.

Cautions:
• To prevent the cabinet from warping
or discoloring, do not place the
subwoofer in a place where it is
exposed to direct sunlight or excessive
humidity.
• Do not place the subwoofer where it
might be knocked over or exposed to
falling objects.
• The metal control panel on the back
of the subwoofer acts as the heat sink
for the subwoofer’s internal amplifier.
Therefore, place the unit at least 4
inches (10 cm) away from a wall, and
do not let anything come into contact
with this panel.
Where and how you position your
subwoofer greatly affects its bass response.
Adjusting the subwoofer’s volume control
in relation to the left and right speakers
and adjusting the subwoofer’s high cut
filter also affects your speakers’ overall
sound.
Although low frequencies are non-
directional, factors such as room
reflections, standing waves, resonance,
and absorption strongly affect your
subwoofer’s performance. For maximum
bass output, place your subwoofer in a
corner. To reduce output, move it away
from corners and back walls. Even slightly
moving the subwoofer can have a major
effect on bass response.
We recommend that you test the
subwoofer in different locations to
determine where the best balance is
between your satellite speakers (if used)
and subwoofer. We also recommend that
you place the subwoofer at least 4 inches
away from the wall, and at least 2–3 feet
away from your television or computer’s
disk drive system so the subwoofer’s
magnet will not distort the colors of your
TV picture or erase your floppy disks.
