Operating Precautions
Placement
• The subwoofer cabinets are made out of wood and are
therefore sensitive to extreme temperatures and
humidity, do not put them in locations subject to direct
sunlight or in humid places, such as near an air condi-
tioner, humidifier, bathroom, or kitchen.

• Do not put water or other liquids close to the speakers.
If liquid is spilled over the speakers, the drive units
may be damaged.
may be damaged.
• Speakers should only be placed on sturdy, flat surfaces
that are free from vibration. Putting them on uneven or
unstable surfaces, where they may fall and cause dam-
age, will affect the sound quality.

cal position only. Do not use it in the horizontal or
tilted position.

• If the unit is used near a turntable, CD player or DVD
player, howling or slipping of sound may occur. To
prevent this, move the unit away from the turntable,
CD player or DVD player otherwise lower the unit’s
output level.

Using Close to a TV or Computer
TVs and computer monitors are magnetically sensitive
devices and as such are likely to suffer discoloration or
picture distortion when conventional speakers are placed
nearby. To prevent this, the speakers feature internal mag-
netic shielding. In some situations, however, discolora-
tion may still be an issue, in which case you should turn
off your TV or monitor, wait 15 to 30 minutes, and then
turn it back on again. This normally activates the degauss-
ing function, which neutralizes the magnetic field,
thereby removing any discoloration effects. If discolora-
tion problems persist, try moving the speakers away from
your TV or monitor. Note that discoloration can also be
caused by a magnet or demagnetizing tool that’s too close
to your TV or monitor.

Input Signal Warning
The speakers can handle the specified input power when
used for normal music reproduction. If any of the follow-
ing signals are fed to them, even if the input power is
within the specified rating, excessive current may flow in
the speaker coils, causing burning or wire breakage:

Interstation noise from an untuned FM radio.
2.
Sound from fast-forwarding a cassette tape.

Speaker care
Wipe the cabinet occasionally with a dry silica or soft
cloth. For heavier dirt, after dampening a soft cloth in a
weak solution of mild detergent and water and wringing
it out dry, wipe off the dirt. Then, dry immediately with
a clean cloth. Do not use rough material, thinners, alco-
hol or other chemical solvents or cloths since these could
damage the finish, remove the panel lettering, or cause
discoloration. If you are using a chemical cloth, always
follow the instructions that come with the cloth. For dust
accumulated on grilles, use a vacuum cleaner or brush it
off.
