• To assure the finest performance, please read
this manual carefully. Keep it in a safe place for
future reference.

• Install the speakers in a cool, dry, clean place
away from windows, heat sources, sources of
excessive vibration, dust, moisture and cold.
Avoid sources of humming (transformers,
motors). To prevent fire or electric shock, do
not expose the speakers to dripping or
splashing.

• To prevent the enclosure from warping or
discoloring, do not place the speakers where
they will be exposed to direct sunlight or
excessive humidity.

• Do not place the following objects on top of the
speakers:

1. Glass, china, etc.

If glass etc. falls by vibrations and breaks,
it may cause personal injury.

2. A burning candle etc.

If the candle falls by vibrations, it may
cause fire and personal injury.

3. A vessel with water in it

If the vessel falls by vibrations and water
spills, it may cause damage to the unit, and/
or you may get an electric shock.

• Do not place the speakers where foreign
objects such as water drips might fall. It might
cause a fire, damage to this unit, and/or
personal injury.

• Do not place the speakers where they are liable
to be knocked over or struck by falling objects.
Stable placement will also ensure better sound
performance.

• Secure placement or installation is the owner’s
responsibility. Yamaha shall not be liable for
any accident caused by improper placement or
installation of speakers.

• Any time you note distortion, reduce the
volume of your amplifier immediately. Make
sure the input power does not exceed the
specified maximum input power, otherwise the
speakers will be damaged.

chemical solvents as this might damage the
finish. Use a clean, dry cloth.

Precautions When Positioning the Speakers

The speaker is constructed with the majority of
the weight located in its upper portion, and is thus
susceptible to falling over if proper care is not
taken to insure its stability. If the speaker falls
over, it may damage the speaker or be the cause of
injury (or even death) to persons and/or damage to
personal property.

■ For safe and proper use of the speaker:

• Position the speaker in a location that is solid,
level, smooth, and low (with respect to the
floor).

• Do not push or apply pressure to the side of the
speaker when moving, or lean objects against
the side of the speaker.

• Do not sit on or set objects on top of the
speaker.

Vibrations or jolts associated with earthquakes
and other phenomena or activities may cause the
speaker to fall over. For safety reasons, using
commercially available products that increase
stability in the speaker is recommended (metal
fittings or chains, etc.).

Placing the Speakers

Place the speakers on a sturdy, vibration-free
surface.

■ Using as Normal Stereo Speakers

To get the best stereo performance, angle the
speakers inward so as to create a triangle, with the
listener at the apex.

■ Using as Front Speakers in a Surround Sound System

Position the speakers both side of your TV. The
positioning of these speakers is important because
they provide a solid anchor for the sound image.
They should be positioned facing the listener at
about ear level, and equidistant from the TV.
