Notes on usage
Do not touch the diaphragm of each speaker unit.
The color and appearance (grain patterns) may vary among the enclosures because
natural wood is used. Depending on lighting conditions, the enclosures may look
different, but this does not indicate damage.
Do not put any object or your hand into either of the ducts located on the rear of the
enclosure.
If there is a foreign object in the duct, do not attempt to take it out by yourself. Please
consult your nearest dealer.

Before attaching the grille frame, confirm its correct mounting orientation. When
attaching, press above the pin to firmly secure it. If the grille frame is protruding
outward (it will not come off), push it all the way in. Attaching the grille frame is
recommended even when not using the speaker in order to protect them from damage.
The speaker can be enjoyed with the grille frame attached, but superior performance
can be achieved by removing the grille frame. When removing the grille frame, take
care not to bend or distort its shape excessively.
Setting the speaker
Speaker placement is one of the most important factors in obtaining high-quality sound.
Observe the following when placing your speaker to obtain full advantage of the speaker
characteristics:
Set up the speaker on a hard, flat place.
Setting the speaker on the rack is recommended (
-
).
Depending on the rack type, you can set the speaker into the rack (
-
).
Do not place the speaker in the following locations:
In places subject to high temperature or direct sunlight
In places subject to excessive dust and dirt
In places subject to high humidity
Near source components (CD players, record players, etc.)
Near magnetic cards (credit cards, commuter passes, etc.)
Magnetic cards may fail due to the magnets in the speaker units.
Nearby devices that can be influenced by magnetism, such as a digital video recorder.
Place those devices more than 5 cm (2 in) away.
Near televisions
The speaker is not magnetically shielded. Therefore, if you use the speaker near CRT-
based televisions, color shading occurs on the television screen.
If color shading occurs, turn off the television, then turn it on again after 15 or 30
minutes. If the color shading persists, increase the distance between the speaker and
television.
AV receiver connections
Selecting the receiver/speaker cords
Select a receiver (not supplied) and speaker cords (not supplied) meeting the following
requirements.
For selecting a receiver:
The speaker impedance is designed as 4 ohms. Excessive sound volume may damage the
speaker, so be aware of the position of the volume level knob on the receiver and avoid
excessive input.
Requirement for selecting speaker cords
In order to output high-quality sound signals, use speaker cords of the minimum necessary
length that are treated with either of the following two fittings at their ends:
With cable cores (less than 4.5 mm (
3
/
16
in) in diameter) bared by stripping the jacket to
10 mm (
13
/
32
in) from each + and - end
The bare cable core may become oxidized over time. In this case, reconnect the speaker
cords after stripping the jacket to expose a fresh segment of cable core at each end. This
will ensure that you can enjoy better sound.
With spade plugs (more than 8 mm (
11
/
32
in) in inner diameter, and less than 12 mm
(
1
/
2
in) in outer diameter)
Connecting to the receiver
Before connecting, turn off the receiver.
Connect the terminals of the speaker to the center speaker of the receiver.
Note
Tighten each binding post securely. Periodically checking the tightness of the binding posts
is recommended to prevent them from becoming loose as time passes.
About aging
The speaker takes some time to provide their best performance. Play the speaker at normal
volume for about 10 hours to break them in.

Precautions
Before turning a receiver or a source component on/off
Set the volume of the receiver to minimum.
If the bass cannot be heard or the phonic positions of instruments are
indefinite
Make sure to connect the speaker cords by ma/– to the appropriate speaker
terminals.
Cleaning of the enclosure
Do not use any type of neutral detergent, benzene, or alcohol because they may damage
the surface finish of the enclosure.
To maintain the fine gloss of the enclosure for a long time, gently wipe off dust using a
soft brush or feather duster, and then wipe the enclosure with the supplied cleaning cloth.
(Do not use any type of scrub brush or sponge.)
Wipe smudges such as fingerprints or oil spots with the supplied cleaning cloth carefully.
When the smudges are hard to remove, wipe them off with a soft cloth soaked in soapy
water, and wrung dry.
Make sure not to damage the enclosure.
The supplied cleaning cloth is washable and can be used repeatedly.
To avoid damaging the speaker
Do not disassemble or modify the speaker units, network circuits, or the enclosure.
If sound is distorted or noise occurs, amplifier power output may be overloading the
speaker units. Turn down the volume, or the speaker units may be damaged.
To avoid damaging the circuits
Do not input the following signals continuously:
FM inter-station noise
High-frequency signals of electronic instruments
High output and high-frequency signals in the fast-forward and rewind modes of a tape
recorder
