The two speakers are identical, so it doesn’t matter which one you use on
the left or right.

TVs and computer monitors are magnetically sensitive devices and as such
are likely to suffer from discoloration or picture distortion when
conventional speakers are placed nearby. Note that discoloration can also
be caused by a magnet or demagnetizing tool that’s too close to your TV or
monitor.

• Before connecting the speakers, disconnect your amplifier’s power cord
from the wall outlet and set its volume control to minimum.

• The speaker’s rated impedance is 4 Ω. Make sure you connect an
amplifier that is compatible with a 4 Ω impedance.

• Use the supplied speaker cables to connect the speakers to your amplifier
as shown.

The type of speaker terminals used on the receiver and their position
depends on the model. Refer to the receiver’s instruction manual for details
on connecting speakers to the receiver.

• Make sure the speaker’s positive (+) terminals are
connected to the amplifier’s positive (+) terminals, and
the speaker’s negative (–) terminals are connected to
the amplifier’s negative (–) terminals.

• Make sure that the positive (+) and negative (–) wires
are not touching each other. If they are, a short circuit
may occur, damaging your amplifier.

To maintain the appearance of the speakers, you should periodically wipe
them with a soft, dry cloth. Do not use abrasive cloths, thinners, alcohol, or
other solvents that may damage the finish.

Before Using Your New Speakers

• The speaker cabinets are made out of wood and are therefore
sensitive to extreme temperatures and humidity. Do not use
them in locations subject to direct sunlight or in humid places,
such as near an air conditioner, humidifier, bathroom, or
kitchen.

• Place the speakers on sturdy, flat surfaces. Putting them on
uneven or unstable surfaces where they may fall and cause
damage will affect the sound quality.

• Do not keep water or other liquids close to the speakers. If a
liquid is spilled over them, the woofer and tweeter inside may be
damaged.

• Do not handle the speakers with wet or damp hands.

In catalogs and on packaging, the letter at the end of the product name
indicates the color. Specifications and operation are the same regardless
of the color.

The speakers can handle the specified input power when used for normal
music reproduction. If they’re fed any of the following signals, even if the
input power is within the specified rating, excessive current may flow in
the speaker coils, causing burning or wire breakage:

1. Interstation noise from an untuned FM radio.

2. Audio from a cassette that’s being fast-forwarded.

3. High-pitched sounds generated by an oscillator, electronic musical

instrument, and so on.

4. Amplifier oscillation.

5. Special test tones from audio test CDs and so on.

6. Thumps and clicks caused by connecting or disconnecting audio cables

(always turn off your amplifier before connecting or disconnecting
cables).

7. Microphone feedback.

The speakers contain powerful magnets. Do not put metal items, such as
screwdrivers, close to the speakers, as they damage to the tweeter
diaphragm.
