Instruction Manual
• 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.
Precautions
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.
Thank you for purchasing an Onkyo Speaker
System.
Please read this manual thoroughly before using
it. Following the instructions in this manual will
enable you to obtain optimum performance and
listening enjoyment from your new Speaker System.
Please retain this manual for future reference.
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 dis-
connecting 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 may be attracted toward the magnet,
causing injury, or damage to the tweeter diaphragm.

The two speakers are identical, so it doesn’t matter
which one you use on the left or right.
Using Close to a TV or Computer
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. To prevent this, the speakers feature
internal magnetic shielding. In some situations, however, discoloration may still be an issue. In this case,
turn off your TV or monitor, wait 15 to 30 minutes, and
then turn it back on again. This normally activates the
degaussing function, which neutralizes the magnetic
field, thereby removing any discoloration effects. If discoloration 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.
Note:
If the speakers are placed close to a TV or monitor, due
to the electromagnetic waves radiated by the TV or
monitor, you may hear noise from the speakers even
after your amplifier has been turned off. To prevent this,
position the speakers away from your TV or monitor.
Removing the Speaker Grilles
You can improve the sound quality by attaching the
included cork spacers to raise the speakers off the surface
and reduce the contact area. The cork spacers also make
the speakers stable and prevent them from slipping.

Connecting the Speakers
• 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 4Ω. 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.
