Thank you for your purchase of the 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.
Before using this unit
The speaker cabinet is made of wood and is therefore
sensitive to extreme temperatures and humidity. Avoid
placing the speaker systems in locations subjected to direct
sunlight, or in smokey or in humid places, such as near an
air conditioner, humidifier, bathroom, or kitchen. Doing so
may result in damage to the speaker.
Place the unit on a rigid, level surface. Placing it on a
slanted surface or weak base not only may cause the unit to
fall, but also results in decreased sound quality.
Be sure to turn off your amplifier before connecting the
speaker system. Connecting them with the amplifier's power
on may result in damage to the amplifier or the speaker
Keep water or other liquids away from the unit. If water is
spilled into the unit, not only the unit but also the speakers
themselves may be damaged.
Name and function of each part
Precaution on use
This speaker system can handle the specified input power
when it is used for ordinary music reproduction. If the
following abnormal signals are fed to the speaker, however,
an overcurrent may flow in the internal circuits, causing
burning or breakage of the wires even if the input power is
below the specified rating.
1. Noise produced when FM station is not tuned in
2. Sound produced when fast-forwarding cassette tape
3. High-frequency sound generated by an oscillator, an
electronic musical instruments, etc.
4. Oscillating amplifier signals
5. Special test signals produced by audio checking CD, etc.
6. Sound produced when connecting or disconnecting audio
connection cables (Always turn off the amplifier's power
before connecting or disconnecting cables.)
7. Howling when a microphone is used
Do not place magnetic objects such as screwdrivers and iron
parts near the speaker system since they use speakers with
strong magnets. Otherwise, the objects may be attracted,
causing injury or damaging the diaphragm.
Turn the sound volume to the minimum and turn OFF the
amplifier power switch (POWER) before connecting the speaker
The nominal impedance of this speaker system is 6
. Use only
amplifiers capable of handling this impedance.
Use the supplied speaker cables to connect between speaker 's
binding posts and the amplifier's speaker terminals as illustrated
Connect the speaker cables securely to the terminals, with the
core wires twisted properly. In this case, make sure that the core
wires do not touch each other. Note that a short circuit in core
wires may result in damage to the amplifier.
6 This speaker system uses banana-plug compatible binding
Connect the Right and Left speakers (as viewed from the
listening position) to the amplifier's corresponding Right and Left
speaker terminals.
Front Speaker System
Before turning on the amplifier's power switch:
Make sure that the positive (+) and negative (­) speaker
cables do not contact each other. Otherwise, a short-circuit
may occur, causing damage to the amplifier.
Be sure to connect the speaker cables with correct polarity
(connect the speaker's positive (+) and negative (­) binding
posts with the amplifier's corresponding speaker terminals).
Reversed polarity results in impaired bass-range
reproduction, causing mislocalization of the sound image.
Also, be sure to connect the Right and Left speakers with
the amplifier's corresponding speaker terminals.
Pull lightly on the speaker cables to ensure that they are
connected firmly.
Ordinary connection (single-wiring)
1. Loosen the LOW-FREQUENCY binding post screws, with the
jumper bars attached.
2. Insert the speaker wires to the connection holes. Fasten the
screws securely again.
* To use banana-plug speaker cables, insert the banana plug
into the center hole of each binding post.
Make sure that the HIGH-FREQUENCY jumper bars are not loosened.
Bi-wiring connection (Remove the attached jumper bars.)
1. Using two sets of speaker cables, connect the HIGH FRE-
QUENCY and LOW-FREQUENCY binding posts independently
to your amplifier.
2. On the amplifier, connect the speaker cables to the speaker
output terminals paying close attention to maintain consistent
polarity (See below.).
Remove the
jumper bars.

Use with a TV set
In general, Braun tubes used for color television sets, etc. are
extremely sensitive and can be affected even by the magnetism of
the earth. If a speaker system is used near them, therefore, discol-
oration or distortion of pictures will occur. To allow use with color
television sets, etc., this speaker system is provided with magnetic
Even so, discoloration may still result, depending on the installation
environment. If discoloration occurs, turn off the power of the
television set, wait for 15 to 30 minutes and then turn it on again.
This activates the self-demagnetizing function of the television set,
improving the display condition. If discoloration persists even after
performing this remedy, move the speaker apart from the television
set. Discoloration may also be caused when a magnet or other
magnetizing object exists near the television because of the
combined effect.
The sound quality a speaker system reproduces varies greatly
depending on the construction and area of the room where it is
installed, as well as the location and size of the furniture. For better-
quality sound, observe the following precautions.
Avoid placing the speaker system on an elevated object such as
on concrete blocks. Instead, place it on a rigid floor surface with
minimal vibration. Also note that high-quality bass cannot be
obtained if the speaker system is unstably positioned. Generally
speaking, placing the speaker system on several small-diameter
supports results in better bass than placing it directly on the
installation surface. Moreover, if you feel the bass reproduced by
the system is too weak, move the speaker system closer to the
wall behind it. You can thus control the strength of the repro-
duced bass by the position of the speakers.
In many rooms, the furniture and wall affect the reproduced
sound quality. For stereo sound reproduction, placing the Right
and Left speakers in the same condition produces the best
results. If they are placed in extremely different conditions, the
Right- and Left-channel balance will be adversely affected.
The ideal placement of the speaker system is as follows:
Imagine an equilateral triangle and position the Right and Left
speakers on both ends of the base. The ideal listening position is
at or slightly to the rear of the triangle apex.
Glazed doors or surrounding walls in front of the speaker system
may cause the resonance of specific frequency ranges due to
reflected sound. To eliminate this resonance, place some sound-
absorbing material such as a thick curtain in front of the doors or
Attaching and detaching the speaker grilles
This speaker system uses detachable grilles. Use the following
method to attach or detach the grilles.
1. While holding the bottom edge of the speaker grille with your
both hands, pull it gently toward you to remove the bottom of
the grille.
2. In the same way, gently pull the upper edge of the speaker
grille toward you to remove it from the main unit.
3. To replace the grill, push the projections at the corners into
the grille plug holes on the speaker cabinet.
Speaker care
Your Onkyo speakers are finished with a very high quality
polymer laminate covering that serves to protect the wood
speaker cabinet.
Wipe the cabinet periodically with a dry, silicon-embedded or
plain soft cloth.
The covering may be cleaned with a soft cloth moistened with
water and a mild soap. Avoid the use of furniture polishes or
harsh cleansers.
Use a soft brush or hand vacuum cleaner to remove dust and
lint from the grille material.
