Instruction Manual

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.

• 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 smoky

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 system.

• 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.

• 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 deck

3. High-frequency sound generated by an

oscillator, an electronic musical instrument, 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 tweeter since

they use speakers with strong magnets. Otherwise,

the objects may be attracted, causing injury or

damaging the diaphragm.

Before using this unit

Precaution on use

• The two speakers are identical, so it doesn’t matter

which one you use on the left or right.

• Turn the sound volume to the minimum and

disconnect the power cord from the amplifier before

connecting the speaker cables.

• The nominal impedance of this speaker system is

6 Ω. Use only amplifiers capable of handling this

impedance.

• Use the supplied speaker cables to connect between

speaker’s input terminals and the amplifier’s speaker

terminals as illustrated on the below

• Use the red line wires to connect the positive (+)

terminals.

• 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.

Connecting to AV amplifier

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.

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 reproduced 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 walls.

1. Strip the insulation of speaker cables,

and twist the core wires tightly.

2. Loosen the terminal screw and insert

the wire into the hole (until the core

wires are inserted fully).

3. Fasten the terminal screw.
