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 grille, push the projections at the corners
into the grille plug holes on the speaker cabinet.

Use with a TV set
In general, Braun tubes used for color TV 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, discoloration or 
distortion of pictures will occur. To allow use with color TV sets, 
etc., this speaker system is provided with magnetic shielding.
Even so, discoloration may still result, depending on the installation 
environment. If discoloration occurs, turn off the power of the TV 
set, wait for 15 to 30 minutes and then turn it on again. This activates 
the self-demagnetizing function of the TV set, improving the display 
condition. If discoloration persists even after performing this remedy, 
move the speaker apart from the TV set. Discoloration may also 
be caused when a magnet or other magnetizing object exists near 
the TV set because of the combined effect.
Speaker care
Your Onkyo speakers are fi nished 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.

Before turning on the amplifi er’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 amplifi er.
● Be sure to connect the speaker cables with correct polarity
(connect the speaker’s positive (+) and negative (-) binding 
posts with the amplifi er’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 amplifi er’s 
corresponding speaker terminals. 
● Pull lightly on the speaker cables to ensure that they are
connected fi rmly.
Placement
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 fl oor 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 specifi c frequency ranges due to 
refl ected sound. To eliminate this resonance, place some 
sound-absorbing material such as a thick curtain in front of the 
doors or walls.
Attaching the speaker stands
Attach the supplied speaker stand at the bottom of each speaker 
cabinet using the supplied screws as shown in the fi gure below.
For better sound quality, you are recommended to attach the 
supplied spacer on the speaker stand.
In addition to the sound quality improvement, attaching the spacers 
also provide non-sliding and stabilizing effects for the speaker 
cabinet.
