Placement
D-407F Front speaker system
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.
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.
• Exercise due care to install and secure the cabinet; the
sustainability of the screws may vary depending on the
quality and/or location of the wall where they are tightened.
You may want to consult with a professional installer.

Caution:
• Allow for secure placement of the speaker; the cabinet is
very tall and tends to fall down under unstable conditions.
Do not place it on an unstable location such as shaky or
sloping table, platform or thick carpet. Otherwise it could
cause injury when dropping or falling.
• You can secure the cabinet to the wall, etc. by using a
durable cord or chain along with cup hooks: Find a hole on
the either side of backside the cabinet, and screw into
each hole the cup hook of about 4mm in diameter and
15mm long, and then secure the cabinet to the wall, etc.
with the cord or chain.
