Warnings, Cautions and Others
7 Precautions for installation
7 Precautions for daily use
• Do not install the speakers on an uneven surface or in a place
subject to vibration; otherwise, they may fall over, causing
damage or injury.
– Take the occurrence of earthquakes or other
physical shocks into consideration when
selecting the installation place, and secure the
speakers thoroughly.
• To maintain the appearance of the speakers
Wipe with a dry, soft cloth if the cabinet should become dirty.
If very dirty, apply a small amount of water or neutral detergent
to the cloth and wipe clean, then wipe with a dry cloth.
• To prevent deformation or discoloration of the
cabinet, do not install the speakers where they are
exposed to direct sunlight or high humidity, and
avoid installation near air conditioning outlets.
• Speaker vibrations may cause howling. Place the
speakers as far away from the player as possible.
• The speakers are magnetically shielded to avoid
color distortions on TVs. However, if not installed properly, it
may cause color distortions. So, pay attention to the following
when installing the speakers.
– When placing the speakers near a TV set, turn off the TV’s
main power switch or unplug it before installing the
Then wait at least 30 minutes before turning on the TV’s
main power switch again.
Some TVs may still be affected even though you have followed
the above. If this happens, move the speakers further away
from the TV.
• Tuner reception may become noisy or hissing if a speaker is
installed near the tuner. In this case, leave more distance
between the tuner and the speakers or use an outdoor
antenna for better tuner reception without interference from
the speakers.
• To improve the sound field
– It is recommended to leave a space of more than 50 cm
between the speakers and the wall.
– If the speakers are facing a solid wall or glass
door, etc., it is recommended to furnish the wall
with materials that absorb sounds, for example
by hanging up thick curtains, to prevent
reflections and standing waves.
• To use the speakers without any trouble
– Do not reproduce sounds at so high a volume that they are
distorted; otherwise, the speakers may be damaged by
internal heat buildup.
– When moving the speakers, do not pull the speaker cords;
otherwise, the speakers may fall over, causing damage or

7 Attaching the base plate
7 To remove the speaker grille
To prevent the speaker from falling over, be sure to attach the
supplied base plate to each speaker.
To remove the speaker grille, insert your fingers at the bottom
of the speaker grille, then pull upward.
• Take care not to drop the base plate or speaker while
assembling; otherwise, it may cause damage to the floor or
• Ensure enough space for assembly and installation.
• Place a large, thick cloth on the floor where you assemble the
speaker, so you can protect the floor and the speaker itself.
• Do not touch the speaker units.
Turn the speaker upside down and attach the base plate
securely on the bottom of the speaker with the supplied
screws as illustrated.
• Prepare a Phillips screw driver.
• Make sure that the FRONT arrow on the top of the base plate
points the front side of the speaker.

7 Connecting the speaker system to the amplifier
7 Connecting the speaker cord
Before connection—
• Turn off the power to the amplifier before connecting the
speaker system; otherwise, the speakers may be damaged.
Connect the speaker cord to the speaker as illustrated.
• The impedance of the speaker is 6 Ω. Before connecting it to
your amplifier, check the speaker impedance range of your
amplifier. If the impedance of this speaker is out of the speaker
impedance range indicated on the amplifier, you cannot
connect this system to the amplifier.
• The maximum power handling capacity of the SP-F508 is
100 W. Excessive input will result in abnormal noise and
possible damage.
• Be sure to turn down the volume level to prevent unwanted
noise before performing following operations:
– Turning on or off other components,
– Operating the amplifier,
– Tuning FM stations,
– Fast-forwarding a tape,
– Continuously reproducing high frequency oscillation or high
pitch electronic sounds.
• Make sure to match the polarity (ª and ·); otherwise, the
surround effect will become less effective.
Before connecting:
Twist and remove the insulation at the end
of each speaker cord.

turntable; otherwise, the clicking noise may damage the
• Speaker cords are supplied to the speakers. When using other
speaker cords, observe the following;
– Buy thick speaker cords rather than thin cords, and make
them as short as possible for connection.
– Use speaker cords of the same length for both left and right
– Do not use long speaker cords; otherwise, the sound quality
may deteriorate.
– Using a special speaker cord such as a litz wire, a coaxial
cable, or a cord which has the specified connecting
directionality may influence the sound quality.
