Warnings, Cautions and Others
7 Precautions for installation
• To avoid personal injury or accidentally
dropping the unit, have two persons unpack,
carry, and install the unit.
• 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 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
speakers.
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.
• Do not lean against the speakers, as the speakers could fall
down or break, possibly causing an injury. Especially be
careful that children do not lean against them.
7 Precautions for daily use
• 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 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
injury.
Preparation
7 Checking the supplied accessories
• Feet (2) • Speaker grille (1)
• Screws (4) • Spacers (4)
If any item is missing, contact your dealer immediately.
7 Attaching the feet
To prevent the speaker from falling over, be sure to attach
the supplied feet to the speaker.
• Take care not to drop the feet or speaker while assembling;
otherwise, it may cause damage to the floor or injury.
• 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.

7 Connecting the speaker system to the amplifier
Before connection—
• Turn off the power to the amplifier before connecting the
speaker system; otherwise, the speakers may be damaged.
• 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 SX-LT55 is
150 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.
• When using a microphone, do not aim it at the speakers or
use it near the speakers; otherwise, the howling which occurs
may damage the speakers.
• Before replacing the cartridge, always turn off the power to the
turntable; otherwise, the clicking noise may damage the
speakers.
• Use speaker cords as follows;
– 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
speakers.
– 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.
7 Connecting the speaker cord
Connect the “INPUT” terminal of the speaker to the speaker
terminal of the amplifier.
Rotate the speaker terminal

7 Bi-wiring connection
This speaker is bi-wireable. Comparing with the conventional
connection, the bi-wiring connection makes the sound field
larger, deeper, and richer.
1
Loosen all speaker terminal knobs and detach the
short-circuit plates.

2
Connect the “FULL RANGE” terminals and “LOW
FREQUENCY” terminals separately to the speaker
terminals of the amplifier.
