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, wipe with a cloth applied a small amount of 
water or neutral detergent, then wipe with a dry cloth.
– Do not use chemicals such as benzine and thinner for
cleaning the cabinet.
•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
• Speaker grille (1)
If any item is missing, contact your dealer immediately.
7 Adjusting the feet
If the speaker is unstable, adjust each foot until it stands stably.
•To avoid personal injury, and physical damage both to the 
speaker and to the floor be careful not to drop the speaker on 
your feet.
•Have two persons to adjust the feet to avoid falling off the 
speaker.
• Do not touch the speaker units while adjusting the feet.
• When installing the speaker on the floor, be careful not to 
place it over your hands.

7 Connecting the speaker system to the amplifier
Before connecting:
• Make sure to match the polarity (ª and ·) when connecting
the speaker cords.
•Turn off the power to the amplifier before connecting the 
speaker system; otherwise, the speakers may be damaged.
• The impedance of each speaker is 6 Ω. 
If this does not match with the speaker impedance range 
indicated on the amplifier, you cannot connect this system to 
the amplifier.
• The maximum power handling capacity of the SX-L77 is 
180 W. Excessive input will result in abnormal noise and 
possible damage.
• Be sure to turn down the volume level on the amplifier 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
– Connecting or disconnecting a microphone
• 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 both 
to the amplifier and 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.
7 Conventional connection
1
Loosen the knobs of the “FULL RANGE” terminals.
2
Fit the speaker cords into the grooves of the “FULL 
RANGE” terminals, then tighten the knobs to secure the 
speaker cords and short-circuit plates.

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.
