Speaker placement
■ Layout of your speaker system
■ Satellite speaker
Satellite speakers
Installation using commercially-available stands and
fixtures
• Front left/right speakers and center speakers
These three speakers should be placed in front of the
listener.
The speaker bottom and rear are equipped with screw holes so
that you can attach commercially-available stands or
mounting fixtures for a variety of mounting options. (Two M5
screw holes, 60 mm pitch on the bottom and one M5 screw
hole on the rear.)
All three speakers should be placed at the same level.
Placement should be such so that the speakers all aim at the
ears of the listener when the listener is listening to music or
watching the screen. The center speakers enhance the sound
effects from the two front speakers and add clarity to
movements in the sound for a much richer sound image.
Note:
When attaching an accessory item
to a speaker, be careful of the
M5 screw
length of the screws used. Use
only screws that provide the
required strength with a screw
length between 7 and 12 mm.
• Surround left/right speakers
5 mm
Surround speakers should be placed to the side of the
listener or behind the listener. These speakers produce
sound movements in all directions, create a sound
environment that reflects the background, and create the
sensation of being in the middle of the action.
7 to 12 mm
Subwoofer
The subwoofer can be installed anywhere in the room, but in
most situations you will obtain the best results by placing the
subwoofer to the side near a corner of the room. The quality
and level of the bass sounds from the subwoofer will differ
depending on the location where the subwoofer is placed and
the layout of the room, so it is recommended to place the
subwoofer in several locations and find the position that
provides the best results.
■ Using spacers
Attaching the supplied spacers is recommended for obtaining
the best sound quality. Also, by attaching the provided
spacers, the speakers will not slide easily for a more stable
installation.

• Connect the input terminals on the rear of the satellite
speakers to the speaker output terminals on the AV
amplifier or receiver using the supplied speaker cables as
shown in the diagram to the left.
■ Connecting the satellite speakers
• Each speaker cable should be connected to the speaker
terminal of the same color.
The speaker’s terminals are colored as follows.
Note:
The nominal impedance of this speaker system is 6 Ω. Use
only amplifiers capable of handling this impedance.

Adjustment procedure
■ Adjusting the cut-off frequency and volume
Use the cut-off frequency (FREQUENCY) and volume
(OUTPUT LEVEL) knobs on the front of the subwoofer (SL-
105) and adjust the levels to the desired level in accordance
with the layout of your room and the positioning of all your
components. If the playback frequency range and volume of
the subwoofer are not set to proper levels, distortions in the
playback characteristics can result.
Although it is recommended to set the cut-off frequency and
output level settings as high as possible, it is difficult to notice
the extremely low frequency bass sounds. This makes it
possible to accidentally set the volume level too high. In order
to prevent this, back the levels down just a bit to ensure the
proper balance.
Note:
Make sure that the input levels do not reach excessive levels.
The HTP-L50 is designed for playing back music at a normal
volume, but if the input levels are set to enormous levels, it
may damage the speakers. Also, always first lower the volume
at the amplifier before changing the settings of any switches
to prevent accidental damage.

For details on how to connect the speaker cables, see the
previous page.
Notes:
• When connecting the speaker cables, be sure not to mistake
the (+) and (–) and the L (left) and R (left). If the speaker
cables are connecting incorrectly, there will be a loss of
fidelity in the bass sound ranges.
• The speakers connected to the SL-105 SPEAKER LEVEL
OUTPUT terminals must have an impedance equal to or
greater than the rating indicated on the amplifier connected
to the SPEAKER LEVEL INPUT terminals. Otherwise,
amplifier damage may occur.
• Do not use BTL (Balanced Transformer-Less) type
amplifiers. Using a BTL amplifier may cause damage to
both the amplifier and the subwoofer. Ordinary amplifiers
are not BTL amplifiers. For details, see the amplifier’s
instruction manual.

Precaution on use
• If the unit is used near a turntable or CD player, howling or
skipping of sound may occur. To prevent this, move the
unit away from the turntable or CD player or otherwise
lower the unit’s output level.
■ Placement
• The enclosure is made of wood and therefore sensitive to
extreme temperatures and humidity. Avoid placing the unit
in locations subjected to direct sunlight or in humid places
such as near an air conditioner, bathroom or kitchen, as
well as in locations subjected to soot or steam such as near
a kitchen table and humidifier. Otherwise, damage may
occur.
• This unit can handle the specified input power when it is
used for ordinary music reproduction. If the following
abnormal signals are fed to the unit, however, an
overcurrent may flow in the internal circuits, causing
burning or breakage of the wires even if the input power is
below the specified rating.
• Keep water or other liquids away from the unit. If water is
spilled into the unit, not only the unit but also the
connected amplifier (receiver) may be damaged.
1. Special test signals produced by audio checking CD, etc.
2. Sound produced when connecting or disconnecting
audio connection cables.
(Always turn off the amplifier’s power before
connecting or disconnecting cables.)
• Place the unit on a level and rigid surface free from
vibration.
• Slip-proof spacers are provided with the SL-105. If the SL-
105 is to be placed on flooring or other similar surfaces,
attach these spacers to the bottom surface at the corners.
This will not only prevent scratching, but also provide a
stable footing. However, note that depending on the
surface, the spacers may leave markings.
3. Howling when a microphone is used.
4. Abnormal sound produced when bass-range signals are
excessively boosted by using the amplifier’s (receiver’s)
tone controls, a graphic equalizer, etc., or when a source
whose bass range is abnormally boosted is being played.
This state called “rattling” occurs when the signal is
beyond the driver’s reproduction capacity. Although it is
not a sign of damage, decrease the speaker output level
to prevent damage to the driver.
• This unit is designed to be used in the upright vertical
position only. Do not use it in the horizontal or tilted
position.
