About Home Theater
Enjoying Home Theater
The HTP-320’s great sound means that you can enjoy surround sound with a real sense of movement in your own
home—just like being in a movie theater or concert hall.
Center speaker
This speaker enhances the front left and right
speakers, making sound movements distinct
and providing a full sound image. In movies it’s
used mainly for dialog.
Position it close to your TV facing forward at
about ear level, or at the same height
as the front left and right speakers.
Put it somewhere where
it won’t slide around or fall.
Subwoofer
The subwoofer handles the bass
sounds of the LFE (Low-Frequency Effects) channel. The volume and quality of the bass output
from your subwoofer will depend
on its position, the shape of your
listening room, and your listening
position. In general, a good bass
sound can be obtained by installing the subwoofer in a front corner, or at one-third the width of the
wall, as shown.
1/3
Left
(SKM-320S)
Surround left and right speakers
These speakers are used for precise sound positioning and to
add realistic ambience. Position them at the sides of the listener, or slightly behind, about 2–3 feet (60–100 cm) above
ear level. Ideally they should be equidistant from the listener.
Front left and right speakers
These output the overall sound. Their role in a home theater
is to provide a solid anchor for the sound image. They should
be positioned facing the listener at about ear level, and equidistant from the TV. Angle them inward so as to create a
triangle, with the listener at the apex.

(SKM-320S)
Wall-mounting the surround speakers
If the surround speakers are to be wall-mounted, make sure
that the walls are strong enough to support the speaker’s
weight. The weight that mounting screws can support varies
greatly depending on the wall material and the position of the
reinforcing ribs embedded in the wall.
Use long screws with a head diameter of 1/4 inch (6.3 mm) or
less and a shank diameter of 1/8 inch (3.5 mm) or less. (We
recommend that you consult a home installation professional.)
5
Connecting the
Speakers
Read the following before connecting your speakers:
• Turn off your amp before making any connections.
• Pay close attention to speaker wiring polarity. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only negative (–) terminals. If the speakers are wired incorrectly, the sound
will be out of phase and will sound unnatural.
• Be careful not to short the positive
and negative wires. Doing so may
damage your amp.
Connecting the Speaker Cables
Use the cables to connect each speaker’s
1
input terminals to the corresponding
speaker output terminals on your
HT-R320 or other receiver.
To make a connection, while
pressing the terminal lever,
insert the wire into the hole, and
then release the lever.
Make sure that the terminals are
gripping the bare wires, not the insulation.
Connecting the Power
Cord
Notes:
• Before connecting the power cord, connect all of your
speakers and AV components.
• Turning on the SKW-320X may cause a momentary
power surge that might interfere with other electrical
equipment o the same circuit. If this is a problem, plug
the SKW-320X into a different branch circuit.
Adjustment
Setting the Subwoofer Level
To set the level of the subwoofer, use the OUTPUT
LEVEL control. Set it so that bass sounds are evenly balanced with the treble sounds from the other speakers.
Because our ears are less sensitive to very low bass
sounds, there’s a temptation to set the level of the subwoofer too high. As a rule of thumb, set the subwoofer
level to what you think is the optimal level, and then
back it off slightly.

Placement
• The speaker cabinets are made out of wood and are
therefore sensitive to extreme temperatures and
humidity, do not put them in locations subject to direct
sunlight or in humid places, such as near an air conditioner, humidifier, bathroom, or kitchen.
• Do not put water or other liquids close to the speakers.
If liquid is spilled over the speakers, the drive units
may be damaged.
• Speakers should only be placed on sturdy, flat surfaces
that are free from vibration. Putting them on uneven or
unstable surfaces, where they may fall and cause damage, will affect the sound quality.
• Subwoofer is designed to be used in the upright vertical position only. Do not use it in the horizontal or
tilted position.
• If the unit is used near a turntable or CD player, howling or slipping of sound may occur. To prevent this,
move the unit away from the turntable or CD player
otherwise lower the unit’s output level.
Using Close to a TV or Computer
TVs and computer monitors are magnetically sensitive
devices and as such are likely to suffer discoloration or
picture distortion when conventional speakers are placed
nearby. To prevent this, the SKF-320F and SKC-320C
speakers feature internal magnetic shielding. In some
situations, however, discoloration may still be an issue,
in which case you should turn off your TV or monitor,
wait 15 to 30 minutes, and then turn it back on again.
This normally activates the degaussing function, which
neutralizes the magnetic field, thereby removing any discoloration effects. If discoloration problems persist, try
moving the speakers away from your TV or monitor.
Note that discoloration can also be caused by a magnet or
demagnetizing tool that’s too close to your TV or monitor.
Do not place SKM-320S close to TV or a computer monitor because it has no magnetic shield.
Operating Precautions
The HTP-320 speakers can handle the specified input
power when used for normal music reproduction. If any
of the following signals are fed to them, even if the input
power is within the specified rating, excessive current
may flow in the speaker coils, causing burning or wire
breakage:
Interstation noise from an untuned FM radio.
Sound from fast-forwarding a cassette tape.
High-pitched sounds generated by an oscillator,
electronic musical instrument, and so on.
Amplifier oscillation.
Special test tones from audio test CDs and so on.
Thumps and clicks caused by connecting or disconnecting audio cables (Always turn off your amplifier
before connecting or disconnecting cables.)
Microphone feedback.
Speaker Care
Wipe the cabinet occasionally with a dry silica or soft
cloth. For heavier dirt, after dampening a soft cloth in a
weak solution of mild detergent and water and wringing it
out dry, wipe off the dirt. Then, dry immediately with a
clean cloth. Do not use rough material, thinners, alcohol or
other chemical solvents or cloths since these could damage
the finish, remove the panel lettering, or cause discoloration. If you are using a chemical cloth, always follow the
instructions that come with the cloth. For dust accumulated
on grilles, use a vacuum cleaner or brush it off.
