Various Mounting Methods
Front Speaker Bases
Wall Mounting
If you intend to stand the front speakers on the floor or
on a TV stand or AV stand, you should attach the sup-
plied front speaker bases. To do this, align the mounting
holes in the base with base inserts on the front speaker’s
rear panel, and secure by using four of the supplied fix-
ing screws.
The front speakers, center speaker or surround speakers
can easily be wall mounted by using the keyhole slots. To
prevent the speaker from vibrating against the wall,
attach four of the supplied spacers to the keyhole fins on
the rear of each speaker.
■ Mounting vertically
To mount the front speakers or surround speakers verti-
cally, use the keyhole slot shown to hang each speaker on
a screw that’s securely screwed into the wall.

Caution:
A mounting screw’s ability to support a speaker depends
on how well it’s anchored to the wall. If you have hollow
walls, screw each mounting screw into a stud. If there are
no studs, or the walls are solid, use suitable wall anchors.
Use screws with a head diameter of 9.5 mm or less and a
shank diameter of 4 mm or less. With hollow walls, use
a cable/pipe detector to check for any power cables or
water pipes before making any holes.
Note:
The portion of the screw that goes into the speaker’s
threaded insert should be between 5 mm and 9 mm long,
as shown.

Leave a gap of between 7 mm and 10 mm between the
wall and the base of the screw head, as shown.

Read the following before connecting your speakers:
• Turn off your amp before making any connections.
Connecting the Subwoofer
• The nominal impedance of these speakers is 8 Ω. Use

• Pay close attention to speaker wiring polarity. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only negative (–) termi-
nals. If the speakers are wired incorrectly, the sound
will be out of phase and will sound unnatural.

About Home Theater
Enjoying Home Theater
The SKS-HT230’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.
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 equi-
distant from the TV. Angle them inward so as to create a
triangle, with the listener at the apex.
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.
Right
Subwoofer
The subwoofer handles the bass
sounds of the LFE (Low-Fre-
quency Effects) channel. The vol-
ume and quality of the bass output
from your subwoofer will depend
Left
on its position, the shape of your
listening room, and your listening
position. In general, a good bass
sound can be obtained by install-
ing the subwoofer in a front cor-
ner, or at one-third the width of the
wall, as shown.
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 60–100 cm above ear level.
Ideally they should be equidistant
from the listener.

Caring forYour Speakers
Placement
Setting the Subwoofer Level
• The speaker cabinets are made out of aluminum 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 condi-
tioner, humidifier, bathroom, or kitchen.
To set the level of the subwoofer, use the OUTPUT
LEVEL control. Set it so that bass sounds are evenly bal-
anced 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 sub-
woofer 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.
• Do not put water or other liquids close to the speakers.
If liquid is spilled over the speakers, the drive units
may be damaged.
• As explained in this manual, mount the speakers on a
wall, on the supplied bases, otherwise, they may fall,
causing personal injury or damage to the speakers.
OUTPUT
LEVEL
• Use commercially available speaker mounts and
brackets to mount the surround speakers on a wall.
• Speakers with bases 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.

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 SKS-HT230 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 dis-
coloration 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.

The SKS-HT230 speakers contain strong magnets, so do
not put magnetic or iron objects such as screwdrivers
close to them. If you do, the object may be attracted to
the magnets, causing personal injury or damage to a
speaker cone.

Operating Precautions
The SKS-HT230 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:
Frequency
1. Interstation noise from an untuned FM radio.
2. Sound from fast-forwarding a cassette tape.
3. High-pitched sounds generated by an oscillator, elec-
tronic musical instrument, and so on.
4. Amplifier oscillation.
5. Special test tones from audio test CDs and so on.
6. Thumps and clicks caused by connecting or discon-
necting audio cables (Always turn off your amplifier
before connecting or disconnecting cables.)
7. Microphone feedback.
