Speaker Precautions
Placement
• The subwoofer cabinet is made out of wood
and is therefore sensitive to extreme tem-
peratures and humidity. Do not put it in
locations subject to direct sunlight or in
humid places, such as near an air condi-
tioner, humidifier, bathroom, or kitchen.
• Do not put water or other liquids close to the
speakers. If liquid is spilled over the speak-
ers, 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 sur-
faces, where they may fall and cause dam-
age, will affect the sound quality.
• The HTX-22HDXPAW Amp/Subwoofer is
designed to be used in the upright vertical
position only. Do not use it in the horizontal
or tilted position.
• If the subwoofer is used near a turntable,
CD/Blu-ray/DVD player/recorder, howling
or skipping may occur. To prevent this,
position the subwoofer away from such
components, or turn down the volume.
• The HTX-22HDXPAW Amp/Subwoofer
generates heat and has vents at the top and
rear to allow this heat to escape. When
installing, leave at least 20 cm (8") of free
space above and behind. Also, leave at least
20 cm (8") of free space at the sides, other-
wise, the performance of the bass-reflex
port may be compromised.
The HTX-22HDXPAW Amp/Subwoofer
uses a non-shielded design. If you’re using
a CRT-type TV, to prevent picture interfer-
ence, position it at least 40 cm (15-3/4")
away from your TV.
Using Close to a TV or Computer
TVs and computer monitors are magnetically
sensitive devices and as such are likely to suf-
fer discoloration or picture distortion when
conventional speakers are placed nearby. To
prevent this, the HTX-22HDXST 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 neu-
tralizes the magnetic field, thereby removing
any discoloration effects. If discoloration
problems persist, try moving the speakers
away from your TV or monitor. Note that dis-
coloration can also be caused by a magnet or
demagnetizing tool that’s too close to your
TV or monitor.
Input Signal Warning
The speakers can handle the specified input
power when used for normal music reproduc-
tion. 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:
1. Interstation noise from an untuned FM
radio.
2. Sound from fast-forwarding a cassette
tape.
3. High-pitched sounds generated by an
oscillator, electronic 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 disconnecting audio cables. (Always
turn off the HTX-22HDXPAW Amp/Sub-
woofer before connecting or disconnect-
ing cables.)
7. Microphone feedback.
