Thank you for buying this Pioneer product. Please read through
these operating instructions so you will know how to operate your
model properly. After you have finished reading the instructions,
put them away in a safe place for future reference.
Before you start
• The nominal impedance of this speaker system is 8 ohms.
Connect the speaker system to an amplifier with a load
impedance ranging from 4 to 16 ohms (a model with
“4 – 16
Ω
” displayed on the speaker output terminals).
• Do not touch the speaker cones as they are easily damaged.
In order to prevent damage to the speaker system resulting from
input overload, please observe the following precautions:
• Do not supply power to the speaker system in excess of the
maximum permissible input.
• When connecting or disconnecting anything in your AV
system, make sure the amplifier is switched off.
• When using a graphic equalizer to emphasize loud sounds in
the high-frequency range, do not use excessive amplifier
volume.
• Do not try to force a low-powered amplifier to produce loud
volumes of sound (the amplifier’s harmonic distortion will be
increased, and you may damage the tweeter).
Caution: installation
• Do not place the speakers on an unstable surface. It could
present a hazard if it falls, as well as damaging the equip-
ment.
• Switch off and unplug your AV equipment and consult the
instructions when connecting up components. Make sure you
use the correct connecting cables.
• Do not put a TV or other AV equipment on top of these
speakers. It could present a hazard if it falls, as well as
damaging the equipment.
• Do not attach the speakers to the wall or ceiling, or place them
in a high location. If the speaker grilles are not properly
attached, they could fall off, causing injury.
Caution: in use
• Don’t use the speakers to output distorted sound for long
periods of times. This can result in a fire hazard.
• Do not sit or stand on the speakers or let children play on the
speakers.
• Do not put large or heavy objects on top of the speakers.
WARNING:
Handling the cord on this product or
cords associated with accessories sold with the
product will expose you to lead, a chemical known to
the State of California and other governmental
entities to cause cancer and birth defects or other
reproductive harm.

Installing your speakers
Sounds played through speaker systems are easily affected in
subtle ways by the conditions in the listening space.
• These speakers are bookshelf-type speakers which will give
their best performance when placed on a solid, level surface
off the floor. Placing the speakers directly on the floor will
result in boomy, undefined sound, and we strongly recom-
mend using speaker stands for optimal performance. Ideally,
the tweeters should be at about ear level when seated in your
listening position.
• Do not attach these speakers to the wall or ceiling. They may
fall off and cause injury.
Pioneer cannot take responsibility for injuries or accidents
arising from improper mounting of these speakers on a wall or
ceiling.
• Speakers are heavy, so make sure the surface where you
install the speakers is solid. For good sound, the speakers
should be about 20cm away from the back wall and at least
50cm away from the side wall.

• If you’re using these speakers for your TV sound, install them
at equal distances either side of the TV and point them in the
same direction as the TV.
• If the room has a lot of reverberation, we recommend hanging
heavy fabric on the walls, and/or putting a carpet on the floor
to damp the sound. For best results, cover walls completely.
• Do not place the speaker where they will be in direct sunlight,
and avoid positioning them near heaters and air conditioners.
This may cause warping and discoloration of the speaker
cabinet and damage the speakers.
• These speakers are heavy. Placing them on an unstable
surface is dangerous, and should be avoided.
Not applicable to S-HF11C
• Place the speakers equal distances from your listening
position for good stereo sound. Use speaker cords of the
same length for each speaker.
