finished reading the instructions, put them away in a safe place for future reference.
This speaker system is designed for in-wall installation.
The design features provide for a wide range of
placement and listening position options.
This speaker system is designed with CST (Coherent
Source Transducer) technology to assure excellent
sound quality. CST sound delivery is extremely smooth
and coherent. All sound - direct and reflected - arrives at
the listening position with matched timbre.
This speaker system is also paintable so that they may be
matched to your room decor.
Before you start

. Connect the speaker system to an amplifier
capable of driving an impedance of at least 6
This product incorporates auto-resetting overload
protection technology to help avoid damage to the
speakers. However, please observe the following
· Do not supply amplification power to the speaker
system in excess of the maximum permissible
input, which could damage the speaker and cause
a hazard from overheating.
· If using a graphic equalizer to boost sounds in the
high-frequency range, do not use excessive
amplifier volume.
· Do not try to force a low-powered amplifier to
produce high sound levels as the amplifier's
harmonic distortion will be increased, and you may
damage the speaker.

What's in the box
Standard surround setup
Sounds reproduced through speaker systems are easily
affected in subtle ways by the conditions in the listening
space. To assure optimum performance from this
speaker system, give adequate consideration to the
installation location before setup.
Use the graphic below as a guide to determine optimal
speaker placement.
· Place the left and right speakers equal distances
from your listening position for good stereo imaging.
Use speaker cables of the equal length for each
· Keep the speaker system at least 50 cm (20 in.) away
from the edge of the wall or ceiling. If this is not
possible, adjust the sound balance by using the
speakers' treble level control.
· This speaker system is not magnetically shielded. It
should therefore not be placed near TVs or monitors
that are sensitive to magnetic fields, as the
interaction of magnetic materials can cause
distortion of the colors on your TV screen. Magnetic
storage media (such as floppy discs and tape or video
cassettes) should also not be kept close to this
speaker system.
For the installer
· Give adequate consideration to the location of
installation before the setup of this speaker system.
· Check the walls/ceiling to see if they are strong
enough to withstand the weight of the speaker
· Installation is possible on walls from 16 mm (5/8 in.)
to 25 mm (1 in.) thick.
· Check the walls/ceiling to confirm there is no wiring,
plumbing, beams, studs or air conditioning systems
that may interfere with installation.
· Pioneer disclaims any liability whatsoever for
damage resulting from assembly, improper
mounting, insufficient reinforcement, misuse of the
product, acts of nature, etc.

Painting the speakers
While the speaker and grille can be painted after it is
installed, painting it beforehand is much easier.
It is recommended to use spray paint, as brushed paint
may clog the holes in the grille and reduce the sound
quality significantly.
Remove the fabric scrim from the inside of the
Carefully peel off the fabric scrim and lay it down flat so
as not to get it wrinkled.
Use the supplied paint mask to cover the speaker.
If you don't have the paint mask, use paper and masking
Paint the speaker and grille the desired color.
As previously mentioned, it is strongly recommended
that you paint before installation and that you use spray
After the speaker and grille have dried completely,
remove the paint mask and carefully replace the fabric
scrim on the back of the grille.
Before installing
· Before installing the speakers, run the speaker
cables to the installation location.
· To maximize sound quality, choose the correct
speaker gauge cables from the table below.
If the resistance of the speaker cable is too high, the
signal will be attenuated and the speakers' frequency
response will be degraded.
How to install
Make sure you have read and understood all the
information above, For the installer on page 3 and Before
installing above.
Once you have decided on the installation location,
prepare the supplied template.
Cut out the inside of the template along the dotted line
and discard the inner section.
Attach the template (outer section) to the wall/
ceiling using tape.
Make sure the template is aligned properly.
Trace a line onto the wall/ceiling, following the
inner perimeter of the template.
Cut a hole where you have drawn the outline.
Be careful when cutting the hole, and use a proper
cutting tool.
Pull the speaker cable through the hole that has
been opened.
Be careful not to apply to much force when pulling on the
speaker cable or bend the cable at sharp angles.
Connect the cable wire to the speaker as shown
When connecting the speakers, be careful not to touch
the diaphragms of the drivers.
· After connecting the wires, pull lightly on them to
make sure that the ends of the wires are securely
connected to the terminals. Poor connections can
create noise and interruptions in the sound.

· If the wires are pulled out of the terminal posts and
the conductors come into contact with each other or
surrounding devices, an excessive additional load
may be placed on the amplifier. This may cause the
amplifier to stop functioning, and may even cause it
· Be careful to observe the correct polarity of the
connections between the cables and the speaker. If
the polarity (+, ­) of one of the speakers (left or right)
is reversed the stereo image will be severely
Where available, use the eye bolt located on the
back of the speaker system and attach a reinforced
wire, such as stainless steel wire rope, to the studs or
beams of the walls/ceiling.
· It is strongly recommended that you take double safe
precautions to prevent the speaker from falling by
· Put the reinforced wire through the eye bolt and
attach to the studs or beams. Make sure the stud/
beam that you are attaching it to is strong enough to
support the weight of the speaker system.
Place sound-absorbing material (such as fiberglass)
around the speakers as necessary to improve sound
Use only sound-absorbing materials that comply with
regional safety regulations.
Place the speaker into the hole you have cut.
Make sure the rotating clamps are turned inward.
· A Phillips screwdriver is required for loosening them.
· When using electric screwdrivers, first find out the
minimum torque required for the installation of the
speaker system. Begin by setting the electric
screwdriver to its minimum torque and gradually
raise the torque until the screw starts to rotate. Check
what torque setting you are on at this point (this will
be the minimum torque required for the setup). After
confirming the torque, return the rotating clamps
toward the inside by reversing the direction of
rotation of the screws. When doing this, take care
that the screws do not come all the way out.
10 Attach the speaker frame to the wall/ceiling, and
tighten the screws lightly (temporary attachment).
At this point the rotating clamp will rotate so that the
rotating clamp and frame are clamped on to the wall/
Gently try pulling the speaker forward and check that all
of the rotating clamps have rotated outwards and are
lightly clamping to the wall/ceiling.
11 Tighten the screws firmly using no more than the
maximum torque specified.
Allowable maximum torque: 1.0 N
· Screwing them in too tightly could break the rotating
clamps, twist the frames, damage the walls/ceilings
and make it difficult to attach the grille.
12 Make sure that the screws are not crooked and that
there is no gap between the wall/ceiling and frame.
13 Adjust the setting of the treble control as
· The standard setting is 0.
· The treble switch located in the front of the speaker
has two positions to choose from, +/0.
These speaker terminals carry
voltage. To prevent the risk of electric shock when
connecting or disconnecting the speaker cables,
disconnect the power cord before touching any
uninsulated parts.
