General Tips
Depending on the size and weight of your subwoofer, it is a good idea for two people to unpack it.
First take out the accessory pack, which is located in a smaller box inside the main box. This pack
contains the feet that are important for the operaon of your subwoofers and the required parts.
Your subwoofer should reach a temperature that is approximately equivalent to room temperature
before you connect it to the HiFi system and/or put it into operaon. If you do not let your
subwoofer reach this temperature, this may result in condensaon that may damage the electronics.
This parcular instrucon predominately refers to the winter months in case the loudspeakers were
previously stored in a cold room.
Maintenance
Our loudspeakers and subwoofers are coated in high-quality veneers or high-gloss lacquers. You
should avoid using chemical cleaning agents because these may aack the loudspeaker surfaces and
make them go ma. As a rule, a ne, so and damp cloth is all that you need to clean the surfaces.
Please ensure that you unplug your subwoofer before cleaning it. If a cleaning agent is required,
use this to dampen the cloth and do not directly apply it to the surface. It is best if you test the
suitability of the cleaning agent on a less visible part of the cabinet. Please make sure that no liquid
spills into the interior of your subwoofer. The driver does not normally need to be cleaned. Do not
expose the loudspeaker to direct sunlight. The surfaces are sensive to ultraviolet light and may
fade. The device normally does not need to be serviced. If you think that it does need to be serviced,
please contact your authorised AUDIO PHYSIC dealer.
Burning In Your Subwoofer
The LUNA driver is technically tested and burnt in prior to assembly. Your subwoofer will therefore
reach its full sound potenal aer a burn-in period of as lile as approx. 15 hours of operaon. We
recommend that you readjust the basic sengs of your subwoofer aer this burn-in period, in
parcular due to the fact that you will become more aware of your subwoofer aer a certain period
of playing me and it is therefore worth adjusng the subwoofer volume where necessary.
Stray Magnec Fields
The magnec eld created by the main magnet of the woofer may to some extent have an eect
outside of the loudspeaker. This stray magnec eld may interfere with other devices, parcularly
televisions and monitors with cathode ray tubes (not LCD or plasma televisions), for example
by causing changes in colour in the picture. We recommend that you place your subwoofer
approximately half a metre away from such devices (and also from magnet tapes, video cassees,
credit cards with magnec stripes, etc.).
Where possible, please retain the loudspeaker packaging. You can then securely transport your
subwoofer if you move house.

English High End Series
Safety Instrucons
1. Only use your subwoofer in dry rooms. If any liquids get into your subwoofer, immediately unplug
it and switch o any devices connected to it, for example ampliers, receivers or mul-channel
decoders.
For your safety, take your subwoofer to a specialist, at best an authorised AUDIO PHYSIC dealer,
to be checked.
2. Only use your subwoofer on a stable and level surface.
3. If your subwoofer has been exposed to a cold environment over a long period of me, please
wait unl it has reached room temperature in order to avoid condensaon, which may develop
in the case of sudden and large dierences in temperature and damage the electronics.
4. If you go away or do not plan to use your subwoofer over a long period of me, disconnect it by
unplugging it.
5. Do not leave your subwoofer unaended when in use.
6. Keep your subwoofer, especially the connecon terminals, out of reach of small children.
7. If you want to clean the surfaces of your subwoofer, please switch it o before doing so. Before
switching it back on, please ensure that there is no moisture on the connecon terminals and
that the terminals are securely connected.
8. Your subwoofer should only be opened and, where necessary, repaired by an authorised
AUDIO PHYSIC dealer. Any repairs to or work on your subwoofer that are not carried out by
an authorised AUDIO PHYSIC dealer shall result in a voided warranty. In the case of funconal
problems that cannot be solved or suspected damage to your subwoofer, unplug the device
and take it to your AUDIO PHYSIC dealer to be checked.
Unpacking and Assembly
1. Carefully open the packaging where it has been taped up.
2. Remove the accessory pack from the box.
3. Carefully remove the loudspeaker, together with its protecve foam pads, from the box. It is
ideal if two people carry out this step. Make sure that you do not break o the connecon
terminals or controls when removing and handling the loudspeaker.
4. Now remove the top foam cover and carefully slide down the protecve foil.
5. Stand the subwoofer upside down, preferably on a so surface (carpet or a thick towel) so that
the surface of the cabinet does not get scratched.
6. Screw the spikes supplied with your subwoofer into the threaded inserts in the base and use the
lock nuts to x them in place.
7. Stand your subwoofer the right way up again. Now follow the recommendaons for seng up
your subwoofer in the following chapter.
If you want to further increase the precision and sonic depth of your subwoofer’s
bass response, try out our high-quality VC feet (for example the VCF II M8 feet in
the image on the right). The “Vibraon Control“ feet are not only an alternave
to spikes for high-quality ooring, but also reduce the transmission of vibraons
between the loudspeaker and the oor. The result is an audible improvement to
the device’s realisc sound reproducon. For more informaon and advice,
please contact your dealer.

High End Series English
Seng Up Your Subwoofer
The fact that a subwoofer only reproduces the lowest frequency band means that a number of dierent
setups are possible in your room. It can, for example be placed by a wall, in a corner or in a free-standing
posion. The acousc rules that apply to other loudspeakers also apply to subwoofers, meaning that the
closer your subwoofer is to a wall or corner, the larger or smaller the increase in lower tones will be. You
can, however, use the electronics of the LUNA to compensate for these inuences in order to achieve
opmal results in all posions. You can nd out more about this issue in the chapter “Adjusng Your
Subwoofer”. There are, however, some posions that are parcularly suited to your subwoofer and
make the setup process easier for you.
1. Your subwoofer should generally be placed on a stable and level surface. Unscrew the spikes
that you previously aached to your subwoofer unl the device is level and all spikes are rmly
set on the ground. The spirit level enclosed with your subwoofer will help you to ensure that it is
exactly level. Once you have posioned your subwoofer, use the lock nuts to again ghten the
spikes. It is important that your subwoofer is level because depending on the bass depth and
volume, large forces act on the device when it is in operaon. If your subwoofer is not in a level
posion and on a solid surface, it may move out of posion due to an unbalanced distribuon of
force and strong vibraons.
2. The loudspeakers and subwoofer should not be placed directly next to each other. This may lead to
unwanted interacons between the devices, for example the loudspeakers causing each other to
resonate. A distance of around 50 cenmetres between the devices largely prevents these eects.
7
A handy helper: The enclosed spirit
level will help you to ensure that
your subwoofer is in a level posion.
50 cm

Placing your subwoofer in the corner of the
room results in a natural bass reinforcement of
around 9 dB
3. If it is possible to posion your subwoofer between the main loudspeakers, it should not be
placed exactly in the middle between the side walls. An ideal posion for your subwoofer is
on an imaginary straight line between the loudspeakers. This will simplify the setup process of
the subwoofer’s phase (please refer to the chapter “Setup”).
4. Depending on how close your subwoofer is to the walls, placing it in the corner of the room
will result in a broad bass reinforcement of up to 9 decibels. You can use the LUNA’s control
electronics to compensate for this reinforcement.
5. a. If you posion your subwoofer by a side wall or the back wall, be sure to choose a crossover
frequency that is as low as possible. This is parcularly relevant in the case of large rooms.
5. b. If you only want to use your subwoofer via the LFE channel of a surround system, you can place
your subwoofer by the wall or in a corner opposite the main loudspeakers without any problems
if you choose a crossover frequency on the receiver that is as low as possible.
If you choose to use this setup opon, the
crossover frequency should not exceed 80 Hertz.
This is parcularly relevant in the case of large
rooms.
English High End Series
8
Where possible, a rao of 1/3 to 2/3 to the side
walls is ideal - see point 7.
Your subwoofer should not be posioned exactly
in the middle.

6. Posioning your subwoofer by a side wall in a one-third to two-thirds rao is highly recommended
in terms of acouscs if, where applicable, your subwoofer cannot be placed between or next to
the front loudspeakers for opcal or spaal reasons.
7. In rooms in which the lengths of the side walls and the distance between the oor and the ceiling
are almost idencal, your subwoofer should not be placed in a corner because this may result in
parcularly strong room modes that disturb the sound reproducon.
8. If you decide to use two subwoofers, we recommend that you place them in symmetrical posions
to an imaginary axis extending from the listening posion to the central point between the two
main loudspeakers. This will result in a parcularly homogenous involvement of the room.
9. The sound of a system consisng of passive loudspeakers and an acve subwoofer can achieve
beer contours and more aenon to detail when your subwoofer is placed around 30 cenmetres
above the oor. When deciding whether or not to use such a setup, you should weigh up this
improved musicality against the opcal consequences of such posioning. This setup up is,
however, only successful when your subwoofer can be placed in a fully secure posion in which it
will not wobble at all.

Connecng Your Subwoofer
Please switch o all equipment in your HiFi system before you connect your subwoofer. Depending on
how you want to use your subwoofer, for example in a stereo or surround sound system, there are a
number of dierent possibilies when it comes to connecng your subwoofer to your system.
Operang Your Subwoofer in a Stereo Conguraon
You can integrate your subwoofer into your stereo music system in a variety of ways. If you have a com-
binaon consisng of a preamplier and a power amplier with a free „pre-out“ on the preamplier,
you can use this to connect your subwoofer. This also applies to integrated ampliers or receivers that
have an unused pre-out connector. Use an RCA cable of a suitable length to connect the “pre-out” jacks
to the LUNA’s “low level input”. “Record-out jacks” are not suitable for this purpose.
AUDIO PHYSIC recommends that you use the “high level input” to connect your subwoofer.
1) Connecng your subwoofer with an RCA cable:
2) Connecng your subwoofer with a loudspeaker cable:
You can also control your LUNA by using a second loudspeaker output on your amplier. To do so, you
need to connect the loudspeaker outputs, normally marked as “B”, of your integrated or power amplier
with the loudspeaker terminals on your subwoofer. Depending on the setup of your system, you can also
connect your subwoofer with cables from the loudspeakers in order to save cable. Loudspeakers mostly
accept cables with spades and banana plugs, meaning that this connecon method can be used without
any problems. Connect the cable from the le loudspeaker with the le “high level input“ of your LUNA
and connect the right channel with the right input accordingly.
If you hear a clear humming noise once you have acvated your subwoofer aer connecng it using this
method, it is very likely that this is due to a dierence in the ground potenals. You can nd out how to
simply recfy this problem on the following page.

High End Series English
Surround Sound Operaon
There are also two potenal connecon methods that can be used to connect your subwoofer with the
receiver in a surround sound system. Under no circumstances should you use both methods at the same
me to connect your subwoofer.
1) Connecng your subwoofer with an RCA cable:
To use this method, connect a suitably long RCA cable to the LFE RCA output of your surround sound
receiver and then connect this to the LFE input on your subwoofer. You only need to use one connecon
cable (mono) because LFE is an individual and autonomous sound channel. You can, however, also
addionally transmit sound informaon from the stereo channels from your subwoofer. For more
informaon about this possibility, please consult the operaon manual of your receiver.
2) Connecng your subwoofer with a loudspeaker cable:
If you have a surround sound receiver with a loudspeaker connecon terminal for the LFE channel, you
can also use a loudspeaker cable to connect your subwoofer. To do so, connect the LFE loudspeaker output
of your receiver to the right or le loudspeaker input of the LUNA.
A Humming Noise when in Operaon Using the High Level Input
Some conguraons may cause you to hear a deep low-frequency humming noise aer you turn on your
subwoofer. This noise normally does not indicate a technical problem with your subwoofer. You can recfy
this humming noise by using the RCA cable supplied with your AUDIO PHYSIC subwoofer. This cable only
establishes a connecon using the ground wire. Connect this cable to one of the free RCA jacks on your
subwoofer and to any free RCA jack on your amplier or receiver in order to remove the humming noise.

English High End Series
Seng Up Your Subwoofer
1. Acvang Your Subwoofer
Use the supplied power cable to connect your subwoofer to a
mains socket. Turn on the power switch on the back of your
subwoofer (marked with an arrow in the image on the right).
The indicator light next to the operang switch will then light up.
Move the operang switch to the “ON” posion. You should use
music that you know well for the next setup steps. Pieces of music
involving a singing voice accompanied by only a few natural
instruments are parcularly suitable.
2. Using the Controls to Adjust Your Subwoofer
You can nd the controls that you can use to opmally integrate your subwoofer into your HiFi or
surround sound system on the connecon terminal on the back of the LUNA.
3. Operang Your Subwoofer in a Surround sound System Using LFE
If you choose to use the LFE output of your receiver or surround sound processor to control your LUNA,
please set up the crossover frequency on your receiver (using the setup menu).
12
Volume: The LUNA has its
own volume control that
can be used to adjust the
volume of the subwoofer
in the system.
Phase switch: You can use this switch to choose
between the 0° and 180° sengs in order to
adapt the LUNA to suit your front loudspeakers.
Indicator light: This light shines green when the
subwoofer is in operaon and red when it is in
standby.
Crossover frequency: You can use this control knob
to select the maximum frequency that the subwoofer
should deliver between a 50 and 150 Hertz.
Operang switch: You can use this switch to acvate the LUNA and to disconnect it from the power supply
if you do not plan to use it for a long me. When the switch is set to the middle posion marked “AUTO”,
the subwoofer will enter into standby mode aer around 20 minutes when there is no signal

High End Series English
4. Seng Up the Phase (Stereo/Surround Sound)
If you choose to use the LFE output of your receiver or surround sound processor to control your LUNA,
the phase can normally be adjusted via your receiver (using the setup menu). If you want to adjust the
phase on your LUNA, you can use the same process as that used for stereo operaon.
To correctly set up the phase, rst turn the control dial for the crossover frequency to the maximum
value (150 Hertz). Select a medium volume for the LUNA; we recommend that you turn the control knob
to the central line.
Step 1: Seng the crossover frequency control knob to maximum and volume control knob to a central posion
Step 2: Now start to play your music. Pieces of music with a large number of low frequency tones are
parcularly suitable for establishing the phase. While your music is playing, use the phase switch
to change the phase seng from 0° to 180° and back several mes. The seng at which deep
tones can be heard louder in the listening posion is correct.
You have now idened the correct seng and can adjust the crossover frequency. This step does not
apply if you have chosen to operate your subwoofer using the LFE input.
5. Seng Up the Crossover Frequency and Volume
To idenfy the correct crossover frequency between your subwoofer and front loudspeakers, you
need to adjust the LUNA’S reproducon volume to suit your other loudspeakers. If you found the
bass reproducon in the previous step 2 too loud, use the volume knob on the LUNA control panel
to turn down the volume of your subwoofer.
Step 1: Seng the control knob for the crossover posion to minimum

posion.

English High End Series
Now start to play the music again. For this step, it is best to use a piece of music involving acousc
instruments, ideally a double bass and a male voice (bass or baritone). The song “Fever“ by Elvis Presley,
for example, is parcularly suitable for this setup process and can be found in many music collecons. The
track can also be accessed on one of a number of dierent websites if you have the opportunity to do so.
Step 2: Slowly turn the crossover frequency control knob and increase the crossover frequency
Please concentrate on the voice reproducon. Voices will most probably sound thin or cool with the
current seng at the lowest crossover frequency. Now increase the crossover frequency in small
increments unl the voices sound natural and full bodied. If you can clearly hear that the voices are
coming from the direcon of the subwoofer, this is a sign that the crossover frequency seng is too
high. When carrying out this procedure, please also pay aenon to the bass reproducon. If the bass
tones start to sound inated and sluggish at a certain point, reduce the crossover frequency somewhat
unl the sound reproducon is balanced. In this case, you may have to slightly turn the volume of the
LUNA back up.
Step 3: Finely adjusting the volume
If you can clearly hear the subwoofer, turn down the volume at this point until the sound reproduction of
the subwoofer no longer clearly stands out from that of the right and left loudspeakers.
Step 4: Finely adjusting the crossover frequency

For opmal adjustment, AUDIO PHYSIC recommends that you carry out steps 3 and 4 with a variety of
dierent pieces of music and then repeat the adjustment a few days later in order to ensure that you
have idened the suitable crossover frequency and correctly completed all adjustments.

Troubleshoong Soluons for Funconal Problems
Below you can nd some ps on how to deal with certain disturbances that may occur when using your LUNA.
• You cannot switch on the LUNA. / The indicator lamp does not light up.
Possible causes: • The LUNA is not connected to the power supply.
• The mains fuse is damaged.
Soluon: • Check the power cable and the plug. Try using another plug socket where
necessary.
• Replace the mains fuse. Please ensure that you unplug the power cable
before doing so!
• There is no sound despite the fact that the subwoofer is acvated.
Possible causes: • The polarity of a channel has been inverted if the high level input is being
used.
• The input cables are not connected or are damaged.
• The electronics have entered into standby mode for safety reasons due to
overheang.
Soluon: • Ensure that the cable is connected with the correct polarity.
• Please check the cable.
• Switch o your LUNA and wait unl it has cooled down.
• You can hear a humming noise aer you turn on your subwoofer (in the case of cables connected using
the high level input).
Possible cause: • There are dierent ground potenals between the components.
Soluon: • Use the RCA cable (that only has a ground contact) supplied with your
subwoofer to connect one of the RCA jacks (low level input/LFE) of your
subwoofer with any free RCA jack on your amplier or receiver.
