Thank you for purchasing this Sunfire
True Subwoofer EQ Solitaire. We hope
you enjoy it and the music it makes as
much as we have enjoyed creating it for
you.
The big breakthrough features of
the subwoofer are its uncanny track-
ing downconverter, its long throw, high
back-electromotive force driver, and its
fully automatic room equalizer. Taken
together, they provide this subwoofer with
as much bass as you could get from sev-
eral 15 inch drivers mounted in a cabinet
the size of a small refrigerator.
Introduction
Care
To maintain the speaker cabinet’s fin-
ish, first unplug the power cord and then
use a soft cloth to clean the surfaces.
If your Sunfire Subwoofer needs ser-
vicing, please read the Troubleshooting
section on page 21. If a problem still
persists, contact your nearest authorized

Your Sunfire True Subwoofer EQ Soli-
tiare is designed to give you the best pos-
sible low-frequency sound quality for your
Home Theater experience. It incorporates
a tremendously powerful built-in amplifier
and a single long-throw driver to produce
tight, floor-rumbling, denture-rattling bass
that you can feel as well as hear.
The subwoofer is available in two ver-
sions, and this manual covers both:
Solitaire 12 is a 13 inch cube, with an
output greater than 113 dB peak
SPL, 16 Hz to 100 Hz.
Solitaire 10 is an 11 inch cube, with an
output greater than 107 dB peak
SPL, 18 Hz to 100 Hz.
The subwoofer has an automatic
equalization system which will tailor the
subwoofer output to compensate for
any room effects. It also has a manual
equalization mode. An Equalizer Authority
control allows you to adjust the amount
of automatic equalization, and overide it
if required.
The subwoofer has an adjustable high
cut filter and a choice of speaker-level
or line-level inputs for easy incorporation
into existing systems, or as part of a
subwoofer/satellite speaker combination.
Controls for adjusting the volume,
crossover frequency and phase, allow
the subwoofer to be perfectly matched
to any listening environment and audio
components.
The Driver
To have lots of bass requires moving
lots of air. Your Sunfire Subwoofer incor-
porates a driver which can move back
and forth approximately five times more
than a normal subwoofer. This gives it a
lot of air moving capacity which allows for
majestic bass performance.
The Amplifier
The large movement range of the
driver creates greater air pressure inside
the box than a conventional subwoofer.
Therefore, the drive amplifier must be
much more powerful than an ordinary
subwoofer amplifier. In fact, it has to be
so powerful, it is almost hard to believe.
The power amplifier within the Solitaire
12 Subwoofer is capable of delivering
over 1,500 watts into a 3.3 ohm resistor
(the driver voice coil resistance). The
Solitaire 10 is capable of delivering 1,250
watts. When the same full output is ap-
plied to the driver, however, the enor-
mous back-electromotive force generated
as a consequence of its large motion and
giant magnet, causes the current flow to
be much less than if it were a 3.3 ohm
resistor. It is this singular property of the
driver that allows the subwoofer to be ap-
proximately ten times more efficient than
a subwoofer this size would normally be.
A compressor circuit kicks in automati-
cally if the input signal level reaches a
level that would overload the driver. This
maintains a ceiling on the output without
clipping. If the input signal is driven even
further, a ‘soft clipping’ circuit is enabled.
This allows the subwoofer to put more
sound into the room to satiate the power
hungry user, but without distortion or
damage to the subwoofer. Thus, for ex-
plosive scenes in movies, this produces
extremely high sound pressure levels
(SPL) in your room without the drivers
banging against the mechanical stops.

sign, please call us or view our website:

Overview

65SERgS-ANUAL
1. Volume
This control lets you match the output
level of the subwoofer to the level
of your satellite/main speakers. The
subwoofer output will increase as this
control is rotated clockwise. When you
have just installed your system, turn
this down first before turning on your
subwoofer. This will prevent any loud
surprises.
2. Crossover Frequency
This controls the high frequency cutoff
point. With the control set to the 100
Hz mark, the subwoofer will reproduce
frequencies up to 100 Hz. If the control
is set fully clockwise, the crossover is
bypassed and the subwoofer will re-
produce a wide frequency range. With
the control fully counter-clockwise the
subwoofer reproduces a narrow range,
up to 30 Hz.
Rotate the control until the bass sounds
natural. If the mid-bass sounds natural
but you want more low bass, turn this
control down a little, then turn the
Volume control up by about the same
amount. This increases the low-bass
output while leaving the mid-bass
output the same.
3. Phase Control
This control changes the relative phase
of the subwoofer with respect to your
other speakers. Use this control to help
blend the subwoofer with the rest of
your system. This is accomplished by
adjusting the control in small incre-
ments as you listen for the most bass
at your listening position. As a final trim,
readjust the Crossover Frequency and
Volume controls after the Phase has
been set.
4. Trigger Inputs
These two inputs can be used to auto-
matically turn on the subwoofer. To do
this, connect 12 VDC to either of these
terminals. Some Home Theater pre-
amplifiers, such as the Sunfire Theater
Grand series, have matching 12 VDC
Trigger outputs. When they are turned
on, the subwoofer will turn on.
5. Outputs
Line level high-pass output signals
are available at these jacks. These
outputs are active whenever a signal
is hooked up to the line level inputs
of the subwoofer. This crossover is a

passive network with a fixed crossover
frequency of 70 Hz and a 6 dB per
octave slope.
We recommend using this high-pass
function with main/satellite speakers
that are small and not designed to
reproduce low frequencies. If your main
speakers are capable of operating full
range, then you will not need to use the
high-pass function.
To use the high-pass outputs, connect
the preamp outs on your preamp/
receiver to the subwoofer’s line level in-
puts using good quality RCA type patch
cords. Then connect a second patch
cord from the subwoofer’s outputs to
the inputs of your main amplifier. This
will allow your main speakers to oper-
ate at frequencies above 70 Hz and the
subwoofer to operate at frequencies
below 70 Hz (see page 16).
6. Line Level Inputs
Connect these unbalanced inputs with
RCA type patch cords to the line level
outputs of your receiver or preamp.
If your preamplifier or receiver has a
single sub/LFE output, connect it to
the subwoofer’s left input jack (see
page 14). There is no need to use the
subwoofer’s right input jack.
If you want to run your main/satellite
speakers full range, use a “Y” adapter
at the preamplifier outputs (see page
15). In this way, you can send the
preamplifier’s output signal to your
main amplifier and to the subwoofer at
the same time.
7. Balanced (XLR) Input
Use this balanced input to connect
to the balanced line-level output of a
Home Theater preamplifier or other
source. Balanced connections offer
superior noise cancellation over unbal-
anced connections, so if your preamp
has an XLR subwoofer output, we
recommend using it.
8. Speaker Level Inputs
Under normal conditions, the preferred
connection is through the line level
inputs. If this is difficult or not possible
in your system, then you can use the
speaker level inputs. Also, if you expe-
rience excessive noise or hum with the
line level inputs, often a simple change
to the speaker level inputs will result in
a lower background noise level.
Connect the speaker level inputs to the
speaker-level outputs of your amplifier
or receiver using speaker wire. The
binding posts can accept bare wire,
banana, dual-banana or spade con-
nections.
Your amplifier or receiver MUST
have common grounded outputs,
or it will be damaged if connected
to the subwoofer’s speaker level
inputs.
9. Line Fuse
The subwoofer is supplied with a con-
servative slow-blow type fuse to protect
the electronics.
Always unplug the power cord
before inspecting or changing the
fuse. Never use a fuse with a larg-
er current rating than shown on the
markings next to the fuseholder.
10. IEC Linecord socket
The subwoofer comes with a detach-
able linecord which connects here.
US (120 VAC) MODEL: Connect
the linecord to the subwoofer before
connecting the other end to an 120
Volt, 60 Hz AC outlet. The outlet must
have a circuit rating of 8 amps or more
(a typical home circuit is rated at 15
amps).
Never plug the US (120 VAC)
Model subwoofer directly into
220-240 Volts AC as this will cause
catastrophic circuit failure.

85SERgS-ANUAL
Control Panel Features continued
EURO (230 VAC) MODEL: Connect
the linecord to the subwoofer before
connecting the other end to a 230 Volt,
50/60 Hz AC outlet. The outlet must
have a circuit rating of 8 amps or more.
Never plug the Euro (230 VAC)
model subwoofer directly into 120-
130 Volts AC.
11. Power Switch
The power switch is a CE requirement
for international shipments. Leave it
switched on at all times for normal
operation.
After a period of inactivity (i.e. with
no input signal), the subwoofer will
automatically turn itself to Standby
mode, where it is effectively off. It can
however, turn back on automatically
when an input signal is applied, if a
12 VDC trigger voltage is applied to the
Trigger inputs, or if the Start button is
pressed.
12.Start button
Press this once to enter the Auto EQ
mode (if the sub is out of Standby
mode). Press and hold down for
several seconds to enter the Manual
EQ mode. See page 12 for more
details on this and the following EQ
controls.
13.Microphone Input
This is where you plug in the supplied
linear measurement microphone when
you want to use the Auto EQ mode.
14.LED display
These LEDs are used during the Auto
EQ and Manual EQ procedures.
15.Equalizer Authority
This control's primary purpose is to
adjust the EQ Authority. During normal
listening, you can adjust the overall EQ
from none (ccw, 0%), to fully equalized
(cw, 100%). For example, if your first
band has a 6 dB boost, setting this
control to 50% would make it boost
only 3 dB.
This control is also used during the
Manual EQ mode to adjust each of the
four internal EQ bands, and allow you
to add "color" to the sound as desired.

Installation
Observe the following general precau-
tions and read the safety instructions on
pages 2 and 3 before using your Sunfire
Subwoofer.
• Never open the cabinet or remove
the metal control panel as this
might result in an electrical shock to
you, or damage to the unit.
• Protect it from prolonged exposure
to direct sunlight and other direct
sources of heat, such as heating
vents and radiators.
• To prevent fire or shock, do not
expose the unit to rain or moisture.
If fluid or a foreign object should
enter the unit, immediately turn off
the power and contact your Sunfire
Dealer.
• Avoid excessive exposure to
extreme cold or dust.
• Do not place heavy objects on top
of the unit.
• Do not place the subwoofer with its
control panel against the floor.
• If you wish to place your subwoofer
so the drivers face the floor and
ceiling, thereby moving up and
down, use at least 1-1/2 inch high
spikes or feet for support. They
may be attached either with screws
or self-stick backing. This arrange-
ment will impart substantial house
and floor shaking motion.
• Four extra heavy, shock absorbing
rubber mounting feet have been
included. If your subwoofer tends
to wander about slightly while in
use, place these feet just inside
the existing feet positions. These
shock absorbing mounts will let
the subwoofer rock freely, thereby
absorbing low frequency rocking
energy, allowing it to adhere solidly
to the floor.
• To move the subwoofer along the
floor, rotate it onto one edge onto a
plastic sheet or bag, and it will slide
along easier.
Heat rise
• Allow adequate ventilation around
the metal control panel of the
subwoofer.
• Do not let anything come into
contact with the panel and keep
at least two inches away from any
walls.
The metal control plate serves as the
amplifier heat sink and also as a conduit
to remove internal heat to the outside
and into the atmosphere. It can reach
temperatures of 60 degrees C, which
will feel hot to the touch, using nerves of
flesh and blood as temperature sen-
sors. As uncomfortable as it may feel, 60
degrees C cannot burn you, and in fact is
almost cool to copper, silicon, steel, and
aluminum, the materials from which your
subwoofer is constructed.
AC Power Considerations
Ensure that the unit is plugged into an
outlet capable of supplying the correct
voltage specified for your model.
Unplug your subwoofer’s power cord
from the electrical outlet if it will be left
unused for a long period of time.
Route the power-supply cord so it is not
likely to be walked on or pinched by items
placed upon or against it, especially at
plugs, convenience receptacles, and the
point where it exits from the unit.
Magnetic Fields
We recommend that you place your
subwoofer further than two feet away
from your TV, VCR, tape deck or com-
puter, so the speaker’s magnet won’t
distort the colors of your TV picture or
erase your video tapes, audio tapes or
computer discs.

10 5SERgS-ANUAL
Please consider the following when set-
ting up your new system :
• Before making or changing any
connections, ALWAYS make sure
that the subwoofer and your other
components are turned OFF. Also
turn down the volume control of the
subwoofer and your preamplifier or
receiver.
• This diagram shows all the low
power components sharing a power
strip which is connected to the same
outlet used by the amplifier.
• The subwoofer is connected to an
outlet on the same circuit breaker,
provided that the total system
current draw does not exceed the
breaker current rating.
• This arrangement will reduce the
possibility of an audible hum in your
system caused by a ground loop.
• Whenever possible, keep the
power cords away from the signal
cables or speaker wires to prevent
any hum or interference being
heard in the speakers.
• Choose reliable, high quality inter-
connect cables, also called patch
cords or RCA cables. They should
be fully shielded and as short as
possible for the job. The longest
cable in your system will likely be to
the subwoofer, so choose a good
quality brand.
• Some patch cords can be a very
tight fit and there is usually a
preferred method of getting them
off. Some have to be removed with
a twisting action. Be gentle or you
may damage the jacks of the sub-
woofer or your other components.
Speaker Level connections
• The subwoofer’s speaker level
inputs can accept speaker wires
with banana, dual-banana, bare
wire or spade terminals. If you have
banana type connectors on your
speaker wire, make sure that you
tighten the binding posts before
inserting.
• Make sure that the negative
speaker wires never touch the posi-
tive wires as this will short out and
possibly damage your amplifier or
receiver.
The subwoofer’s two negative
posts are joined internally (com-
mon-grounded). Your amplifier
must also be internally common-
grounded or you cannot use this
connection. Contact the manufac-
turer of your amplifier to make sure
its outputs are common grounded.

Placing your subwoofer in a corner
will produce optimum performance.
Experiment with at least two corners and
decide which is the best, or you can try
the following procedure:
1. Start by placing the subwoofer right
on the seat of your favorite couch
or easy chair. Take care to position
it so it is not likely to fall off. (This
method may seem a bit odd, but it
is based on principles of acoustic
physics.)
2. If you are using the subwoofer as
part of a Home Theater system,
you can either run a calibration
test (noise) signal through the
subwoofer, or simply plug the
analog outputs of a CD player di-
rectly into the subwoofer’s line level
inputs. Turn down the subwoofer's
volume level before turning on the
CD, then play some of your favorite
music samples with heavy bass.
3. Walk around the room, listening,
and crouch down low in all the
positions where you might be able
to place the subwoofer. Ideally your
ears would be where the sub would
be placed. Explain to the family
what you are doing, in case they
think you've flipped. Find the place
where the subwoofer's bass output
sounds the loudest.
4. Shut things down and install the
subwoofer in this position. Make
sure the control panel is not touch-
ing anything, and that it can receive
good ventilation.
Although low frequencies are non-di-
rectional, factors such as room reflec-
tions, standing waves, resonance and ab-
sorption will strongly affect your subwoof-
er’s performance. Moving the subwoofer
from one location to another can have a
major effect on the bass response.
Location
The Auto EQ mode will let you adjust
for the room effects, but you should find
the best location first.
Remember to keep the subwoofer
at least two or three feet away from
any TV screen, computer, VCR or
magnetic tapes and discs. This will
reduce the chance of the magnetic fields
upsetting the TV screen or erasing your
magnetic media.
Using Two Subwoofers
If you wish to use two subwoofers, the
sound output will double (an increase of
6 dB). Locate the subwoofers with one
in each corner and experiment with the
location and phase control to achieve the
best bass response.
Always drive each subwoofer through
the Left/Mon input even though you are
driving one subwoofer with a right chan-
nel drive and the other with a left channel
drive. If your preamplifier has a single
sub/LFE output, use a Y cable to split it
into two outputs.

Subwoofer performance is greatly af-
fected by the room in which it is situated,
and the positioning within the room. The
room effects will boost and cut the output
levels reaching your listening position.
This gives a "Room EQ" effect which can
often be far from wonderful.
The Sunfire True Sub EQ can automati-
cally adjust for the effects of Room EQ. It
measures the actual frequency response
using the supplied measurement micro-
phone. Then it automatically compen-
sates for peaks or dips and smooths out
the response.
For best results it is recommended that
the subwoofer crossover in your receiver
or processor be set to its maximum set-
ting (or “bypass”). This ensures that the
subwoofer will be properly matched to the
rest of the speakers in your system.
The following procedure will help you
start the automatic equalization:
Automatic EQ Mode
1. Install the True Sub EQ in the best loca-
tion you can find (see previous page).
2. The calibration must be done while the
listening room is quiet. Please turn off
any noisy machinery, including heating
or cooling systems during this process.
Have the kids play in the backyard and
give the dog a treat to have him stop
barking. A small amount of noise, such
as quiet talking or whispering, is OK.
Room Equalization (EQ) Procedure
3. Place the microphone in the listening
position (on the couch, for example),
pointing in the direction you’ll normally
be facing while listening to your system.
Only use the microphone supplied by
Sunfire.
4. Plug the microphone into the subwoof-
er's microphone jack.
5. Set these controls:
• Volume to 0 dB.
• Crossover to "Bypass."
• Phase to "Normal."
• Equalizer Authority to "Normal"
6. Turn on the subwoofer AC power switch
and press the Start button to go from
standby to play mode. The yellow LEDs
should light up. Press Start again, and
hold it a moment to start the calibration.
7. The subwoofer will generate a test tone
sweep, slowly increasing up the fre-
quency scale; the microphone will take
measurements of the sound arriving at
your listening position. The LEDs will
flash randomly for a while, then the pairs
will gradually glow constantly as each
band is measured. This sequence will
repeat twice until the measurements are
complete. The LEDs will all blink once
and stay on, and the test tones will stop.
If you find that the first test tone plays
louder and louder, and never leaves the
first band, then either the microphone is
too far away from the subwoofer, or it is
not plugged in correctly.
8. The procedure may take several
minutes. Do not make any loud noise
during this process, as it may affect the
accuracy and/or make it take longer.

5SERgS-ANUAL
9. The sub automatically calculates the
best equalization, based on the mea-
sured frequency response at your listen-
ing position. This will be saved, before
returning to the normal listening mode.
10. In normal listening, you can adjust the
overall effect of the saved EQ settings
with the Equalizer Authority control.
Normally you would turn it to 100% for
full equalization. You can turn it to 0%
to judge the effect of no equalization, or
vary it to suit your taste.
11. Repeat the Auto EQ procedure if you
change the location of the subwoofer, or
if you rearrange your furniture.
Manual EQ Mode
This mode allows you to manually
adjust the room equalization to suit your
taste. Some rooms may sound flat or life-
less without a touch of color to the sound.
The subwoofer has four EQ bands,
each represented by two yellow LEDs.
Each band is fixed in frequency and
bandwidth, but each can be adjusted in
volume level using the Equalizer Author-
ity control during the Manual equalization
mode.
This is similar to
having sliders on
a 4-band graphic
equalizer. except the
settings for each band
are stored digitally.
The subwoofer saves the setting of the
Equalizer Authority control for each band,
so adjusting it for one band does not alter
the adjustment for the other bands.
First, you should follow the Automatic
EQ procedure, so the subwoofer will
adjust for the room effects. Then follow
this manual procedure if you think the
equalization might still need a tweak:
1. Set these controls:
• Volume to 0 dB.
• Crossover to "Bypass."
• Phase to "Normal."
• Equalizer Authority to "50%"
2. Turn on the subwoofer AC power switch.
3. Press and hold down the Start button

System Configurations
The following pages show some typical
connections that you might make in your
installation. They show how the inputs
and outputs of the Sunfire Subwoofer
are connected to your preamplifier or
receiver.
If your preamplifier has a
subwoofer output (often labeled LFE
for Low Frequency Effects), it can be
connected to the subwoofer’s Left
(Mono) input as shown. This is the
simplest and recommended con-
nection. A receiver with a sub/LFE
output can be connected in the
same way.
The subwoofer will play the low
frequency range and the other
speakers will play the frequency
range delivered to them by your
amplifier.
If you have a Home
Theater preamplifier,
it may have an inde-
pendent subwoofer vol-
ume control. Make sure
this is correctly adjusted,
and that the Sunfire
Subwoofer’s crossover
frequency is set to 100
Hz. This is by no means
an iron-clad rule, rather it
is a good starting point.
(See the crossover fre-
quency control details on
page 6 and adjustments
on page 18).
You can set the subwoofer’s Vol-
ume control to 0 dB, and then use the
preamplifier’s subwoofer level control for
normal and routine adjustments.

If your preamplifier does not
have a sub/LFE output, you can
use “Y” cables to send its main
outputs to both the subwoofer and
your amplifier.
The subwoofer will play the low
frequency range and your front
speakers will play the full range.
Although bass is commonly dis-
tributed evenly between left and
right channels (L+R bass), movie
soundtracks often contain dif-
ferential (L-R) bass. The opening
scene in “Top Gun”, for example,
has loads of L-R bass infor-
mation. If this is not
preserved, the bass
in these scenes
sounds anemic. The
Sunfire Subwoofer
utilizes differential
gain on the left and
right inputs to retain
both the L+R and
L-R information.
Therefore, systems
which do not have a
dedicated sub/LFE
output should use
both the left and the
right inputs as shown, for the greatest
bass impact.
An alternative connection method
without using Y cables is shown on the
next page.
If your preamp/receiver has a dedi-
cated sub/LFE output, then only the Left
(Mono) input is used, as shown on the
previous page.

If you are using a preamplifier
which does not have a sub/LFE
output, you can send its left
and right front output into the
subwoofer’s Line Level inputs
and then connect the subwoof-
er’s High-Pass outputs to the
inputs of your amplifier.
The subwoofer will play
the low frequencies and your
amplifier and front speakers
will play the frequency range
above the subwoofer’s fixed
high-pass crossover point.
The signals coming
out of the subwoof-
er’s high-pass
outputs are not
affected by any of
the controls. They
are just a copy of
the signals going
in except that the
low bass is filtered
out. This uses
the subwoofer’s
passive crossover
network, rather than
the active network
and controls.
This is an excellent method if your
speakers are small satellites or mini-
monitors, and/or your power amplifier is
of limited power, such as a tube amp.

If you are using a receiver
which does not have a sub-
woofer output or line level
outputs (pre-outs), you can
connect its speaker outputs
to the subwoofer’s speaker-
level inputs. The front speakers
can still be connected to your
receiver.
The subwoofer’s internal
amplifier supplies the power to
reproduce the low frequency
range. It receives a sample of
the signal going to your front
speakers. (An insignificant frac-
tion of your receiver’s power is
transferred to the subwoofer).
There is no
need to use the
speaker level
inputs if you are
using a separate
amplifier and pre-
amplifier. Such
systems are
best connected
using the line level
inputs as shown in the previous
diagrams.
If you are using the line
level inputs and there is a
excessive amount of noise
or hum present, using the
speaker level inputs may yield a
lower background noise level.
Your receiver MUST have common
grounded outputs, or it will be dam-
aged if connected to the subwoof-
er’s speaker level inputs.

There are two main methods for adjust-
ing the level, crossover frequency and
phase of the Sunfire Subwoofer to match
a system:
• Bob Carver’s preferred method:
By listening and making the
adjustments to suit your taste.
• Laboratory method: By measuring
the output and adjusting for a flat
frequency response.
Excellent results can be obtained if you
make the adjustments based on simply
listening. This is Sunfire’s preferred meth-
od as it allows the system to be voiced
based on what sounds the best, whereas
laboratory-flat frequency response can
often be clinical and less than exciting.
The following procedure is for those
who prefer a more methodical and scien-
tific approach. This excerpt is from “The
Audio Critic,” issue 24, page 31, written
by contributing editor David Rich, and is
reprinted here with their kind permission.
You will need a test CD with low-fre-
quency warble tones, and a sound pres-
sure-level meter. The Radio Shack®SPL
meter will do fine, as will the Stereophile®
test CD.
“Step 1. Disconnect the subwoofer and
run the main speaker with a tone in its
passband (80-100Hz). Measure the level.
Step 2. Disconnect the main speaker
and reconnect the subwoofer. Set the
subwoofer to its highest crossover
frequency. Set the level control of the
subwoofer to give the same sound pres-
sure level with the same tone you used
in Step 1.
Step 3. With both the subwoofer and
the main speaker connected, measure
the level of the tones at the available
frequencies. Because the crossover
is set too high, you will have a peaked
response. Adjust the crossover control to
get the smoothest response.
Adjusting the controls
Step 4. Use the phase control to make
the response even smoother. It has its
biggest effect at the crossover frequency.
You can iterate between the crossover
and the phase controls. Keep your hands
off the level control! It was set correctly
in step 2.
Step 5. Listen to the subwoofer.
Resist all temptations to turn up the level
control. Play something with really deep
bass to confirm that your subwoofer is
working.”
