The SUB THREE Subwoofer System is the product of
extensive research into the qualities required for realistic
music and film sound reproduction. The SUB THREE's
engineering, construction, and materials far exceed
conventional industry standards and result in superior
performance and reliability.
The SUB THREE Subwoofer System consists of
one or more SUB THREE subwoofers and the
appropriate crossover. The SUB THREE uses three
eight-inch drivers, each with a massive 1.5 inch, four-
layer voice coil and a forty-ounce magnet structure. The
integral 300-watt amplifier does not current limit and has
ample power for the most demanding situations. The
amplifier's feed-forward error correction eliminates
response and phase variations that would
HOW THE SUB THREE WORKS
Conventionally powered subwoofers receive
their input signal directly from their crossover instead of
the main amplifier. The sonic signature of the main
amplifier that is an integral part of the sound you hear
from the full-range speakers is missing from the
subwoofer. This sonic discontinuity causes blending
problems as the system's sonic characteristics are
different above and below the subwoofer crossover
point. The SUB THREE Subwoofer System uses a
unique connection method that reduces the main
amplifier's current demands and leaves the main
amplifier in the signal path to the subwoofer. This
connection method insures

The SUB THREE Subwoofer System will interface
with most electronics, main speakers, and
environments. The EQ, crossover, and sensitivity
settings allow the SUB THREE's optimization to the
main amplifier's input specifications, the main speakers'
efficiency, and the listening room requirements. The
innovative Q control then allows you to tailor the bass
response's character to best suit your tastes and the
room characteristics. The SUB THREE's pleasing
appearance will enable it to visually complement your
main speakers and the decor of your home.

the main amplifier's characteristics, evident through the
full-range speakers, sonic continuity are maintained to the
deepest bass, but with the power and control of the SUB
THREE's internal 300-watt amplifier.
Like conventional subwoofers, the high-pass portion
of the SUB THREE's crossover is inserted into the signal
path just before the main power amplifier to roll off the
low-frequency response of the main amplifier and
speakers. The difference is that the SUB THREE does
not take its input from its crossover but from the main
amplifier in parallel with the main speakers. To
compensate for the low-frequency roll-off, the SUB

THREE's amplifier's response is contoured to restore
the low frequencies to the proper level induced by the
crossover. The SUB THREE's input Impedance is high
enough (over 100k ohms) that it has no discernible effect
on the main amplifier's output.
THE SUB THREE CROSSOVERS
Each SUB THREE subwoofer needs an M5-HP
crossover.
Mono OR Stereo Bass?
There are significant advantages to using two sub-
woofers. Summing the channels into a single subwoofer
reduces or cancels all the low-frequency information
containing phase differences between the channels.
Stereo subwoofers reproduce all of the bass information,
complete with the phase differences that help provide the
imaging and location clues we use to place people and
things at distinct points in the sound field. Stereo
subwoofers also lend themselves to natural placement
near the corners where the low-frequency room gain is
more linear and often desirable.
ADJUSTABLE SENSITIVITY, ROOM EQ, AND Q
FEATURES EXPLAINED
The sensitivity, room EQ, and Q controls on the
SUB THREE's input plate allow you to match the bass
level to the full-range speakers and tailor the
characteristics of the low frequencies.
The sensitivity control's label is in dB to initially
match to the main speaker's efficiency rating, the Q
control starting setting is "1", and 11-bands of EQ at
noon.
The Q control can then tailor the SUB THREE's low-
frequency response to compensate for room
characteristics and to best suit your sonic tastes. The Q
control is from 1 to10. Position 1 provides the tightest
bass and best transient response, while position 10
emulates a typical home theater subwoofer's peaked
response. The Q control effect on the SUB THREE's
frequency response is illustrated in the graph below. For
clarity, only positions 1, 5, 7, 9, and 10 are shown. (The
chart does not include the effects of low-frequency room
gain.)
When you want more of a
conventional home theater sound,
turning up the system's bass tone
control will provide the extra low-
frequency emphasis that is
desirable in many movies. If your
system does not have tone controls,
setting the SUB THREE's Q control
to a higher number will yield similar
results.
The 11 Band EQ adjusts your
SUB THREE precisely to the room
bass nodes to the sub's position.
Setup is explained in a later
section.

SUB THREE SYSTEM SETUP
PACKING LIST
The following components, accessories, and
documents come with each SUB THREE subwoofer:
1 SUB THREE subwoofer with an integral
amplifier.
1 Twenty-foot lengths of speaker cable.
2 Dual banana plugs.
3. Spikes with jam nuts. (3/8 x 16 thread)
1 Operation manual
1. Five-year warranty registration
1 Power Cord
SETTING THE M5-HP FOR YOUR SUB THREE
SYSTEM
When the M5-HP is used with the SUB THREE
series subwoofers, the sticker on the chassis cover
should be ignored because these settings are for 100 Hz
High Pass and the SUB THREE is designed for 80 Hz
High Pass. Set the switches according to the chart
below. An alternate crossover setup method is available
via our YouTube Channel on the website.
1. Remove the M5-HP cover and locate the
internal set of 8 dip switches. The exact type of
switch used may vary.
Single-Ended M5-HP Crossovers (RCA input and
output with eight-position switch) Set the Single-Ended
M5-HP to match the input impedance of the main
amplifier.
Balanced M5-HPB Crossovers (XLR input and output)
Set the Balanced M5-HP to match the impedance SUM of the
positive and negative legs of the main amplifier's input. (The
individual legs must each be one-half of the impedance sum.)
3. Turn on the switches listed for the value you found. The
numbered side is "ON." Slide and toggle type switches are
on when they are toward the numbers, and a rocker type
switch is on when it is depressed on the side of the numbers.
Some switches are labeled "OPEN" and "CLOSED." OPEN is
OFF, and CLOSED is ON.
4. Install the M5-HP into the signal path just before the
main amplifier. On receivers and integrated amps, install
the M5-HP between the "Pre Out" and "Main In" jacks.
CAUTION: The SUB THREE must be used
with a properly adjusted Vandersteen High
Pass Filter. If using an integrated, only those
with a pre out and amp in loop are useable

SUB CONNECTION
Do not install the spikes at this time. Without the
spikes, the SUB THREE can easily be pushed
across the carpet to try different locations. The SUB
THREE(s) should be placed on the same wall as the
main speakers with just a couple of inches of
clearance for amplifier ventilation.
Two 20-foot lengths of speaker cable and two dual
banana plugs are provided with each SUB THREE
for connection to the main amplifier. Attach a dual
banana to one end of each cable to plug into the
SUB THREE. Leave the cables full length so you
can try the sub in different positions for the SUB
THREEs once the Break-in period has elapsed.
With the M5-HP crossover installed in the signal
path just before the main amplifier, connect the SUB
THREE(s) in parallel with the main speakers, as
shown in the illustrations. With stereo subwoofers,
only one input on each subwoofer is connected. In
bi-wired systems, three sets of wires are attached to
the main amplifier. Use spade lugs on the amplifier
end of the wires going to the main speakers and
banana plugs on the subwoofer end of the
subwoofer wires. After the main speaker wires are
connected, insert the subwoofer's banana plugs into
the amplifier's binding posts.
If your amplifier has connections for two sets of
speakers (i.e., A & B), do not connect the main
speakers to one and the subwoofer to the other.
Often there are differences between the two sets of
outputs. Some systems may also benefit from
connecting the SUB THREE with the same cable
type as the main speakers.
All connections must be in the proper polarity. If one
of the SUB THREE's inputs is connected out-of-
phase from the other input in a mono subwoofer
system, the inputs will cancel. With stereo
subwoofers, connecting one subwoofer out-of-phase
from the other will seriously affect the amount and
quality of bass.
Once the crossover and cables are correctly
installed in the system, the subwoofer should be
plugged into a non-switched AC outlet. As it is
plugged in, the SUB THREE should produce a low-
frequency thump.
SUB PLACEMENT
While the SUB THREE(s) should be on the same
wall as the main speakers and close to the wall the
exact placement will probably depend as much on
practical as acoustic considerations. Placement
affects the subwoofer's sound, so you should try all
the placements that will work in your domestic
situation. Be flexible; it is only important that a single
subwoofer be centered when it is mated with small,
limited range main speakers. With full-range main
speakers, the subwoofer may work better in the
corner. In general, a subwoofer will sound fuller and
more powerful when it is in a corner and leaner
when it is and away from walls. The SUB THREE's
adjustable Q allows some compensation for these
effects and expands the placement options in most
rooms.
As you try different placements, you may also have
to readjust the SUB THREE's sensitivity and/or Q
setting to maintain the best balance with the main
speakers' considerations and redo the room EQ
settings outlined later in this manual.
SPECIAL INSTRUCTIONS FOR BI-AMPED
SYSTEMS
In horizontally bi-amped systems, install the M5-
HP crossover before the bass amplifier: Connect the
bass amplifier to the SUB THREE(s). In vertically bl-
amped systems, install the M5-HP before the channels
being used for bass. Connect the bass channels to the
SUB THREE(s).

Audio/Video CONSIDERATIONS
When a SUB THREE is used in an audio/video
system, the basic configuration is similar to a music
system. The crossover Is inserted into the signal
path just ahead of the main amplifier, and the SUB
THREE is connected to the amplifier in parallel with
the right and left main speakers.
With Separates (External Processor)
The crossover is inserted into the signal path
after the processor and just ahead of the main front
left and right amplifier. The surround processor
must be programmed to blend all the low frequencies
into the main front left and right channels rather than
routing them to the center channel or the processor's
subwoofer output. Information on configuring your
processor for these parameters is available in the
processor's manual or from its manufacturer.
WITH AN A/V RECEIVER
The crossover is inserted into the signal path
between the "Pre Out" and "Main In" jacks.
Without this connection option, the SUB THREE
cannot be used. The receiver must be programmed
to redirect the low- frequencies into the main front
left and right channels rather than routing them to
the center channel or the receiver's subwoofer
output. Information on configuring your receiver for
these parameters is available in the receiver's manual
or from its manufacturer.
DISCRETE MULTI-CHANNEL
Discrete multi-channel audio formats can use up to
four subwoofers. The best way to integrate
subwoofers into the system depends on how many
you use.
The following recommendations assume
that the LFE information is redistributed to the
right and left front channels.
The Number of System Subwoofers:
1 Subwoofer:
Connect the subwoofer to the left front
and right front channels.
2 Subwoofers:
Connect one subwoofer to the left front
channel and the other subwoofer to the right
front channel. Two subwoofers are a quantum
improvement over a single unit and preferable
in high-quality multi-channel systems.
Systems that have reached the level
where there are no significant advantages to
Improving the electronics or speakers can
benefit from adding two more subwoofers for
surround channels.
4 Subwoofers:
Left front, right front, left surround, and
right surround. (When the SUB THREE'S
are used with Vandersteen VSM surround
speakers, the crossover should be two
settings below the surround amplifier's
input impedance. This setting will avoid
interaction with the VSM series surround.
Like the main amplifier, the surround
amplifier will use the speaker's integral
high-pass filter.)
OPTIMIZING SETTINGS
POLARITY
The SUB THREE's polarity may need to be reversed
with some main speakers to provide the best
integration. To reverse the SUB THREE's polarity,
simply turn the banana plug(s) around to connect the
main amplifier to the subwoofer negative and the main
amplifier negative to the subwoofer positive.
SENSITIVITY
The SUB THREE's sensitivity control should initially be
set to match the approximate sensitivity of your main
speakers and then be fine-tuned per the instructions on
page 2. Adjustments to the Q control or polarity may be
needed when the sensitivity is changed.
LOW-FREQUENCY ROOM OPTIMIZATION AND
LEVEL
The eleven room compensation controls located on the
rear input plate help counter the amplitude and phase
effects of room nodes and anti-nodes and provide the
most linear low-frequency response at the listening
position. This disk is calibrated for the Radio Shack
analog SPL meter. Once the controls have been set for
a particular room, they do not need to be readjusted
unless the speaker placement and/or listening position
are significantly changed.
All discrete multi-channel formats have a Low-
Frequency Effects channel. Experience and
research have convinced us that these formats
sound much better when the processor is
programmed to redistribute the LFE information
to the right and left front channels. You should
check with your processor's manufacturer as to its
capabilities in this regard.
The following information assumes that the
break-in period has elapsed. Finalizing the
SUB THREE’s placement, sensitivity or Q
setting before the it is fully broken-in could
compromise the ultimate performance level.

TECHNICIAN’S ADJUSTMENT SECTION (A Video of this setup process is linked on our website and
on our YouTube channel. It is the same process as the Model Seven setup shown. Setup worksheets
are also available on the website)
Only a qualified technician or owner with an Analog Radio Shack S.P.L. Meter and matching test disc should
adjust the room compensation controls. This procedure can take several hours. PLEASE NOTE: If you are
calibrating a single SUB THREE you will only employ tracks 1-11 with the Preamp set to Mono. If you don’t
have a mono setting you will need a low-cost “Y” adaptor to drive both left and right channels simultaneously,
main speaker included.
The steady state test signal can cause the SUB THREE amplifier to run warm. This disk is calibrated to the
Radio Shack analog S.P.L. Meter. Owners take your time, it’s possible.
TECHNICIAN’S GUIDE TO ADJUSTING THE ROOM COMPENSATION AND LOW-FREQUENCY LEVEL
CONTROLS.
1. Set the S.P.L Meter at the listening position at ear height. Turn on the S.P.L. Meter to the 70dB scale, “C”
weighting, “Fast” response.
2. Insert test disc into a CD Player, set the volume on the preamp to a low level. CD automatically does left
first.
3. On the SUB THREE Amplifier set the low frequency contour control to minimum (#1) and verify that all
eleven room compensation band are set straight up (slot vertical). Set low frequency level to 0dB.
4. Play tracks nine through eleven and note on paper the meter readings for all three tracks. Adjust the
preamp volume up or down until these tracks average 70dB. Example: track nine 69dB, track ten 72dB and
track eleven 68dB. This is your reference volume do not adjust until this entire calibration is complete for both
speakers.
5.Play track one through eleven and adjust each band to 25 to 33% of the meter reading noted in step # 4.
Play tracks:

Note: Do not try to adjust every peak or dip all the way to 0 dB. Our studies have shown that adjusting all the
peak and dips to 0dB can cause a non-musical sound with audible equalization effects. Your Sub is now
properly compensated for the room.
6. To set Stereo SUBs play tracks twenty four through twenty six and note on paper the meter readings for
these tracks. Adjust the right SUB THREE Low Frequency Level Control up or down until these three tracks
average 70dB like the left channel. Save this last set of reading for use in step# 7.
7. Play tracks sixteen through twenty six and adjust the right speaker bands as in step# 5. Note: Occasionally
full adjustment of one or more of the bands will not adjust to the target value for the right or left SUBs, get it as
close as possible. If one or more of the bands turned maximum up or down makes little or no difference on
the meter, leave it adjusted straight up (slot vertical). Your speakers are now calibrated to the room.

SUB
Q CONTROL
The Q control allows you to tailor the bass's
character to your particular tastes and room
characteristics. (See the chart on page 2.) When
you make sensitivity or polarity changes, you may
also need to readjust the Q setting. These are
user controls and will not have any effect on the
room EQ settings. This control is adjusted while
listening to the plucked bass on test disc tracks 13
and 14. Bass should be one instrument and equal
weighting top to bottom of the scale.
INSTALLING THE SPIKES
When the best location for the SUB THREE(s) has
been found, turn the SUB THREE(s) over onto a
soft surface and install the spikes with the jam nuts
tightened against the bottom of the subwoofer. If
the SUB THREE(s) will be on a hardwood floor, a
spike shoe (available from the dealer) should be
placed under each spike to reduce the likelihood of
damage to the floor. With the spikes installed and
the placement finalized, the cables from the main
amplifier to the SUB THREE(s) can be shortened
as needed.
CROSSOVER OPTIMIZATION
Once the subwoofer(s) is broken-in, you should
again use the provided jazz recording with a stand-
up bass to evaluate the blend between the SUB
THREE(s) and the main speakers. Using the
switches inside the M5-HP crossover turn off amps
and set one setting above turn on the amps and
then listen. Then turn off the amp and reset one
setting below the original setting and turn the amps
back on and listen to the jazz recording. (Some
adjustments to the level and Q controls may be
necessary.) When you determine the best
crossover selection between the preamplifier and
power amplifier setting for your system, you are all
done.
SERVICE
In the unlikely event that your SUB THREE Subwoofer
System requires service, please follow these
procedures
1.Verify that the SUB THREE has been set up and
connected according to the Instructions In this manual.
Review the troubleshooting guide on the next page.
2.Download the R.M.A. Form and the Repair Instruction
Form and follow the troubleshooting.
3.The SUB THREE is a modular system.
4.Return the damaged or defective module and the
completed Return Authorization Form to Vandersteen
Audio. Any shipment of a complete SUB THREE to the
factory will be refused.
MAINTENANCE
All system connections should be cleaned periodically
with alcohol or a solution made specifically for cleaning
electrical contacts. The wood veneers are lacquered at
the factory and can be maintained with a light
application of Pledge or a similar product. The grille can
be vacuumed using a brush attachment that will not
snag the cloth. Care should be taken that objects that
could mar the finish are not placed on top of the SUB
THREE. The subwoofer should not be exposed to
excessive sunlight or heat, which can damage the fit
and finish of the veneer.
PACKING THE SUB THREE
To prevent physical or cosmetic damage, always pack
the SUB THREE in its original box with complete inner
packing prior to transportation or shipment. The proper
method of packing the SUB THREE is shown in the
illustration below. When you pack the SUB THREE, be
sure that the top and bottom spacers are oriented, as
shown in the illustration.

TROUBLESHOOTING GUIDE
Problem: Subwoofer hums. Audible at the
listening location.
(It Is normal for the amplifier's high-voltage
transformer to produce a slight hum, but it
should not be audible more than a few
feet away.)
Solution:
Problem:
Solution:
Problem:
Solution:
Try different grounding methods. Run a
ground wire from the SUB THREE's ground
terminal to either the preamplifier or main
amplifier.
Still hums, grounding changes didn't help.
Check your interconnect cables. Route cables
away from the amplifier. Position the M5-HP
crossover away from the amplifier. Verify that
the top cover is installed on the M5-HP. Try
the system at a very low volume level without
the M5-HP crossover installed. If the M5-HP
is the source of the hum, it will have to be
replaced before the system can be used.
Still humming, cable, and crossover
changes didn't help.
Disconnect the inputs from the SUB THREE.
If the hum is still evident at the listening
position, please contact Vandersteen Audio
as the unit needs service.
Problem:
Solution:
Problem:
Solution:
Low output level.
Verify the main amplifier's actual input
impedance and that the crossover is set to one
value lower. (See page 3.) Check the
sensitivity and Q control settings. (See pages
two and 5.) Try different placements. Positioning
the subwoofer near a corner will make the
subwoofer sound fuller and more powerful. (See
page 5.)
No output.
Verify that the SUB THREE is plugged into a
live AC outlet. (It should thump when you plug
it in.) Verify the polarity of the SUB THREE's
input wires. Unplug one channel's inputs from
the SUB THREE; if you then get output, the
input wires are out-of-phase from each other
and canceled. (See pages three and 4.)
COMMON SUB THREE QUESTIONS
To make the SUB THREE connection easier, can I
con nect the SUB THREE's wire to the main
speakers' input along with the regular speaker
wires instead of the main amplifier?
Although connecting the SUB THREE to the main
speakers may seem more manageable and, on the
surface, it looks like it should work, our tests have shown
that the performance of the SUB THREE is
compromised when it is connected to the main
speakers rather than directly to the main amplifier.
Can the M5-HP crossovers be plugged into either
the Inputs of the main power amplifier or the
preamplifier's outputs?
While it is physically possible to connect the M5-
HPs either way, connect the M5-HPs to the inputs of the
main power amplifier to minimize their interactions with
the cables ahead of the power amplifier.
Is the SUB THREE designed for use only with
Vandersteen main speakers
The SUB THREE will work well with almost any
quality loudspeaker. With multiple, moderately sized
drivers, superior pitch definition, and adjustable
sensitivity, the SUB THREE subwoofer is an excellent
match for quality electrostatic, planar, ribbon, and
dynamic speakers. Our warranty records indicate that
many different speakers have been successfully mated
with SUB THREE subwoofers.
Since bass is omnidirectional, what are the ad-
vantages of using two subwoofers instead of
one?
Modern digital sources maintain full stereo
separation down to the lowest frequencies. Bass with
phase differences between the channels is canceled
when the two channels are summed into a single
subwoofer. Stereo subwoofers reproduce all of the
bass information, complete with the phase differences
that help provide the imaging and location clues to
create a sound field. Stereo subwoofers also lend
themselves to natural placement near the comers
where the low-frequency room gain is often desirable
on music and spectacular film sound effects.
The manual says to use a jazz recording with a
stand-up bass to get the sensitivity control.
Can I use a test disc with test tones?
Single tones are not representative of the way we
hear and can result in gross mis-adjustments. As a
stand-up bass scales up and down, the notes pass
directly through the crossover range. Simply adjust the
sensitivity control so that the lower notes are the same
loudness as the upper notes using tracks 13 and 14 on
the provided test disc.
Can a SUB THREE and an older model 2W be used as a
stereo pair of subwoofers?
No, the performance differences between the
models will prevent proper integration. If you have a
2W or 2Ws, either add a second 2W or 2Wq or trade
the sub to SUB THREE.
