Grille
The subwoofer can be operated without the grille. However, it is recommended that the
grille is mounted during normal use to help prevent accidental damage or dirt settling on
the cone of the loudspeaker. With subwoofers, the influence of the grille on the sound is
virtually negligible.
To remove the grille:
Gently pull the grille at all corners.
To fit the grille:
Line up the studs with the corresponding front baffle holes.
Gently push the grille in at all corners.
Note: Be careful when mounting the grille not to touch the cone of the loudspeaker itself.

Subwoofer inputs
The Dynaudio Sub 600 provides two different signal inputs:
SUB I/O - LFE/Slave In
This input allows the LFE (Low Frequency Effect) channel to be connected, which is used
in Home Cinema systems to reproduce low frequency effects.
The signal is:
• reproduced by the subwoofer
• routed to the SUB I/O - LFE/To Slave output for a second subwoofer to be
connected.
The SUB Lowpass control has no impact on this input.
SAT/SUB Input
This input allows the connection of the full bandwidth signal from the processor/receiver
(preamplifier out).
The signal is:
• reproduced by the subwoofer,
• routed to the SAT Output terminals. Low frequencies are cut-off according to the SAT
Highpass setting,
• routed to the SUB I/O - LFE/To Slave output for a second subwoofer to be
connected. High frequencies are cut-off according to the SUB Lowpass setting.
See figure left for correlations between input, output and settings.
Note: All Sub 600 inputs and outputs are low level terminals. Thus, neither a power
amplifier output must be connected to the subwoofer nor passive loudspeakers
can be driven by the subwoofer directly!

This signal should not be already processed by the processor/receiver. Please pay
attention to the settings of your processor/receiver.
➋ To connect the LFE channel:
From the processor or receiver’s low-level (not a speaker output) subwoofer output
(often marked as “subwoofer out”, “Sub out” or “LFE”), connect a mono RCA-to-RCA
cable to the subwoofer input SUB I/O - LFE/Slave IN.
This signal should not be already processed by the processor/receiver. Please pay
attention to the settings of your processor/receiver.
Set the MODE switch to LFE.
Note: You also can use both connection types. Both signals will be combined in the
Sub 600 and routed accordingly. This allows the Sub 600 to reproduce both the
LFE channel information as well as the bass range of the connected satellite
speakers

Connecting the subwoofer
Multiple subwoofer connections
The Dynaudio Sub 600 can be used stand-alone or together with multiple subwoofer
units. Using multiple units may be helpful if the listening room is quite large or has difficult
acoustic conditions (e.g. room-modes, see also “Positioning the subwoofer” on page 20
for further information).
When using two or more subwoofers, the first one (designated “Master”) controls the
following subs (designated “Slave”) via a subwoofer cable.
To connect multiple subwoofers:
1. Connect the first subwoofer with the processor/receiver as described before.
2. Set MODE switch of first subwoofer to LFE.
3. From the OUT - To Slave output of the first subwoofer connect a mono RCA-to-RCA
cable to the SUB I/O - LFE/Slave IN input of the following subwoofer. This now
becomes the slave.
4. Set the MODE switch of the second subwoofer to Slave.
Further subwoofers can be connected in the same way. Set the MODE switch of all
following subwoofers to Slave respectively.
Note: In order to avoid interference and noise, we recommend you use quality, well
shielded cables.
When using multiple subwoofers in a Master-Slave setup, it is recommended that
the subwoofers are all the same model.
If you wish to use multiple subwoofers with full individual control, set the Input
switch for all to the “Master” position. From the Amplifier, processor or receiver’s
subwoofer output, use a Y-connector.

Connecting loudspeakers
In Home Cinema systems the bass management - meaning the distribution of the low
frequencies to the subwoofer and the speakers - is handled by the settings of the
processor/receiver. If your equipment does not provide bass management, or if you want
to use the Sub 600 together with a common stereo, the low frequency adjustment of the
connected speakers can be managed by the Sub 600. This not only improves the sound
by matching subwoofer and speakers, but also by freeing the power amplifier and
connected speakers from the effects of sound-compromising bass reproduction. Also
refer to the further explanations in the chapter “Connecting the subwoofer” on page 10.
To connect speakers:
1. Connect the subwoofer with the processor/receiver as explained in “Connecting a
single subwoofer” on page 12.
2. From the Subwoofer SAT Output connect a RCA cable to the Main In of the power
amplifier you use for your speakers.
Note: Stereos do not have a LFE channel. In this case just connect the front outputs of
the processor/receiver (Front Out/Pre Out) with the subwoofer.
The signals connected to the SAT/SUB Input are provided at the OUT - To Slave
output for connecting another subwoofer. See page 13 to learn more about
connecting multiple subwoofers.

Selecting the subwoofer cut-off frequency
(SUB Lowpass)
The SUB Lowpass control allows the frequency range of the subwoofer to be defined.
Above the selected frequency the sound level decreases rapidly. The correct setting of
this cut-off frequency is important for a well balanced combination of subwoofer and
speakers.
To select the cut-off frequency:
Set the SUB Lowpass control to the desired frequency between 50 and 150 Hz.
Note: In most audio-video-systems the subwoofer cut-off frequency is already set in the
bass management of your processor/receiver. Please refer to the operating
manual of your processor/receiver for further information. If possible, switch off
any settings. If your processor/receiver does not allow to switch off the bass
management, set it to the desired frequency and set SUB Lowpass to its
maximum value (turn to the very right, 150 Hz).
Please also heed the instructions given in the operating manual of your loudspeakers,
and refer to “Cut-off frequencies” on page 25 for further information.

Setting the phase (PHASE)
With the phase settings you can adjust the timing relationship between the subwoofer and
main speakers. If either subwoofer or main speaker are slightly delayed in response in
relation to the other, it can result in decreased bass output in the frequency response area
where they overlap each other.
The phase relationship between subwoofer and satellite speakers is very dependent on
relative distance, construction and working principles of the main speakers. The figure on
the left shows a case whereby phase of the subwoofer and main speakers are incorrect
in the critical overlap area, thus significantly reducing acoustic output in the listening room
in that area.
To find the correct phase setting:
1. Play a bass-rich track which also covers the overlap area.
2. Toggle the PHASE switch between 0° and 180°.
Choose the setting for which you experience the most bass.
Note: You can not set the phase if the subwoofer is in slave mode. In this case the
phase is controlled by the setting of the master subwoofer.

Setting the satellite cut-off frequency
(SAT Highpass)
Depending on the bass capabilities of the speakers, the frequency range of subwoofer
and speakers can overlap between 50 Hz and 150 Hz. A bump or a gap in the frequency
response and thus a lower sound quality will be experienced if the system is not matched
properly. In addition, small speakers and low powered amplifiers will particularly be
affected by the low frequency signals, which again has an negative effect on the sound
quality. Therefore it makes sense to limit the bass range of the connected speakers
(called “satellites” in this case) by a highpass filter. The Dynaudio Sub 600 provides three
settings to achieve this:
• Flat = no limitation
• 60 Hz = frequencies below 60 Hz are cut-off
• 80 Hz = frequencies below 80 Hz are cut-off
To set the cut-off frequency:
Switch SAT Highpass control to needed position.
Note: In most audio-video-systems the satellite cut-off frequency is already set in the
bass management of your processor/receiver. Please see the operating manual of
your processor/receiver for further information. You can decide whether you use
the processor/receiver or the subwoofer for setting the cut-off frequency. Just take
care, not to set it twice by setting either of them to Flat.
Owners Manual 19
OPERATION
Positioning the subwoofer
Although it is often said that the location of a subwoofer in a listening room is not critical
(as the human ear can not locate direction at very low frequencies), we recommend that
you choose its position carefully. Thus the subwoofer can integrate seamlessly with the
other speakers in the system and interact correctly with the room acoustics.
All of the following should be taken as rough guidelines; bass response in general is very
dependent on the acoustics of the listening environment. Finding the best position often
involves a lot of trial-and-error experimentation. Always trust your ears, even if the
position of the subwoofer seemingly goes against the guidelines. Contradictory as it may
seem, good integration of subwoofers has been achieved when one isn’t aware that a
subwoofer is present at all in the system, yet performance involves fast, deep and solid
bass without sounding stressed, even at loud levels.
Choose adequate music material
When experimenting to find the optimal location, use a couple of music tracks with
repetitive bass across a large spectrum. The tracks should be sufficiently different from
each other and each should cover a wide bass-range. Musical instruments, such as a
double-bass, bass guitar, church organ, etc. cover a wide spectrum in the bass region and
are therefore very suitable. Using non-music (such as action movies) material to position
and adjust the subwoofer with, may lead to spectacular results with such material but
almost always it will result in overblown and excessive bass when playing music with the
same setting.

Listening Room
Impact of room-modes
Every listening environment will have specific “room-modes”, whereby in some specific
locations in the room and at particular frequencies, the bass may be too much or too lean.
This effect will be stronger in square and “shoe-box” shaped rooms. With a single
subwoofer, the better position for the subwoofer relative to the listening position will be the
one where bass is perceived to be neither too much nor too lean at any given frequency.
Avoid placing the subwoofer at 1/4, 1/2 or 3/4 of either the length or width of the room
as at these locations the room-modes are likely to be strongest (the dashed lines in the
figure)
Note: Always position subwoofers at least 1 mtr/3 ft away from a CRT television as the
magnetic field emanating from the subwoofer may otherwise distort the picture. If
you see discoloration on the television screen, try moving the subwoofer and other
speakers close by away from the television.
Owners Manual 21
OPERATION
Positioning possibilities
Moving the subwoofer closer to walls and corners in particular will generally increase the
amount of bass. Although the extra amount of bass can be compensated for by reducing
the volume level of the subwoofer relative to the rest of the system, this can result in
uneven bass response at the listening position. You can try starting with placement in a
corner and experiment by gradually moving it out of the corner or further away from the
wall. Try to locate the position which yields the best compromise between position, volume
and even bass response. Note that every time that you reposition the subwoofer (even if
it’s over a short distance) you may need to adjust the level and phase settings again.
Corner placement
This placement yields maximum boost of bass level but potentially uneven distribution of
bass in the room (room-modes), particularly if the room is square or shoe-box shaped.
From the listening position, check if the bass is even across the entire bass spectrum.
If not, move the subwoofer out of the corner. Try moving it along either wall.
Next to wall, away from corner
This position still provides considerable boost but less than the corner placement as
above. Room-modes can also still be considerable but less so than with corner
placement.
From the listening position, check if the bass is even across the entire bass spectrum.
If not, move the subwoofer away or towards your listening position until the most even
response has been obtained.
Avoid placing the subwoofer exactly half-way or at a quarter of the wall’s length.
Free standing, away from wall and corner
This position will give least boost compared to wall or corner placement, but in general
offers the best flexibility at achieving most even bass distribution at the listening position.
Avoid placing the subwoofer exactly half-way or at a quarter’s length of either sidewall.
Particularly in smaller square or “shoe-box” shaped rooms the free standing position
is recommended.

Positioning the subwoofer
Using multiple subwoofers
By using carefully positioned multiple subwoofers it is possible to even out the different
room-modes and thus create a more coherent overall bass response in the room. It is
worth experimenting with different locations around the room for the additional
subwoofers, even using the rear of the room. As adding subwoofers will not increase the
effect of room-modes, even adding a subwoofer without much care or thought to
positioning is likely to help even out room-modes.

repetitive bass across a large spectrum. The tracks should be sufficiently different from

that changing one setting may influence another. For example, finding the right setting for
phase may result in having to decrease gain, even if this was set correctly before. It is
recommended that you double-check the previous settings before moving on to the next
one. Obtaining the best integration of the subwoofers generally involves a considerable
amount of repeated fine-tuning.

With the GAIN control you can adjust the relative volume level of the subwoofer to the
main speakers of the system:
Play the same track a couple of times, adjusting the level so that the instrument sounds
homogenous across its range.
If you find that at certain specific bass tones the response is either too loud (bloated
sound) or soft (thin sound), it may be that you have to experiment further with the location
of the subwoofer and/or the cross-over settings.
Refer to the sections “Positioning the subwoofer” on page 20 and “Cut-off frequencies”
on page 25 for further information.
Note: When using multiple subwoofers, ensure that the settings for cut-off frequency,
phase and LF extension are identical. Use the LFE and Slave mode options to
ensure that all subwoofers operate on the same settings (refer to chapter “Multiple
subwoofer connections” on page 13).
Different acoustic loadings can be found within a listening room. Thus, balancing
out modes may require different power levels.
Cut-off frequencies
Matching the frequency responses of subwoofer and speakers has an important impact
on the overall sound quality, when integrating a subwoofer into a audio-video-system. In
general a large, floor-standing speaker still has significant output in the deeper bass
range, whereas a very small speaker will not be able to reproduce deep bass at all. In the
first case a bump in the overlapping area will cause a louder or even bloated sound while
in the second case an acoustic hole will be experienced.
The following figures visualize the possible results (please note that all curves are for

Cross-over frequencies set correctly
Subwoofer and main speakers are perfectly matched, when the combined frequency
response is smooth without bumps and gaps. A neutral sound will be the result.
Subwoofer too low, main speakers too high
A gap in the frequency response occurs, if the cut-off frequency of the subwoofer is set
too low and of the main speakers too high (or if the main speakers are not able to
reproduce low frequencies accordingly). In this acoustic hole you will miss some signal
information and experience a thin bass sound.
Subwoofer too high, main speakers too low
In the other case you will experience unnatural and bloated bass sound, if the overlapping
area is too large. The combined frequency response shows a bump, as the sound
pressure levels in this area are increased.

Control possibilities
The Dynaudio Sub 600 provides two controls to match the frequency response of the
subwoofer and the main speakers perfectly:
• SUB Lowpass: The upper cut-off frequency of the subwoofer, which can be
continuously adjusted between 50 and 150 Hz. Above the selected cut-off frequency
the sound pressure level decreases rapidly.
• SAT Highpass: The lower cut-off frequency of the main speakers; 60 Hz, 80 Hz or
Flat (neutral) can be selected. Below the selected cut-off frequency the sound
pressure level decreases rapidly.
Note: The settings for the cross-over frequencies just have an impact on the signal at
the SAT/SUB Input! The LFE channel is just used to reproduce very low frequent
effect signals. Consequently signals at the SUB I/O - LFE/Slave In are not limited
in their frequency response.
General tips
SUB Lowpass = 80 Hz
The cut-off frequency should be selected as low as possible. Then the subwoofer
works without being recognized as a single signal source. Very often a cut-off
frequency of 80 Hz has been experienced as an ideal value.
Reduce weak amplifiers and small speakers from bass load
By limiting the reproduction of low frequency at the SAT Output, amplifiers and
speakers connected to this output are freed from reproducing the heavy bass load,
which negatively impacts the sound quality. This will improve the overall sound of your
audio system.
Play a music track that has a significant amount of bass over a large bass region. An
instrument such as a double-bass or bass-guitar is very suitable. Listen carefully to the
bass-line played by the instrument. As it goes up and down in the bass range, the
overall bass volume should remain the same – be it with very deep or higher bass
notes.
Owners Manual 27
OPTIMIZING SETTINGS/TROUBLESHOOTING
Specific tips
Many processors/receivers provide extensive bass management capabilities to set the
cut-off frequencies for both subwoofer and speakers. If using the bass management of the
processor/receiver, set the controls of the Sub 600 as followed:
• SUB Lowpass = 150 Hz (at the very right)
• SAT Highpass = Flat
CAUTION
Damage of Small Satellite Speakers
Selecting the correct frequency depends to a large extend on the main speakers.
Sometimes main speakers are specifically intended to work with a subwoofer. In such
cases, the main speakers can get damaged by a full-range amplifier signal.
If in doubt, check the instruction manual for the main speakers for any restrictions.
The table below offers some setting tips for different speaker and amplifier combinations.
This should only be taken as rough guidelines, as the best setup can just be found by
experimenting.
