Introduction  
Dear Music Lover,  
Thank you for your decision to acquire Dynaudio loudspeakers.  
Every Dynaudio model features the advanced Dynaudio loudspeaker technology,  
resulting in music reproduction at a very high level, making many familiar recordings a  
new listening experience altogether. This advanced technology results from many years  
of intense research and development, the highest quality standards in production, and  
Dynaudio's enduring passion for musical truth.  
Dynaudio is one of very few companies who can realize such loudspeaker concepts  
through it's own in-house development and production facilities. These facilities are so  
advanced and the quality control is so strict that Dynaudio is TS16949 certified.  
Each loudspeaker is constructed by Dynaudio's master craftsmen in Denmark to these  
high standards of quality. To realize the highest sound quality from the loudspeakers,  
some areas should be addressed, as will be explored on the following pages. By  
considering the tips and suggestions, you will achieve the maximum performance and  
enjoyment of the loudspeaker and it's advanced musical capabilities for a long time to  
come.  
We wish you many years of enjoyment experiencing music,  
Dynaudio

2. The packaging should be opened from the top. Remove all accessories that come  
packed with the subwoofer. Do not remove the top part of the protective material.  
3. With the protective material still in place but with accessories removed, carefully tilt  
the packaging on its side and tilt again to turn it upside-down. Ensure that no part of  
the top-cover is obstructing the opening at the top.  
4. The outer packaging can now be lifted away from the subwoofer itself. Remove the  
protective material that now is on top. Through the bag you can now see the  
underside of the subwoofer.  
5. Open the bag and remove such from around the base of the subwoofer.  
6. Again, carefully tilt the subwoofer on its side and again to turn it onto its feet. Note that  
the top part of the protective material will now come off easily so ensure that the  
subwoofer does not drop or slide away in the process.

Unpacking  
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.

OPERATION  
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.

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).

OPERATION  
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.  
Combined frequency response  
Subwoofer  
Main speakers  
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.

Setting the satellite cut-off frequency (SAT Highpass)  
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.  
SAT Highpass SUB Lowpass  
Flat 60Hz 80Hz  
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.

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.

Positioning the subwoofer  
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.

1/4  
1/2  
Listening Room  
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)  
3/4  
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.

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.

General tips  
Check it out  
Try different subwoofer positions and settings, before you finally choose a setup.  
Note down settings  
When looking for the best subwoofer position in the room, note down the ideal setting you  
found for a position. When moving the subwoofer between two positions you will be able  
to set the subwoofer to the same configuration as found before.  
Vary the listening music  
When experimenting to find the optimal settings, 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. covering a wide spectrum in the bass region  
and above, are very suitable as these depend on accurately balanced subwoofers and  
main speakers.  
Verify changes  
Although in general it is best to make adjustments in the sequence outlined below, note  
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.

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.  
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  
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.

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.

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.

In the other case you will experience unnatural and bloated bass sound, if the overlapping

Cut-off frequencies  
Control possibilities  
The Dynaudio Sub 600 provides two controls to match the frequency response of the  
subwoofer and the main speakers perfectly:  
SAT Highpass SUB Lowpass  
Flat 60Hz 80Hz  
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.  
50 Hz  
150 Hz  
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.

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  
Damage of Small Satellite Speakers  
CAUTION  
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.
