1.0 INTRODUCTION
Congratulations on your new DALI IKON MK2 subwoofer. Please read this manual thoroughly
before unpacking and installing the subwoofer in order to get the most from your purchase.
You can find more information on our website: www.dali-speakers.com or by contacting your
authorised DALI dealer.
2.0 UNPACKING
Be careful not to damage the contents when unpacking the parts (see Figure 1). Check that all
parts are included in the cardboard box (see Table 1). Keep the packaging materials in case your
subwoofer needs to be relocated or serviced.
3.0 POSITIONING
Both the amount and quality of the deep bass depend on the size and shape of the room, the
position of the subwoofer(s) and the main speakers. If positioned near a side or back wall, the
bass will be accentuated. A corner position will accentuate it even more, and we recommend
this position, as it increases the maximum bass output while simultaneously reducing the risk of
overloading your subwoofer.
DALI IKON SUB MK2 features a front-firing woofer and located at the rear side of the subwoofer
is a heat sink, which can become hot when the subwoofer is powered. Prevent the heat sink from
being blocked or covered. Ensure a minimum distance of 5 cm/2” between the heat sink and the
nearest obstacle to secure free airflow around the heat sink.
4.0 CONNECTION
DALI IKON SUB MK2 has a built-in power amplifier with an active crossover. The inputs of the
subwoofer amplifier should be connected to your stereo or surround sound (pre-) amplifier/
receiver using a RCA cable (sold separately). When changing connections, always disconnect the
mains voltage from the subwoofer to prevent damage.
The subwoofer can be connected to your stereo or surround sound amplifier/receiver in two ways:
1) LINE input: the signal from the amplifier is low pass filtered inside the subwoofer using
one or both of the LINE INPUTS. This way of connecting the subwoofer is typically used for
connecting to a stereo amplifier/receiver.
2) LFE input: the signal from the amplifier is filtered inside the amplifier when using the LFE
input connector. This way of connecting the subwoofer is typically used for surround sound
(A/V receiver) Setups.
NOTE: When the subwoofer is connected to the music/home cinema system, don’t power up the
subwoofer until all other components are “on”.

4.1 STEREO CONNECTIONS
If you want to use DALI IKON SUB MK2 in a stereo setup, your stereo (pre-) amplifier/receiver
should have either a set of stereo RCA line outputs or a mono RCA line output available (please
refer to the instruction manual of your stereo (pre-)amplifier/receiver). The line output connector(s)
of your stereo (pre-)amplifier/receiver must be connected to the LINE INPUT connectors (L+R) of
the subwoofer via one or two RCA cables (sold separately).
4.2 SURROUND SOUND CONNECTIONS
4.2.1 LINE INPUT
Use the LINE INPUT connectors L or R if you want to adjust the subwoofer Frequency output using
the DALI IKON SUB MK2 crossover button.
To use this option, connect the subwoofer output connector(s) of your surround sound (pre-)
amplifier/receiver with the LINE INPUT connectors on the subwoofer using a RCA cable (sold
separately). If the surround sound (pre-) amplifier/receiver has only one subwoofer output
connector, connect it to the LINE INPUT L connector (white) of the subwoofer using a RCA cable.
Please refer to chapter “5.0 Installing and Adjusting” for instructions on how to make
the adjustments.
4.2.2 LFE INPUT
Use the LFE input connector (red), if you want to adjust the subwoofer output from your surround
sound (pre-) amplifier/receiver. When the LFE input connector is used the built-in crossovers are
bypassed and the crossover frequency adjustment button will not be functioning.
To use this option, connect the surround sound (pre-) amplifier/receiver subwoofer output to the
LFE input connector on the DALI IKON SUB MK2 with a RCA cable (sold separately).
Please refer to the instruction manual of your surround sound (pre-) amplifier/receiver on how to
adjust the crossover settings.
4.3 USING TWO SUBWOOFERS
In most cases you will achieve excellent results with one DALI IKON SUB MK2. Use of two
subwoofers is possible as a no-compromise stereo solution, or for reproduction of very powerful
sound pressures in a stereo or surround setup in larger rooms.
The connections are basically the same as stated in previous chapters, but for stereo you should
only connect the left channel output connector of your stereo or surround (pre-) amplifier/receiver
to the LINE INPUT L connector on the DALI IKON SUB MK2 placed to the left in your room. In a
similar way you should connect the right channel output connector of your stereo or surround
(pre-)amplifier/receiver to the LINE INPUT R connector on the DALI IKON SUB MK2 placed to the
right in your room.
For a surround setup, split the output signal from your surround sound (pre)amplifier/receiver
using a RCA splitter (sold separately) and connect the two outputs. In all other respects, follow the
instructions above - but use separate channels. Please consult your authorised DALI dealer if you
have further questions.

5.0 INSTALLING AND ADJUSTING
Start by checking that the voltage of your mains output corresponds to the indication on the back
of your DALI IKON SUB MK2.
WARNING: If the wrong voltage is supplied there is a serious risk that the electronics of the
subwoofer will suffer permanent damage.
After checking theVOLTAGE,connect the mains cable and move the POWER switch to ON.Adjusting
the subwoofer is done using the controls on the rear side of the subwoofer in accordance with the
following tuning method, which will help you achieve the best results: Play a piece of music you
know well, preferably one including rhythmic bass such as kettle drums, bass guitar etc.
Since the performance is highly dependent on the main speakers, the listening room, the
subwoofer position in the room and your personal preferences, we recommend experimenting
with different settings to achieve the best listening results rather than giving any specific advice
on settings.
NOTE: The position of the subwoofer will significantly affect its contribution to the overall sound
(see chapter “3.0 Positioning”). When you have decided which method of connection you want
to use and you have positioned the subwoofer, you can begin the process of tuning the system.
You are now ready to adjust your DALI IKON SUB MK2.
5.1 PHASE SETTING
The PHASE switch of the subwoofer has two settings: 0 degrees or 180 degrees. The phase
setting will adjust the timing between the subwoofer and the main speakers. To set the phase,
do the following:
1) Turn up the volume of your subwoofer (see figure 3) a little higher than you normally would.
2) Set the crossover point to maximum (130 Hz).
• NOTE: If you have connected the subwoofer via LFE instead of LINE IN you need to set
the crossover point for your subwoofer to maximum in the menu of your surround sound
(pre-) amplifier/receiver.
3) In your listening position, play music of the type previously described.
4) Toggle between 0° and 180° while focusing on the bass output.
The optimal setting of the PHASE switch is where you experience maximum bass output.

10
5.2 VOLUME ADJUSTMENT
On the rear of the subwoofer you can increase or reduce the volume by turning the VOLUME
control clockwise or counter clockwise. The volume should be adjusted so that the bass matches
the level of your main speakers. You should be able to appreciate your subwoofer’s contribution
to the overall sound without it ever being overpowering. Bass must be tight and accurate so that
the subwoofer reproduces the exact amount of bass present in the music/soundtrack; no more
no less. When installing the DALI IKON SUB MK2 in a surround sound system, we recommend
selecting a fixed level on the sub and adjusting the subwoofer output using the surround (pre-)
amplifiers/receivers setup function.
If bass levels are set too high, distortion will reduce the quality of your listening experience.
Remember that you can boost the bass level by selecting a physical position close to the wall or
even better – in a corner (see chapter “3.0 Positioning”).
5.3 CROSSOVER FREQUENCY ADJUSTMENT
Once you have set the phase and the volume level, you need to adjust the overlap between the
main speakers and the DALI IKON SUB MK2.
5.3.1 USING LINE INPUT
The crossover frequency adjustment on the subwoofer is only possible when using the
LINE INPUT(S).
On the rear of the subwoofer, adjust the CROSSOVER button upwards until you can hear the bass is
even with no drop-outs (Frequency range 50-130 Hz). Smaller speakers typically require a higher
crossover point, whereas larger speakers will accept a lower crossover point. When using your
DALI IKON SUB MK2 together smaller speakers, e.g. the DALI IKON 2, we recommend a crossover
point of approximately 90 Hz (12 o’clock position).
After having adjusted the crossover frequency you may have to re-adjust the volume to
optimise performance.
5.3.2 USING LFE INPUT
When using your DALI IKON SUB MK2 together smaller speakers, e.g. the DALI IKON 1, we
recommend a crossover point of 100 Hz. This must be entered in the menu system of your
(pre-) amplifier/receiver. You might need to enter the ‘small’ setting when selecting type of front
speakers in the AV receiver menu.
Using larger speakers (typically floor-standing front speakers) will allow you to choose a lower
crossover point, and to define your speakers as ‘large’ in the menu system.
If in doubt about the capacity of your speakers, we recommend setting the crossover point quite
high, defining your speakers as small, and finally reducing the crossover point to the lowest
possible position while maintaining an even bass with no drop-outs.

11
5.4 POWER
The POWER button is the main ON/OFF switch.We recommend switching OFF the subwoofer when
it is not to be used for extended periods. When the POWER button is set to OFF there will still be
voltage inside the subwoofer. If you completely disconnect the subwoofer from the mains voltage,
please be sure to remove the mains plug from the subwoofer.When changing connections, always
disconnect the mains voltage from the subwoofer. We recommend that you ALWAYS turn OFF the
IKON MK2 SUB on the rear side of the subwoofer BEFORE turning off the mains switch.
5.5 ON/STAND BY
The subwoofer has a built-in circuit that will power up the amplifier of the subwoofer when an
input signal is detected (given that the POWER is set to ON and the power mode switch is set to
AUTO). When the subwoofer is ON, the ON/STANDBY LED will light green. If an input signal is not
detected for approximately 20 minutes, the subwoofer will go into standby mode and the ON/
STANDBY LED on the rear of the subwoofer will light red.
6.0 RUNNING-IN
You should expect the sound quality from your new subwoofer to gradually improve during the
initial period of use. Nothing particular has to be done in order to run in the subwoofer – but expect
up to several hours of playback (depending on playback level) before full performance level is
reached. Use normal music for running-in the subwoofer.
7.0 OVERLOADING
If DALI IKON SUB MK2 is overloaded, the built-in safety circuit may power down the subwoofer.
The subwoofer will power on again when the temperature of the built-in amplifier is within safe
working range.
If overloaded, we recommend that you turn off the subwoofer for a few minutes before turning it
on again.
NOTE: The built-in safety circuit is no guarantee against damage as a result of overloading.
8.0 MAINTENANCE
Cleaning the subwoofer surfaces can be done with ordinary household cleaning agents and using
a micro fibre cloth. Avoid using products that are abrasive or contains acid, alkali or anti-bacterial
agents. Avoid using aerosols. Avoid using cleaning agents directly on the drive unit and clean this
with extreme care.
8.1 AVOID DIRECT SUNLIGHT
The surfaces of the subwoofer may fade or become discoloured over time when exposed to direct
sunlight. Therefore avoid positioning the subwoofer in direct sunlight.
9.0 DISPOSAL
DALI products are designed to meet the international directives concerning Restriction of Hazardous
Substances (RoHS) and disposal of Waste Electrical and Electronic Equipment (WEEE). The waste
symbol indicates that the speakers meet the directives (see Figure 2). The subwoofer must be
processed or recycled appropriately. Please consult your local waste authority for guidance.
