Welcome Thank you for choosing Oscar Duo.
We’ve spent years engineering the sound of
this loudspeaker to oer true musicality.
Oscar Duo presents a balance of intuitive design
and technological expertise. The result is music
as it should be, with vivid dynamics and a
detailed sound stage.
Our aim has always been to recreate sound as it
was recorded - bringing you closer to the live energy
and spirit of music.
For this level of detail, it’s important to ensure that
your system is of equal match to your loudspeakers.
Your amplifier, source components, cables and even
recordings can aect the sound of Oscar Duo.
It’s vital to set-up your loudspeakers correctly and
adjust them to your listening environment.
There are many factors to think about, but
careful consideration at this stage will ensure
optimum performance that you can enjoy for
many years to come.

Unpacking

How to unpack
2 x Oscar Duo loudspeaker
1 x Owner’s manual
1 x CD / USB
Unpack your loudspeakers carefully, as there are sensitive parts
that could be damaged. We suggest that you keep the box and
inserts for later transportation of your loudspeakers.
Oscar Duo is packed in 1 box. Please check the
contents when you receive your loudspeakers.
If the shipping box does not arrive in its original state,
please contact your dealer immediately.
We recommend that two people unpack and assemble
the loudspeakers.
1. Open the shipping boxes close to the intended listening place
2. Place the boxes on a firm but so surface
3. Open the box carefully to avoid scratching the speakers
4. Raise the shipping box to a standing position
5. Li the loudspeakers out of the box
6. Remove the remaining cloth material from the loudspeakers
7. Place the speaker in its intended position

Initial setup
Burning-in your loudspeakers
Your newly unpacked Oscar Duo loudspeakers need
considerable playing time in order to reach their
optimum performance.
1. Connect the loudspeakers to your system
2. Put the CD in your CD player or use the files on the USB drive
3. Choose track 1 and set it on repeat
4. Set the volume to a moderate level
We recommended the use of the burn-in track (CD/USB) to
speed up this process. Due to the high-tech materials used in the
drivers, Oscar Duo may sound a bit harsh at first.
Aer approximately 50 hours of playing your loudspeakers will
sound much better. Aer about 200 hours of playing, your
system will be optimised; the sound will be more open, detailed
and display more natural musical warmth.
Please allow the audio to run for a minimum of 24 hours
before adjusting the placement of the loudspeakers in your
listening room.

Connecting your
loudspeakers
Connections
Choosing cables
To get the most of Oscar Duo please consider the
following when connecting them to your system.
The cables you use can have a dramatic eect on the sound of
your loudspeakers. Be sure to use the same brand, type and
length of cable for each channel. Mixing dierent types and/or
lengths of cable can upset the precise timing and balance of
your loudspeakers.
Always turn o the power of your entire system before making
connections to your speakers.
We recommend using an amplifier with su∏cient power:
typically a minimum of 20 watts.
On the back of each Oscar Duo cabinet, you will find
two pairs of WBT Nextgen terminals that will accept any
standard connections.
In order to obtain the best localisation of instruments and
voices, as well as deep, natural bass, it is important to connect
your loudspeakers in-phase. The connectors on the speakers are
clearly marked with + (red) and - (white) symbols. Your amplifier
and loudspeaker cables should also be clearly marked. Keep all
markings consistent to ensure in-phase connections.
It is important to make sure that contact to the terminals is
good and the connectors are tight. Tighten the terminal posts
and then, aer a few days, retighten to make sure that the
connections haven’t become loose.

Room acoustics A good listening room has just the right amount
of reflection and absorption.
The performance of any loudspeaker depends on the speaker’s
location in the room and the acoustic conditions in that part of
the room. Furnishings, size and proportions all aect tonal
balance, imaging and bass characteristics. Large areas of glass,
mirror, or wood panelling will reflect sound waves and oen
result in brittleness and extreme brightness. You can correct this
by breaking up these sound waves with soer surfaces like
curtains or wall hangings - try to create random reflections.
Allow time to experiment with the placement of your speakers
- eort at this stage will reward you with good sound
optimisation in your room.

Positioning
Rear and side walls
Listening distance
Focusing your loudspeakers
Loudspeaker placement
Every room is shaped and decorated dierently
and therefore presents unique requirements for
the positioning of loudspeakers.
Your loudspeakers will function at their best when placed on a
flat, stable surface. Ideally, the space between the loudspeakers
should be clear and the speakers should be centred on the rear
wall. We recommend experimenting with the placement of your
loudspeakers in order to obtain the best balance, openness and
perception of depth.
For the best results, Oscar Duo should be no closer than 40 cm
(15.7”) from the rear wall. Marten loudspeakers should not be
placed close to a side wall, as reflections from these can disturb
the depth of the sound image.
The listening distance should be no closer than 2m,
but preferably 2.5m or greater
Oscar Duo loudspeakers deliver excellent imaging. To make the
most of this, the loudspeakers should be toed in towards the
listening area to focus the sound.
Ideally, your listening position and each loudspeaker
should form an equilateral triangle. The goal is to have a
balanced sound. Track 2 of the enclosed CD / USB can be
used to help focus the soundstage. With this track,
you should be able to place the recorded voice in the
centre of your speaker arrangement.
The amount of toe-in will depend on the room environment and
dimensions, as well as your listening preferences. Take time to
experiment with your listening position and the position of your
loudspeakers. This will give you a more precise sound image.

Enclosed CD / USB
Care of your loudspeakers
The enclosed CD and USB contains tracks to help you
set up your loudspeakers. There are also three tracks
purely for your listening pleasure; these were
recorded in our studio in Gothenburg, Sweden.

Marten loudspeakers require no special treatment
apart from careful handling, as you would with any
high-tech product in your home.

2. The Look Of Love** - Jeanette Lindström & Steve Dobrogosz
3. Blue In Green - Tommy Kotter
4. I Can’t Believe He Never Said Goodbye - Åsa Tåhlin, Mitch
Hiller & Peter Axelsson
5. Lady’s A Tramp - Mitch Hiller & Peter Axelsson
Because many dierent materials are used in the making of the
loudspeakers, all-in-one cleaning materials should not be used.
Never use abrasive materials or cleaning fluids.
The cabinet and other parts should only be cleaned with a so,
dry cloth or one slightly dampened with water.
* Use to burn-in your loudspeakers
