1. INTRODUCTION
Our Story
There can be few world-class rms that have been founded at the
breakfast table, but Estelon – from Tallinn, Estonia – is certainly one of
them. The high-end audio brand traces its origins back many decades
when a young boy obsessed with music, began to take apart radios
and adjust them to improve the sound quality.
Before Estelon, Alfred had been designing speakers for other compa-
nies for over 25 years and spent many years researching opportunities
to achieve his ambition.
He always sought perfection and overcame challenges: growing up
in Soviet era, when resources were limited, he dismantled radios to
rebuild and improve them.
He took his interest to university, studying electro-acoustics in St Pe-
tersburg. These experiences enabled Alfred to develop technologies
and nd materials with which to construct unique and innovative
products. These were combined with inspiration from nature – par-
ticularly from the lush and expansive forest landscapes of Estonia – to
create the perfect balance between engineering and design.
The result was Estelon, one of the world’s most luxurious speaker
brands. It derives aesthetic and acoustic excellence through the merg-
er of ingenious creativity and cutting-edge science. Each decision –
from engineering techniques to materials and components used in
the manufacturing process – is made with the perfect harmony of the
speakers as a whole in mind.

Estelon Extreme
By elevating the act of listening to new heights, Estelon delivers an
audio experience like no other. At the forefront of this sound revolu-
tion is our agship model, Estelon Extreme. The system comprises an
upper and a lower module, with the former fully adjustable to best
suit a room’s acoustic attributes and the listener’s personal preferences.
With its soaring, handcrafted cabinet and sleek two-tone nish, the
speaker system is a statement piece, but one that doesn’t need to
shout about its achievements. Indeed, the Extreme has been designed
to perform a smart disappearing act when in use: instead of having
your ear drawn to the speaker, the listener is immersed in sound, expe-
riencing music afresh in all of its nuanced splendor.

Engineering Concept
Each element and its characteristics play a crucial role in delivering
the purest sounds imaginable. All Estelon products are built from the
inside out. That means that the shape is the result of decades of engi-
neering and experiences on how to create the best conditions for mu-
sic reproduction. Taking this into account there are not many materials
in the world which can adhere to all of the necessary conditions.
Cabinet Materials and Finish
Our Extreme model cabinets are built using a proprietary marble
based composite material. This allows to create the perfect form and
shape of the speaker. The specic shape and materials eliminate any
extra internal resonances and difractions and therefore the sound is
pure and natural without coloration.
The nishing techniques of all our speakers come from the automo-
tive industry, which makes the coating very durable. The nishing is
handcrafted and consists of up to 12 layers and is then carefully hand
polished. The Estelon Extreme is oered in a choice of Gold, Copper,
Dark Silver and Black Lava liquid gloss in combination with Black Matte.

3. UNPACKING AND SET-UP
Your Estelon Extreme loudspeakers come in four ight cases and a box
with set-up frame. We strongly recommend keeping the ight cases
for possible future use or transport.
Bring the four ight cases for unpacking as close as possible to the
speakers positioning point. Due to the substantial weight and slippery
surface of the loudspeakers we suggest that three (3) persons assist in
the unpacking and positioning of them for listening.
Contents of the four (4) ight cases:
• Pair of loudspeakers:
• 2 Lower Modules
• 2 Upper Modules
• 1 Controller box with connecting cable and power cord;
remote control
• 1 Accessories box:

Unpacking and set-up
For unpacking and setting up the loudspeaker please watch a demo
video of the correct procedures from the Downloads – User Manuals
section on the Estelon homepage.
www.estelon.com/downloads/#manuals/extreme
Please keep all the removed parts for future re-assembling and/or
transportation. Keep the remote control out of reach of children!
Recommended positioning point
The positioning of the speakers in the room must be symmetrical for achiev-
ing a balanced sound stage – this is very important in a narrow room. Expect
the distance between the speakers to be approximately 3 – 5 m, depending
on the size of the room and its reverberation characteristics.
When positioning the speakers in your room, if possible, it is better to allow
for“free”space around the speakers so as to assist in minimizing sound re-
ections from walls, furniture etc. This will help in achieving correct tonal-
ity, realistic imaging, focus and dynamics. The recommended minimum
distance between the speaker and the nearest reection point is 1.2 m.
The distance between the back wall and the speaker should not be
less than 1 m, the distance from the speakers’front to the back and side
walls must not be too similar.
Listening point: the best listening height is approx. 1 m, while the dis-
tance between the listener and the speakers should be similar or lon-
ger to the distance between the two speakers.
The recommended speaker’s direction is usually 3-7° towards the lis-
tening position, depending on the listening room specics.
WARNING! When played at excessive volume, you stand the risk
of doing damage to the drivers.

Wiring
When connecting the speaker to the amplier please make sure that
the amplier is in an o position.
Connect the speaker cable to the pole terminal on the back of the
speaker: speaker terminal „+“ with the amplier terminal „+“ and „-“
with „-“. For single wiring we recommend connecting cables to upper
binding posts (please keep the wire jumpers connected between up-
per and lower binding posts).
For signal ow, please follow the direction marked on the cable or in
the cable manufacturer’s instruction. Typically, the signal ow will be in
the same direction as the labeling / writing on the cable.
Estelon Extreme can be also bi-amped or bi-wired at your choice. In
this case remove wire jumpers to be able to use all connectors. Con-
nect one cable to upper binding posts and another cable to lower
binding posts: speaker terminal„+“ with the amplier terminal„+“ and
„-“ with„-“.
