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 Forza
The Estelon Forza is an much awaited addition to the Estelon agship
series. Standing at nearly 1,7 metres in height, the elegant design of
the Forza features the very best of what Estelon has to oer. The per-
fect synergy between aesthetics and engineering. Using only the ma-
terials and components best suited for this model and manufacturing
it with the greatest detail, the Forza brings music to life. With a sleek
design and composed of a single cabinet, the Forza is just a bit smaller
in size than the Estelon Extreme.
Forza, as the name already suggests, is full of unimaginable rened
power. As the electric power passes through the driver elements, the
Forza becomes alive. Every nuance dances through the air, creating a
realistic soundstage, bringing rich emotions so you can close your eyes
and enjoy the best what music can oer.
Alfred Vassilkov, the Designer and Founder of Estelon

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 nish
Our X-Series and our Flagship model cabinets are built using a propri-
etary marble based composite material. This allows to create the per-
fect form and shape of the speaker. The specic shape and materials
eliminate any extra internal resonances and difractions and therefore
the sound is pure and natural without coloration.
The same ideology is also used for the YB speaker, using only the ma-
terials that t best the speaker’s characteristics.
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 Forza is oered in a choice of liquid gloss, matte
or the optional nishes.

3. UNPACKING INSTRUCTIONS
Your Estelon loudspeakers come packaged individually in 2 separate
ight cases – we strongly recommend keeping these cases for possi-
ble future use / transport. Due to the substantial weight and slippery
surface of the loudspeakers we suggest that two persons assist in the
unpacking and positioning of them for listening.
Contents of the two ight cases:
•2 loudspeakers
•1 Accessories case
•1 user’s manual
•2 pairs of gloves
•8 feet
•8 spikes, recommended for carpet ooring
•4 jumpers
•1 polishing cloth
•1 impregnated polishing cloth (supplied only with
liquid gloss nish)
For unpacking, please follow the instructions described below and as
shown in the drawings:
1. Unlock / Open all six locks on the ight case cover. This
should only be done with the speaker / ight case in a hori-
zontal position.
2. Carefully lift the cover o the ight case and put it aside.
3. Be mindful of the warning signs on the drivers – excessive
pressure on the driver elements might cause damage to
them. Remove the foam plate and Accessories case from un-
der the speaker bottom as shown in drawing 3.

5. Now in an upright position, please support the speaker and
slowly roll the speaker out of the case. At this time, please
put on the gloves that you nd included in the case. Now,
with the speaker upright and out of the ight case, roll it to
the desired position in your room.

6. Replace the transport wheels with the enclosed feet. Doing
one side at a time, carefully tilt the speaker to one side and
replace the wheels with the enclosed feet, as shown in draw-
ing 6. Please retain the wheels, once removed, in the event
that repackaging is required. If you are not certain of the nal
position, we recommend keeping the speakers on wheels
during the initial set-up.
7. Remove the cloth-bag from the speaker. Please note that the
cloth-bag should always be worn with the seams outside.

4. SET-UP
Initial positioning in the room
Model Estelon Forza - Suggested room size 40-125 m2
When positioning the speakers in your room, if possible, it is desir-
able 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 tonality, realistic imaging, focus and dynamics.
The recommended minimum distance between the speaker and the
nearest reection point is 1.2 m.
A non-reective back wall will minimize imaging distortions. The dis-
tance between the back wall and the speaker should not be less than
0.6 m (1.8 ft), the distance from the tweeter to the back and side walls
must not be too similar.
Listening point: the best listening height is approx. 1 m (3 ft), while the
distance between the listener and the speakers should be similar or
longer to the distance between the two speakers.
The positioning of the speakers in the room must be symmetrical for
achieving a balanced sound stage – this is very important in a narrow
room. Expect the distance between the speakers to be approximately
2.5 – 4 m, depending on the size of the room and its reverberation
characteristics.
The recommended speaker’s direction is usually 3-7° towards the
listening position, depending on the listening room specics.

13
Wiring
When connecting the speaker to the amplier please make sure that
the amplier is in an o position.
Connect the speaker cable to the pole terminal on the back of the
speaker: speaker terminal „+“ with the amplier terminal „+“ and „-“
with „-“. For best performance we suggest using the upper pair of
connectors.
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 Forza can be bi-amped or bi-wired at your choice. Please
remove wire jumpers to be able to use the upper and lower connec-
tors separately.

Break-in period
Although your Estelon speakers had an initial break-in at the factory,
due to shipping conditions - pressure/temperature changes that they
may have incurred, the speakers will need to go through an additional
break-in process before their nal set-up.
All the mechanical and electrical connections will stabilize naturally
after playing a continuous music signal for approx. 24 hrs – e.g. use a
digital source in the repeat mode. After the initial break-in period you
can start setting-up the sound according to the recommendations
from Alfred Vassilkov.
Please note that the speakers will have reached their optimum level
of performance after playing in your system for approximately 300 hrs.
Recommendations from Alfred Vassilkov
for the set-up
The set-up of the sound consists of the balancing of many dierent
parameters: tonality, bass accuracy, focus, stage imaging, deepness
etc. This process is time consuming and depends on the listener’s ex-
perience or the qualication of the set-up specialist. Proper set-up will
maximize your Estelons’ performance.
During the nal set-up small changes may be made to the initial cho-
sen position, e.g. moving the speakers 10 cm towards the front wall,
then maybe a little bit inward and outward. Please evaluate the sound
carefully every time you make a small change in the positioning.
Then continue, making smaller changes in the positioning and eval-
uate again, until the proper position with a balanced, natural sound is
found. We suggest that you test and listen with dierent music styles
so as to avoid specic accents.

15
When changing the position of your speakers please keep in mind that:
•Close proximity to the back wall and corners will reinforce,
enhance, the bass performance, but can negatively inu-
ence the stereo image.
•A shorter distance between the two speakers, will create a
better focus and deeper imaging, but will at the same time
reduce the sound width.
•Pointing the speakers inward minimizes reections from the
side walls but has an impact on the imaging.
Once you have located the proper position replace the wheels with
the spikes included in the case.
For critical listening, each time you play the speakers, please allow 60-
90 minutes for the system to warm up for maximum performance.
WARNING! When played at excessive volume, you stand the risk
of doing damage to the drivers.

5. PRODUCT CARE
The multicoated nishes applied to Estelon speakers are considered
to be amongst the most advanced automotive nishes available. They
are extremely strong and durable. In order to assist you in maintaining
their stunning appearance, your Estelon loudspeakers come supplied,
from the factory, with special cleaning / polishing cloths. Please take
note - only dry cleaning is allowed - do not wash the speakers.
When the nature of a smudge or spot so necessitates, a soft moist
cloth may be used to gently remove smudges prior to a nal nishing
with the special cloths which accompany the speakers.
For the Liquid Gloss nish, please use only the polishing cloth included
in the ight case. Be careful not to apply the polish to the loudspeaker
drivers. The use of other materials can damage, scratch or destroy the
nish.
