Alsyvox Botticelli User manual

Full Range Ribbon Loudspeakers
Botticelli & Botticelli X
User’s Manual

We would like to congratulate on your purchase of ALSYVOX Botticelli!
Our mission is to make loudspeakers that can bring the musicians in your room by
giving the same emotion of a great live performance.
To reach this goal we have experienced that the use of thin diaphragm ribbons and
ribbon-planar transducers radiating sound as a dipolar (from both sides) line source is
the best approach: the sound vibration is created with all its energy as well as all the
details needed to fully respect its message. The diaphragm moves exactly like a layer
of air as it is crossed by the sound wave. This gives the sensation of transparency and
the sound does not seem to come from the speakers music is filling all our listening
room or even our house if it is an open loft with the same coherence and tonal
balance that you can experience in the classical center listening position.
All design choices were made to reach our goal making in house all the critical parts
with no cost compromise. With the typical Italian attention to style we have taken top
care both in the design and in the quality of each detail.
The company Alsyvox™ audio design
Our designer is an Italian Aerospace Engineer so Italian Design comes out naturally.
Our speakers are made by hand with love using exclusive and patented design. All
critical parts are made by us the other parts are sourced from the best worldwide
suppliers typically aesthetical parts are made in Italy electrical parts are made in
Germany everything is assembled carefully tested and signed by our chief engineer
in our laboratories in Spain.
Our designer started in 1984 by studying the interaction of a dipolar speaker with the
room walls using an array of conventional cone speakers mounted on a baffle.
A few years later he studied the technology of ribbon mid-tweeters to extend the line
source concept to higher frequencies and in 1994 he designed a ribbon loudspeaker
for RES Audio the Sky 1.
In 2005 he started using neodymium magnets for the Sky 2 to raise the sensitivity of
the ribbon speaker.
In 2009 the revolutionary ribbon-planar woofer was born. It reached the same high
sensitivity of the neodymium ribbon mid-tweeter thanks to a patented design and a
proprietary mix of design skills covering the technology to make diaphragms magnet
dimensioning push-pull magnets and steel frame design.
In 2016 he developed a compact mid-tweeter + super-tweeter unit that is
seaminglessly extending the frequency response beyond human listening threshold to
improve sound harmonics and liveliness.

Using these three transducers the result is a breathtaking coherent sound as all the
audio frequency band is covered by loudspeakers of the same height made with the
same diaphragm materials and magnets with a sensitivity of 93dB or more.
Our Technology
All our speakers are dipoles that approximate the ideal concept of a line source. This
is giving the best interaction with the room acoustics without the need for heavy room
treatment and minimum influence on sound given by the listening position.
Cross-over frequency is low enough to avoid interference and directivity problems
typically at about 700Hz between woofer and mid-tweeter and about 5000Hz between
mid-tweeter and super-tweeter. Any phase rotation is limited by the use of moderate
slope filtering.
Top quality Mundorf components are used heavily in the cross-over to respect the
information contained in the signal including the very big binding posts.
All our speakers use similar technology with push-pull ribbon (planar) woofer and an
exclusive compact unit of ribbon mid-tweeter and ribbon super-tweeter with a
frequency response well beyond the audio frequency top limit.
Extremely powerful magnets allow high sensitivity and dynamics.
Our ribbon woofers merge the typical wide surface of planar speakers with the long
stroke of cone speakers. This is making an incredibly powerful low frequency
response together with all the typical benefits of planar speakers in terms of speed
and micro-dynamics.
The push-pull design used in every transducer is creating low harmonic distortion and
the proprietary diaphragms are powered on almost all the surface to create the best
control and the reduction of all time domain distortions the most harmful to the
sound.
Heavy gauge steel is used for the structure and it is keeping the distortions related to
the frame at the minimum with the help of the considerable total weight and of our
proprietary insulating feet that keep the energy reflected by the constraint to the floor
as small as possible. All the other materials used are chosen for their vibration
damping behavior like acrylic plastic PVC and precious solid teak wood.
All these features contribute to the incredible sense of sound out of the air as opposite
to the sound out of the speakers an amazing sense of effortless power and coherence
throughout the audio spectrum so that you can listen to the music and forget about
loudspeakers and hi-fi equipment.
Our preferred standard finish is black glossy acrylic with natural teak profiles but
other colors and finishes can be made on request.

Box Content
You have received the speakers in 2 professional flight cases. If you bought Botticelli
X there is a third box for the 2 crossovers and 2 thick transparent acrylic bases to be
used with silicon feet between base and crossover.
The right speaker case shall be opened first leaving it on top of the other.
Opening the top you will see the speaker with the base laying on top of it as shown in
Photo .
You will also find a cardboard box that contains 7 bolts with 3 special double washers
1 standard M10 washer an M10 hexagon wrench 4 acetal levelers with grub screws
and nuts. If you bought Botticelli X you will also find the 6 umbilical cables to connect
the crossovers they are under the speaker.
In the other flight case (left speaker) you will find a cardboard box that contains 7
bolts with 3 special double washers 1 standard M10 washer 4 acetal levelers with
grub screws and nuts a microfiber cleaning cloth and a pair of white gloves.
Each flight case is very heavy about 150Kg each (320Lb) and you will need the help
of 3 people to move each of them and heavy duty handles on each side are provided
for them.
Of course a cart will help moving them.
Packaging
Save all packaging! We invested a significant amount of money to make a strong and
reusable packaging. If you need to transport the speakers they can be shipped safely
only in the original packaging.
You may never have to ship or move your loudspeakers but should the occasion
arise they should not be shipped in any packaging but the original.
Opening the flight case and Assembly
1. Read carefully all the instructions before you start.
2. You will need the help of 3 strong professional movers as the speaker’s flight
case is very heavy. Everyone shall wear safety shoes and gloves.
3. The 2 flight cases should be delivered in horizontal position one on top of the
other (recommended travel position). Picture 1

4. Always keep the case you are opening with the other under it or something else
with a thickness of 15-20cm to get the right height and put a thick anti-slip rug
rubber mat or carpet with no possibility to shift close to the cases were the
speaker will touch the floor when you lift it up. Picture 1 and Photo 1.
5. Open the top of the top case and remove it. The speaker is laying flat on the
lower part of the case with binding posts upward. Picture and Photo . You
can see that there is a metal sheet magnetic shield on the tweeter (only if you
received the speakers by air) this must be removed and we recommend that
you keep it in the PE bubble packaging to avoid sharp edges to be exposed.
6. Push the speaker sliding it till the edge of the speaker closer to the binding
posts (lower edge once it will be standing up) is free of the edge of the case.
Picture 3 and Photo 3, be careful to keep the light grey fabric lip
between the speaker and the aluminum edge of the flight case.
. Clear off the edge of the PE protective film. Photo 4.
8. Take one of the bases and notice that 3 special washers and 1 standard washer
are already glued in position take the others and the 7 screws and. Photo 5.
9. Prepare the base screwing in the levelers (do not use cups and balls now!) at
the 4 angles of the base and putting the screws in the holes in the position as
shown in the detail of Photo 5 and 6. This means keeping the base in vertical
position touching the floor and inserting the 4 top screws with one washer on
the outside. The other washers are used as spacer for the optimal vibration
transmission between base and speaker and are already in position. The other 3
lower screws can be inserted later.
10. Secure the base to the speaker using the 7 screws tightening them as much as
possible Photo 7.
11. Taking the speaker from the edges in a position far away from the base lift it up
with one leveler touching the floor well protected by the rug or carpet (Photo
8). This rug is not only needed to avoid damages to the floor or the leveler but
also to avoid slipping of the leveler as it would make things way more difficult
and dangerous; so be careful, no slipping shall occur. To lift the speaker

upright 2 strong people are necessary as the total force needed is about 60Kg.
Please be also very careful to avoid bending our back as you might hurt
yourself always bend your knees. Picture 4 and Photo 9
12. Once the speaker is out of the crate you can move it on the floor using a
cart or making it walk by making leverage on side levelers. You can also slide
the speaker pushing it in a low position never close to the top to avoid
deflecting the base or tipping over.
13. Once you have placed the speaker in its first trial position you can
complete the assembly of the levelers add one cup with rubber ball at a time
lifting a few centimeters on each leveler side. Make sure they are correctly in
position before you lower the side and have the speaker on the feet laying in
the cups. Here you will need the help of a friend to position the cups while you
lift the angle of the speaker’s base. Heavy working gloves are strongly
recommended to position the cups under the feet and coordination between you
and your friend: he should give commands to you to lift and lower the angle
with the leveler as he has to make sure not to leave his hands under the
leveler.
14. Now you can complete the unpacking taking out the protective film
(starting from the lower stripe) and adjust the levelers to have the speakers
perfectly vertical. Never use cutters on the film to avoid damages to the
speaker! Cotton white gloves are provided to avoid leaving finger prints on the
black acrylic surfaces.
15. Connect the speaker cables paying attention to the phase. Here we
suggest bi-wiring using identical cables for Tweeter (upper binding posts) and
Woofer (lower binding posts) but if you want to use mono-wiring you shall use
jumpers (not supplied) to connect in parallel the lower and upper binding post
be careful black with black and red with red!
16. Once both the speakers are in the first trial position and are connected to
the amplifier you can start finding the best position as described in the
Positioning Chapter.

Amplifier’s Choice
94dB effective sensitivity allows the use of low power amplifiers from 7Watt and
strong electrical and mechanical design allow the use of high power amplifiers up to
250Watt; of course quality is mandatory as this loudspeaker will cruelly show any
deficiency of the components of your system not only the amplifier but the source
and cables too.
Positioning your A SYVOX speakers
Positioning in your room requires some move and listen trial as always but the line
source dipole dispersion will help with minimal room influence on the timbre of the
sound.
All sound radiating from the speaker both directly towards the listener and in any
direction to be heard as reflected sound of the room are of the same quality and
tonally neutral; so any room will sound quite well. Of course better rooms will sound
better and each room will have its best speaker/listener positioning.
Just to start we advise you to position the speakers as symmetrically as possible
relatively to the room layout and the listening position with tweeters inside (binding
posts outside).
The speakers should be parallel to the rear wall and only later on toed in to be to find
the ideal tonal balance and image.
The front wall (behind the speakers) should be between 0.9m (3 feet) and 2.1m (7
feet) away. The best result is most of the times achieved with a distance equal
to 30-40% of the total length of the room.
Of course what is behind the speaker will highly influence the sound so avoid any
highly absorptive (open door) or highly reflective (window pane) surface.
On the other hand the sound radiated on the plane of the speakers is almost null so
no big influence from reflections of side walls and they can be quite close (not less
than 0.15m 1/2 foot).
The distance between the speakers is not very important but it should be more than
1.5m (5 feet) and about 0.3m (1 foot) less than the distance from the listener.
The wall behind the listener should be quite absorptive and at least 0.9m (3 feet)
away
Trials can be made moving the speakers by 5cm (2”) each time and slightly changing
the toe in by 1cm (1/2”) each time.
In general the best toe in is between 20cm (8”) and 25cm (10”).

Be careful: These small movements can be performed sliding the speaker on the soft
feet with a lot of care. Always apply the force close to the base and do not lift any side
to avoid that a leveler could jumps out of the cup. Always two people shall do this
one moving the speaker and the other checking the position of the cups under the
levelers. You might even push the levelers one after the other moving 1cm each time.
Be careful and do not forget to wear protective gloves.
What you should look for (listen to) is the best bass sound deep and strongly
controlled and the ideal sound stage with good focus and depth. No sound should
appear to come directly from the speakers even when the recording is totally on the
left or right.
Please do not get bored and accept a less than outstanding result here your new
speakers can a must deliver it.
Botticelli or Botticelli X
If you bought Botticelli it is possible to upgrade to Botticelli X buying the external
crossovers. There is a switch in the back below the 4 binding posts. Switch UP
enables the internal crossover and this is the position that must be used with
Botticelli, switch down bypasses the internal crossover and this is then position
that must be used with Botticelli X. (Photo 10)
In the case of Botticelli X there are 3 umbilical cables that connect the external
crossover of each channel to its speaker to connect them we use 3 Neutrik®
SpeakOn® connectors. The connector closer to the woofer (internal) is the woofer
connector (W) center connector is for mid-tweeter (MDTW) and external
connector is for super-tweeter (STW).

Cleaning
Do not use strong chemicals paint thinners acetone alcohol ammonia or vacuum
cleaner to clean the speakers!
Acrylic plastics cover may be cleaned by use of the included microfiber cloth (very
slightly humid if necessary). In case of need a mild detergent like hand washing liquid
soap can be used.
Never apply pressure when cleaning!
Very light scratches can be eliminated by white car polish and microfiber cloth deeper
scratches will need a professional polishing operation.
