The A6-EVO is a compact but extremely powerful floor standing
loudspeaker designed to provide a natural and smooth sound
reproduction: it's simply the best speaker of this size we have
ever made and it's distinctive in its beautiful slim diamond
shaped design.
The new 12 cm SEAS treated paper front mid-woofer drivers
feature massive magnets to control power guaranteeing ultra-
extended bass response while offering a higher efficiency for
maximum resolution.
To provide exceptionally fast transient response and retain full
natural music reproduction, the two mid-bass drivers have a
12dB/Octave set up at 2000Hz/60Hz range, where the 15cm
SEAS ultra rigid woven polypropylene internal subwoofer driver
kicks in.
The subwoofer is located in a separate sealed chamber at the
bottom of the speaker and features a dedicated crossover
network and bass reflex port faced to the floor that with the
help of its special designed wooden stand allows no critical
room positioning and perfect bass power impact.
The subwoofer driver is realized through metal injection
moulding to create a supporting structure specifically designed
for powerful bass reflex speakers and combined with a special
spider ring and ultra-elastic suspensions with insertion cuts to
achieve greater extension and power but also finer details.
The custom 1” silk dome tweeter is tuned to match the speaker
shape and features an rigid aluminum flange to deliver crystal
clear high-frequencies with full power.
The cabinet features two diamond shaped side panels with
aluminum inserts thus resulting in a stronger, more rigid
structure to enhance power control.
The speaker lays on a solid and elegant wooden stand
with a bottom bass reflex port.
The crossover components are exclusively made by Mundorf
and Clarity: no compromises have been made on the design
and only top quality parts have been chosen.

CONNECTING THE SPEAKERS

Identifying the ideal sound/acoustic room to play an audio system well is not that strictly related to the
proportional dimensions of the rooms as many audiophiles believe.
The sound played through an audio system is just “Energy diffused in a closed environment” that is all
absorbed, reflected and dispersed.
The loudspeaker position is the most important aspect because managing the reflections is a key factor to get
the best sound. The first two reflections are crucial, after them the energy of the reflection starts being lower
and does not particularly affect the sound performance.
The first reflection creates a 25m/s delay. Such delay is not favorable because it creates a disturb overwhelming
the sound while the delay in between 40 and 80m/s creates what is called ambience.
Therefore it is very important to reduce the first reflection keeping the speaker as far as possible from the side
walls and using some carpets on the floor in front of them is advisable.
A symmetrical position of the speakers in the room, having the same distance from the side and rear walls is also
very important and should be implemented when possible. The better the positioning the better the focus and the
sound stage will be.
WALL MATERIAL
Generally, most of the walls are thick therefore there is the best bass extension control as well as good acoustic
isolation.
Dry walls vibrate quite a bit, therefore they are usually not favorable or should be treated accordingly.
CEILING
The higher the better. The ideal works between 250 and 360cm having the same regular height.
The vaulted ceiling is quite critical because it works like a magnifier lens increasing the power in specific areas.
In case of an attic where typically the ceiling slopes down it is better to position the speakers closer to the lower
ceiling and place the listening point in the higher ceiling area.
FLOOR
Marble floors are the worst because they are extremely reflecting but even the all carpet floors don’t work well
because they absorb indiscriminately
The best option are wooden floors. In any case, all floors can be easily corrected with a 2/4cm thick carpet placed
in front of the speakers.
SIDE WALLS
Covering the side walls with a carpet is wrong but leaving them naked is not the ideal solution either. Pictures with
frames on the walls are ok if they come without glass protection and are placed symmetrically on both sides of the
speakers. Eventually some small specific traps could be a good solutions.

REAR WALL
The rear wall does not need to be symmetrical like the side walls but some additional acoustic treatment will be able to diffract
the energy of the sound wave which is important to get good results.
A traditional library with books and records is a very good “no cost” solution.
OPPOSITE WALL
The wall opposite of the stereo system is not that critical. If it is too close to the listening point itself it would be better covering
it with some absorbing material or with a thick curtain.
WINDOWS AND DOORS
They always vibrate. It would be better to not have them situated in the room’s corners or in the middle of the side walls.
Treating them with absorbing material could be good but they also must be well closed not waving. Having a door behind the
listening point could work fine once opened.
Curtains in front of the windows should be light to avoid stopping too much energy, except for the optional ones behind the
listening point.
FURNITURE
Ideally, avoid using big furniture with glass/many doors. Open shelf furniture is the best.
If possible, avoid placing the table in between the speakers and the listening point because tables tend to reflect
heavily the high and mid-frequencies.
AUDIO RACKS
Though the best position of audio racks usually is not in the middle of the speakers, some special racks such like the Gold Note
Galileo can beπlaced there because its special all curved shape helps diffracting the sound waves very well. If you are using
standard racks placed in the middle of the speakers, it is preferable to have rather small ones which enhance a better sound
focus.
SUBWOOFER
A general thinking believes the subwoofer does not have any direct emission of sound so the position is not important.
In fact, the energy of the waves generated by the subwoofer creates a sound stage which follows rules similar to the full
range speakers therefore the same rules should be applied to it as well.

SPEAKER POSITIONING

WIDER STEREO SOUND STAGE SPEAKER POSITION
(for some instrumental music, symphonic orchestra, etc.)
WIDE STEREO IMAGE SPEAKER POSITION
(for some instrument music, synfonic orcherstra etc.)
Listening Point
• The distance of both the speakers to the listening point should be the same
• The distance between both the speakers and the side walls should be the same
• The distance between both the speakers and the rear wall should be the same
The more distance there is between the speakers the wider the sound stage will get but less focus will the obtained.
To balance the focus, the speakers can be directed to the listening point as indicated in the images of the pages 9
and 10 of this manual.

SPEAKER POSITIONING

NARROWER STEREO SOUND STAGE SPEAKER POSITION
(Optionally for solo instrument music like piano, guitar and voice etc.)
WIDE STEREO IMAGE SPEAKER POSITION
(for some instrument music, synfonic orcherstra etc.)
Listening Point
The closer the two speakers stand the better the focus but worse the wide realistic sound stage.
