Special precautions regarding the
Beryllium dome tweeter
In its solid form, Beryllium is harmless.
However, due to its nature, certain
special precautions should be
observed to avoid exposure to
unnecessary ris .
• Under no circumstances should the
Beryllium dome be subjected to any
form of abrasive action. To ensure
no accidental damage to the tweeter
dome it is advised to carefully replace
the magnetic protection grille.
• In the unli ely case of damage to
the dome, of any form, the supplied
piece of adhesive tape should be
immediately used to seal the whole
front surface of the tweeter. The
protective cover should then be
replaced and also taped securely in
place. You should then inform the
dealer from whom you purchased
the product so that the tweeter can
be removed by a professional and
returned to the product distributor for
replacement.
• If the dome is bro en in any
way giving rise to loose particles
of Beryllium, these should be
carefully collected with the use of an
adhesive tape and sealed in a zip-top
bag to be returned with the tweeter.

Breaking-in period
The drivers used in the Electra Be line
are made up of complex mechanical
elements and require an adaptation
period before they deliver their full
potential. They must get adapted
to the temperature and humidity
conditions of their environment. This
brea ing-in period depends upon
the encountered conditions and
can last several wee s. In order to
shorten this period, we advise you to
let your spea er operate for about
twenty hours at medium level, playing
standard music programs, but with
a large amount of bass. Once the
components of the loudspea er are
completely stabilized, it is possible to
enjoy the real performance of your
spea ers.
Magnetic disturbance
The Electra Be line spea ers generate
a magnetic lea age that may interfere
with other sensitive household
appliances. It is strongly advised not to
place the spea ers closer than 50cm
to your TV screen. Frame geometry
as well as colours can be severely
distorted by a magnetic field if the
loudspea er is placed too close to the
cathode ray tube.
Generally, every sensitive element
(audio tapes, video tapes, magnetic
data storages, projector and CRTS
overhead-projector) should not be
placed too close to non-shielded
loudspea ers.
User precautions
All the products in the Electra Be
range are lacquered in order to
offer a resistant cabinet surface
and to ma e the up eep easy.
We recommend the use of a dry cloth
to dust your pair of loudspea ers. If
the loudspea er is stained, then use a
damp cloth.
Never use any solvents, detergents,
alcohol or corrosive products,
scrappers or scouring powder to clean
the surface of the loudspea er. Avoid
placing the loudspea ers near a heat
source.

Running-in period
The drivers used in the loudspea er
are complex mechanical devices
and require an run-in period before
they deliver their best performance.
They must get adapted to the tem-
perature and humidity conditions of
their environment. This brea ing-in
period depends on the encountered
conditions and can last several wee s.
In order to shorten this period, we
advise you to let your loudspea ers
operate for about twenty hours at
medium level, playing standard musi-
cal programmes, but with a large
amount of bass.
Once the components of the loud-
spea ers are completely stabilized, it is
possible to enjoy the real performance
of your loudspea ers.

Positioning
The loudspea ers have been en-
gineered to deliver the most faithful
sound reproduction, whether they are
used for music or home cinema. In
order to enhance their performance,
to guarantee a high quality of
listening, sound image and tone
balance, it is important to note the
following basic rules.
The listening area must be located
at the summit of an equilateral
triangle whose two other points
of insertion are determined by the
position of each spea er. Nevertheless
it is possible to modify these distances
to find an ideal compromise according
to the particular disposition of the
room (fig. A).
Each loudspeaker must be placed
at the same height and on the
same floor plan. The tweeter should
be at the same height as the listener’s
ear, when the listener is in their usual
listening area (fig. B).
Avoid placing the loudspeakers
too close to the room’s corners or
walls. This will induce some unwanted
room resonance and artificially
increase bass response. On the
contrary, if the bass level proves to be
insufficient, it is possible to move the
spea ers closer to the walls to adjust
the bass level (fig. C).
Optimization
To please the perfectionists, we shall
give an optimum positioning formula :
if A is the distance from the boomer
centre to the closest wall (floor or
wall), B the intermediate distance and
C the longest distance (A<B<C), the
relation B2=AC determines the ideal
position of the spea ers (fig. D).
• Example 1
The boomer centre is 60cm (24”) from
the floor (B=60cm) (mini spea er on
a foot), standing 50cm (20”) from
the bac wall (A=50cm), the
side wall will be ideally 72cm (28”)
(C=B2 ⁄ A=72cm).
• Example 2
the boomer centre is 30cm (12”) from
the floor (column spea er) (A=30cm),
1m (39”) from the bac wall (C=1m),
the clearance with respect to the side
walls will be B=√AC=54.7cm (22”).
Important
Stylish driver protective caps conjoined
to the loudspea er. Do not remove for
optimized performances.
Connections
The Profile input soc ets ensure
reliable multipurpose connections for
stripped cables as well as for plugs.
It is imperative to respect the connector
polarity of both the loudspea er
and amplifier. The positive terminal
“+” must be connected to the
corresponding (matching) amplifier’s
terminal and the negative terminal
“-“ to the negative terminal (fig. E).
Stereo image, soundstaging and
bass perception would be seriously
compromised if these conditions were
not respected.
User instructions
The sound rendition of the loudspea er
depends strongly upon the listening
room’s acoustics, the place of the
loudspea ers and the listening area.
These factors can be modified in
order to correct or enhance a desired
effect.
Should the soundstage be im-
precise or not centred, try to move
the loudspea ers closer to each other.
Harsh or aggressive sound means
that your listening room is probably
too reflective. Try to use any absorbing
materials (such as tapestries, sofa,
wall coverings, curtains…) combined
with reflective materials to absorb or
diffuse resonances.
Should the sound be “flat”
or muffled, there are too many
absorbing materials in the listening
room. The sound appears to be
closed-in, with a narrow stereophonic
image. Try to find a better compromise
between absorbing and reflective
materials within your listening room.
Generally the wall to the rear of
the spea ers should be made up of
reflective materials so that the sound
image exhibits satisfying volume and
width. On the contrary the wall on
the rear of the listener should be
absorbing in order to avoid reflections
damaging the perception of the
stereo soundstage. These reflections
may limit the impression of depth of
the sound image. Furniture, such as
boo shelves should be ideally placed
along the side walls in order to diffuse
sound waves and to prevent some
frequencies from being amplified,
especially in vocal range (it removes
“flutter echo”).

Accessories
Floorstanding loud-spea er systems
include four decoupling spi es (cones)
and should be screwed, if necessary,
into the four metal inserts situated on
the base of the loudspea er. These
spi es ensure a better stability for
floorstanding spea ers, particularly
if the floor is not perfectly flat and
smooth. This stability improves clarity
in bass and midrange by decoupling
the system from the floor and thus
reducing floor-born resonances.This
required stability allows the energy
delivered by the woofer’s membrane
to be integrally converted into sound.
The enclosed spi es are adjustable
in height. After having adjusted the
height of the spi es, don’t forget to
loc them with the loc nut.
When the use of the spi es proves to
be necessary, we advise you to place
a piece of metal (such as a coin)
between the floor and the spi e in
order to avoid scratching a tiled floor.
Boo shelf spea ers can be placed on
an optional stand specially developed
for them.
User precautions
The tweeter is made up of a relatively
soft aluminum/magnesium alloy and
has a “shape memory” that enables
it to rapidly ta e its initial shape again
after slight impacts. However we
advise you not to remove the spea er
grille in order to eep the dome
protected. If the dome surface is
damaged, tweeter performance may
be compromised.
As the loudspea er’s covering
materials are strong, scratch and stain-
resistant, maintenance is easy and
consists only in cleaning the covering
with a dry cloth. If the enclosure is
stained, we simply recommend the
use of a damp cloth.
Never use any solvents, detergents,
alcohol or corrosive products, scrap-
pers or scouring powder to clean the
surface of the loudspea er.
Avoid placing the loudspea ers near
a heat source.
About amplifiers
Contrary to what one might thin , it
is not a too powerful amplifier that
might damage a loudspea er, but
rather a lac of power. Actually if the
output level of the amplifier is too high
it will saturate and distort which will
irremediably damage the tweeter.
The power handling and frequency
response of the loudspea ers is good
enough to highlight the qualities or
wea points of the amplifiers they are
combined with. Let your retailer help
you ma e the right choice, matching
your personal taste and budget.
Cable
Don’t underestimate the importance
of the cable: ma e sure you chose the
appropriate section and length. Let
your retailer advise you.
Conditions of guarantee
All Focal loudspea ers are covered
by guarantee drawn up by the official
Focal distributor in your country.
Your distributor can provide all
details concerning the conditions of
guarantee. Guarantee cover extends
at least to that granted by the legal
guarantee in force in the country
where the original purchase invoice
was issued.
