Positioning
The loudspeakers have been engineered 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 speaker. 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 speakers closer to the walls to adjust the bass level . (fig.C)
Optimization
For perfectionist people, we will give an optimum positioning rule: If A is the determined distance between the floor
and the middle of the two woofers (X), C is the distance between X and the side or back wall, then the distance B is
found with the
equation B2 = AC.
Example: The woofer center is at 50cm from the floor (A= 50cm). We decide that the distance between X and the
side wall will be 72cm (C = 72cm), the loudspeaker will then have to be placed at 60cm from the back wall. B2= 50 x
72 = 3600 ( ). B = √3600 = 60cm.fig.D
Connections
The Electra Be II input sockets ensure reliable multipurpose connections for stripped cables as well as for plugs.
It is imperative to respect the connector polarity of both the loudspeaker and amplifier. The positive terminal
“+must be connected to the corresponding (matching) amplifier’s terminal and the negative terminal “-“ to the
negative terminal . Stereo image, soundstaging and bass perception would be seriously compromised if these (fig.E)
conditions were not respected.
Running-in period
The drivers used in the loudspeaker are complex mechanical devices and require run-in period before they deliver
their best performance. They must get adapted to the tem-perature and humidity conditions of their environment.
This breaking-in period depends on the encountered conditions and can last several weeks. In order to shorten
this period, we advise you to let your loudspeakers operate for about twenty hours at medium level, playing standard
musical programmes, but with a large amount of bass.
Once the components of the loud-speakers are completely stabilized, it is possible to enjoy the real performance of
your loudspeakers.
