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
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 B =AC determines the ideal position of

the speakers (fig. D).
• Example 1:
The woofer centre is 60cm (24") from the floor (B=60cm) (mini speaker on a foot), standing 50cm (20") from
the back wall (A=50cm), the side wall will be ideally 72cm (28") (C=B ⁄ A=72cm).

• Example 2:
the woofer centre is 30cm (12") from the floor (column speaker) (A=30cm), 1m (39") from the back wall (C=1m), the clearance with
respect to the side walls will be B=√AC=54.7cm (22").
Connections
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 conditions were not respected.
