Thank you for purchasing a Focal product. Welcome to our High-Fidelity world. Innovation, tradition, excellence and pleasure are our
values; our one and only aim is to bring you a sound that is rich, pure and true. To get the most out of your product, we recommend
that you read the instructions in this booklet, then store it in a safe place to refer to in the future.
Connections
Sopra connectors provide reliable, multi-purpose contacts for stripped cables (up to 4mm diameter), fork terminals or banana
connectors. It is imperative to respect the connector polarity of both the loudspeaker and the amplifier. The connector marked "+"
must be connected to the positive output on the amplifier and the connector marked "-" must be connected to the negative terminal
(fig. A). Stereo image and bass perception would be seriously compromised if these conditions are not respected. Choose good
quality cables with a cross-section appropriate to their length: your retailer will be able to advise you.
Positioning
These loudspeakers have been designed to deliver the most faithful reproduction of all kinds of music or home cinema programmes.
Nonetheless, we recommend following these simple rules to optimise their performance and to guarantee good tonal balance and a
realistic sound image.
The loudspeakers should be positioned symmetrically, facing the listening area, ideally forming an equilateral triangle with it. However,
these distances may be adjusted to find the ideal compromise according to the design of your interior (fig. B).
The loudspeakers should be positioned at the same height, in the same horizontal plane. Ideally, the tweeter should be positioned at
the same height as the listener's ears in the usual listening position (fig. C).
Do not position your loudspeakers too close to a corner of the room and do not place them too close to a wall. This will induce some
unwanted room resonance and artificially increase bass response. On the other hand, if the bass level is considered to be insufficient,
you could try moving the loudspeakers nearer a wall to re-balance the bass level (fig. E).
Optimisation
For perfectionists, here is a formula for optimal positioning:
If A is the distance from the centre of the woofer to the nearest floor or wall, B is the distance to the next closest floor or wall, and C is
the greatest distance (A < B < C), the equation B
• Example:
If the centre of the woofer is 20" (50cm) away from the rear wall (A) and 24" (60cm) above the floor (B), then the side wall will be
ideally 28" (72cm) away [C = B
Recommendations for use
The behaviour of the loudspeakers depends on the acoustics of the listening room, on the correct positioning of the loudspeakers
within the room, and on the position of the listener.
It is possible to tweak each of these parameters to obtain or improve a desired effect.
Stereo perception is imprecise and poorly centred: try moving the loudspeakers closer together and/or have them facing the
listening point.
The sound is harsh, aggressive: the acoustics of your listening room are probably too reverberant. Consider using sound-
absorbing materials (carpets, upholstered furniture, tapestries, curtains, etc.) and sound-reflecting materials (furniture) to absorb
or diffuse resonance.
The sound is "flat", strangled: there are too many sound-absorbing materials in the room, the sound is soaked up, it has no relief.
Look for the best compromise between sound-absorbing and sound-reflecting materials in your room.
