Connections
Kanta 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. D).
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 B2 = AC defines the ideal
loudspeaker position.
• 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 = B2 ⁄ A = 28" (72cm)] (fig. E).
