Operating principle
The linear arrangement of transducers creates a much better acoustic impression
than conventional loudspeakers when carefully tuned. This arrangement of the
transducers creates a cylindrical wave in the near field, whereas in the far field a
spherical wave develops. The result is a stronger orientation of the sound signal in
the vertical direction in space.
This bundling of the sound signal means that less sound is emitted to the floor and
ceiling. Particularly in rooms with a high sound pressure level, there are fewer
unwanted reflections, which disturb the sound image sensitively and unpleasantly. In
addition to the high quality of the sound transducers, the prevention of reflection
leads to a crystal clear acoustic room impression over the full frequency range.
A prerequisite for optimum hearing quality with this arrangement of the transducers
is a sufficient distance of the listener from the source. The listening distance should
be at least 2 m
6 Setting up and positioning the speakers
The loudspeakers should be positioned at a distance of 1.5 to 3 m in the two corners
of an equilateral triangle, the third corner forms the listening area. The distance to
the side walls must be at least 0.5 m and the listening distance at least 2 m.
The operating position of the speaker is upright and should therefore be firmly placed
on the floor. You can use the supplied supporting feet for this. However, you can also
exchange these for spikes, for which M8 threads are provided on the base of the
speaker. Unscrew the feet and exchange them for the spikes of your choice. It is
advisable to attach and adjust the spikes only after the optimum position for the
speaker is found. Be careful, direct contact with the floor can cause ugly scratches,
which can be prevented by using a soft washer, for example. When replacing the
speaker, make sure that it does not tip over and get help to overcome the weight of
the speakers.
If the cabinet does not stand firmly and wobble-free on the floor, you can adjust the
feet or spikes until the speaker stands firmly on the floor. Then tighten the lock nuts
on the cabinet.
There is a further optimisation for improving the sound quality of the speaker.
For both stereo and home theater installations, try to set up the environment
acoustically similar for all speakers. If one speaker is placed near an acoustically hard,
bare wall, and the other is surrounded by cushioning material such as upholstery and
curtains, the sound quality will decrease and the overall acoustic impression will be
distorted.
