Visaton GRAND ORGUE Lautsprecherbausatz

Bringing the deepest frequencies of large instruments, such as an organ or a double bass, is the biggest challenge for a high-end speaker.
Only a few boxes are able to reproduce the lowest register of a large church organ, and at the very least it sounds like an organ pipe.
It is also possible to present a double bass in its full volume without either sounding smoothly and inflated, or to remove the sails from the outset, only a few, unusual loudspeaker designs are reserved.
The loudspeaker boxes "Les Orgues", here in the variant GRAND ORGUE are representatives of this type.
With their eight low-tone drivers WS 25 E - 8 Ohm specially optimized for free-air operation in a folded but open sound wall, they are able to reproduce in a captivating natural and natural way without any exaggeration, but also without any weakness, frequencies up to under 20 Hz.
As a result of the elimination of a housing in the actual sense, the resonance frequency of the tweeters is not increased, but is even lowered by the special Ripol principle, which is why the orgues can emit smoothly and uncompressed very low frequencies.
However, a sufficient distance between the box and the rear wall is a prerequisite for the low-base reproduction in this principle radiating on both sides.
1 meter would be fine, for full level to the low bass area, however, 2-3 meters distance should be sought.

But the untrained and unobtrusive bass isn't everything long ago: the bass division radiating on both sides is supplemented by a line array consisting of eight oval broadband loudspeakers SL 713 - 4 Ohm.
Owing to its light paper membrane and the vibratory coil carrier, this favorable wideband is distinguished by a very natural reproduction of up to highest frequencies.
A line array has the property of radiating the sound very strongly in the direction in which the drivers are arranged.
Outside the main beam direction, large parts of the emitted sound signal are extinguished by interference.
As a result, disturbing reflections of the floor and ceiling, which are tolerable to a precise spatial representation of the musical happening, are not at all excited.
However, this bundling behavior depends directly on the wavelength of the radiated tones.
The higher the frequency and thus the smaller the wavelength, the higher the bundling measure.
In such a large array as that of the GRAND ORGUE, this would lead to extreme bundling in the high-tone range, which would no longer be practical.

In order to achieve as uniform a bundling measure as possible over the entire frequency spectrum, which in turn is important for tonal balance in the auditorium, an additional correction circuit has therefore been implemented within the array.
This ensures that, with increasing frequency, more and more power is fed to the 2nd and 3rd widebands from above, while the other 6 are always withdrawn.
The array thus in fact shortens continuously from 8 speakers to 2 speakers over the entire range of applications.
These 2 loudspeakers should be as accurate as possible to the ear height.
If the individual ear height is higher or lower than the center between the 2nd and 3rd wide bands, the box can easily be adapted to the situation by cabling the array in such a way that, for example, the 3rd and 4th loudspeakers reproduce the high tone from above. The box can thus be optimized without problems in small steps to the appropriate listening level.

The combination of these technical fines in a box leads to an absolute exceptional sound transducer, which is predestined above all, but not only for the very realistic reproduction of "natural" music.
Whether sharply torn guitar strings, crisp drumsoli, a whole symphony orchestra with the warm melting of the strings and the sizing of the brass or just the queen of the instruments, the organ, everything is reproduced extremely authentic, with a lot of dynamics and guaranteed goose bump factor.
Singinging voices, whether male or female, are also depicted with every little detail.
Instruments and voices stand on the virtual stage, everything has its natural space and its clearly defined position.
If you are looking for a loudspeaker for high-quality music, who does not want to make compromises in the field of transmission and thereby places emphasis on an exceptionally precise stage image, the GRAND ORGUE is at the heart of it.
Only a strong amplifier and sufficient wall spacing are basic requirements for the perfect function of the GRAND ORGUE.
