The idea behind Acoustic Lens Technology (ALT) is that the quality of listening and the tonal balance should be the same, regardless of the listening position in the room – static or dynamic. This is made possible by exploiting the unique properties of the ellipse, where the acoustic centre of the driver is placed at the lower focal point of the ellipse. All sound emitted from the driver will converge simultaneously at the upper focal point, as the distance between focal points via the perimeter is the same in all directions.
The result is the creation of a “virtual” treble driver at the upper focal point. Furthermore, the ellipse is rotated to form a three-dimensional structure, the lens, resulting in a uniform distribution of sound in the horizontal plane with 180 degrees of dispersion.
