A BRIEF DESCRIPTION OF TECHNOLOGIES
· acoustic waveguide at high frequencies
The Mg-Al dome tweeter placed at the apex of the cone uses
midrange diaphragm as a waveguide to control treble
dispersion. The resulting radiation pattern at high frequencies is
therefore very similar to that of the cardioid midrange. Of
course the tweeter is equipped with a voice coil/ magnet system
of its own.
· a point source at mid & high frequencies
A point source is generally accepted as an ideal sound source.
It enables excellent frequency response and phase properties
over a wide listening window. The result of this will be stable
and accurate stereo picture with good three dimensionality. The
quality of a recording will be easily discovered.
