Gradient Evidence - Waveguide and Point Source Design

A BRIEF DESCRIPTION OF TECHNOLOGIES
· acoustic waveguide at high frequencies
The aluminium 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.
