What do the letters IDS stand for?
They describe the outstanding features of the system: imaging, depth and spaciousness. The goal was to create a system that would faithfully reveal these listening. Imaging is the ability of a speaker to accurately reproduce stereo information so that the listener is able to locate instruments as they were positioned in the actual performance or as they were mixed. Depth is the illusion that the instruments are located at various distances behind the plane formed by the two speakers. Spaciousness is the illusion of size, either natural or artificial, giving the impression of a very large room or enclosure having reflections with various amplitudes, time delays or frequency shifts. The synthesized spaciousness used today in popular and electronic music is extremely appealing.
