Three Major Types of Dispersion In the field of loudspeaker design, it is a known fact that as Historically, most attempts to achieve smooth dispersion the sound wave becomes progressively smaller than the from large flat-panel transducers resulted in trade-offs. transducer producing it, the dispersion of that wave After exhaustive testing of these different solution attempts, becomes more and more narrow, or directional. This fact we found an elegantly simple, yet very difficult to execute occu

Today, most of us take the wonders of sound reproduction for granted. Bell Laboratory’s electrostat was something to behold. This enormous bipolar speaker was as big as a door.

The test instrument needed an extremely accurate the KLH 9. Due to the large size of the KLH 9, it did not speaker, but Janszen found that the cone speakers of the period were too nonlinear in phase and amplitude response have as many limitations as the Quad.
