DISPERSION INTERACTIONS Controlled Horizontal Dispersion Three Major Types of Dispersion In the field of loudspeaker design, it is a known fact that as Your Scenarios launch a 30 degree dispersion pattern when the sound wave becomes progressively smaller than the viewed from above. This horizontal dispersion field gives a transducer producing it, the dispersion of that wave choice of good seats for the performance while minimizing becomes more and more narrow, or directional. This fact interact

Figure 89. As can be seen here, point source concepts invite a great deal of room interaction. While delivering good frequency response to a large listening audience, imaging is consequently confused and blurred. Figure 1011. Even though they suffer from venetian blind effect, angled multiple panel speakers can deliver good imaging, but only to specific spots in the listening area. Figure 1112. A controlled 30-degree cylindrical wave-front, which is a MartinLogan exclusive, offers optimal s

In 1947, Arthur Janszen, a young Naval engineer, took part to around 70 watts. As a result, many people continued in a research project for the Navy. The Navy was interested to use box speakers with cones. in developing a better instrument for testing microphone arrays. The test instrument needed an extremely accurate In the early 1960s Arthur Janszen joined forces with the speaker, but Janszen found that the cone speakers of the KLH loudspeaker company, and together they introduced period were
