Dispersion Interactions
Controlled Horizontal Dispersion
Your CLX’s launch a 30 degree horizontal dispersion pat- tern. This horizontal dispersion field gives a choice of good seats for the performance while minimizing interactions with side walls (see figure 11). Make sure both speakers stand exactly at the same vertical angle, otherwise the image can be skewed or poorly defined. The wave launch of both speakers is extremely accurate in both the time and spectral domain. Consequently, small refined adjust- ments can result in noticeable sonic improvements.
Controlled Vertical Dispersion
As you can see from the illustrations, your CLX speakers project a controlled dispersion pattern (see figure 12). Each CLX is a 57 inch line source beginning 9 inches above the base. This vertical dispersion profile minimizes interac- tions with the floor and the ceiling.
Three Major Types of Dispersion
It is a known fact that as the sound wave becomes pro- gressively smaller than the transducer producing it, the dispersion of that wave becomes more and more narrow, or directional. This fact occurs as long as the transducer is a flat surface. Large flat panel speakers exhibit venetian blind effects due to this phenomenon. This is one reason why many manufacturers opt for small drivers (i.e. tweeters and midrange) to approximate what is known as a point source wave launch.
Historically, most attempts to achieve smooth dispersion from large flat panel transducers resulted in
