Bose Panaray MA12 Landasan Teknis & Diskusi
Figure 7. As we look down on the plane-wave source, we see that the
sound is confined to the width of the source (top right). If we look from
the side, the sound is confined to the height of the source (bottom
right).
Again looking down on the source, now imagine that the horizontal dimension of the
source (currently one meter) was reduced to only a few centimeters. The result is shown in
Figure 8. The vertical radiation pattern does not change because the source retains the same
vertical dimension (bottom of figure). The horizontal radiation pattern (top of figure) changes
drastically because the much smaller source size corresponds to a much wider radiation
pattern. (Note that the same physics explain why a 2" (5 cm) driver has a much wider
radiation angle than a 12" (31 cm) driver, assuming both are operating at the same
frequency).
