This flying system is made up of four SR-A12L speakers, two SR-A12S speakers, and one SR-A18B speaker.
To transmit sound over long distances, the four SR-A12Ls are given overlapping angles of 4, 2, and 1 degree,
resulting in a total vertical directivity angle of 43 degrees. The overlapping angle can be adjusted by means of
the Joint Plates used to join the speakers. The horizontal directivity angle is fixed at 90 degrees.
As can be seen in the accompanying figure, the overlapping angle equals the rear-opening angle between
enclosures.
[Example] To adjust the sound radiation-overlapping angle to 5 degrees, set the rear-opening angle between
enclosures to 5 degrees.
No sound overlapping angle is created if speakers are joined without space provided between enclosures.
