able to adapt the circular section of the
compression driver to a rectangular section,
getting on-phase waves at the end of the guide.
This flat wavefront is ideal for vertical
configurations.

Sound engineers use line arrays to obtain narrow directivities on the vertical plane.
For configurations with many cabinets (big height) and at high frequencies it is not
unusual to achieve narrow angles- in some cases they may be grade fractions. This
can be useful in venues where both a high sound pressure level and long throw are
required; nevertheless, this means less coverage of the audience area.
It is sometimes useful to achieve an asymmetrical coverage pattern on the vertical
plane, which can be obtained by aiming some of the cabinets through their hinging
points. We are now ready to define the last two criteria of "arrayability".
4) For curved arrays, the tilt angles should vary in inverse proportion to the listener
distance (this is geometrically equivalent to shaping variable curvature arrays to
provide equal spacing of individual element impact zones).
5) There are limits given the vertical size of each cabinet and their relative tilt angles.
In our case the maximum tilt angle (between cabinets) is 6º.
