Flying a loudspeaker array overhead poses severe safety risks. The rigging hardware must be engineered with a minimum 7:1 safety factor.
If your drivers are spaced too far apart, the system will suffer from destructive interference, creating unwanted "lobes" of sound that ruin the frequency response outside of the main beam. 2. Component Selection and Cross-Over Points
Choose the drivers for the line array box, including:

The cabinet must feature a trapezoidal shape, tapering from front to back. A rear taper angle of (10 to 15 degrees total included angle) allows the boxes to be splayed tightly for long-throw coverage or angled steeply for down-fill applications. 5. Construction and Materials
Internal channels within the waveguide ensure the sound traveling from the center and the edges arrives at the mouth at the exact same millisecond. 5. Cabinet Material and Internal Bracing
Titanium or Polyimide for crisp, high-power handling. Flying a loudspeaker array overhead poses severe safety
The Ultimate Guide to 12-Inch Line Array Box Design: Engineering for Precision and Output
You must pair your compression drivers (typically 1.4-inch or 2-inch exit) with a specialized line array waveguide. These waveguides convert the spherical wave from the driver exit into a perfectly flat, coherent linear wavefront at the horn mouth.
For those looking for a comprehensive resource on 12 inch line array box design, we have created a PDF guide that covers everything you need to know. The guide includes: A rear taper angle of (10 to 15
350 mm to 380 mm (Must be kept as narrow as possible to maintain tight vertical driver coupling).
