For a line array to work as a line array at high frequencies requires drivers to be no more (preferably less) than a wavelength apart, that is about 5/8 of an inch for 16K. Line arrays generally use special horns that emulate the response of a ribbon driver for frequencies above 1000 to 2000 Hz. Nettet1. mai 2001 · Line Arrays: Theory and Applications Authors: Mark S.

NettetPhysical theory tells us that the severity of aperture effect can be reduced by gradually reducing the amplitude of the wave to zero near the edges of the aperture. For line arrays, this means reducing the gain at the top and bottom of the array. This is the gain shading we’re talking about. It’s also called “tapering”.
