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.
