[QUOTE="Phil Graham, post: 107216, member: 430"] Re: Line arrays and inter-element angles. Brandon, In addition to Bennett's excellent reply, the crux of the issue is this: At high frequencies you can make a much more narrow array beam, and or steep array level gradient than at low and mid frequencies. The shorter the array, the more severe this difference in behavior is. The directivity balloon at lower frequencies, even with long lines, is "squishy" and broader than the high frequency array directivity. Because of this, if you want to tailor the array for consistent magnitude response throughout the room, you're going to have to accept a gradient in level from front to back. This gradient will be dictated by the relative level variations at each point along the listening plane as dictated by the overall directivity (or lack thereof) of the array at the bottom end of its coverage frequencies.
