[QUOTE="Uwe Riemer, post: 71969, member: 394"] Re: Trap Boxes? Yes, you are missing alot, so I recommend that you read in following order: Mr McCarthys book Mr Uredas papers on line arrays Mr Heils original AES paper on line arrays and there is no way that one could sum up this knowledge in a forum post without creating more misconception. Nethertheless I will point out three things: a) interference is not equal to comb filter, destructive interference is b) a single line array element does not have very narrow vertical coverage, actually the vertical coverage is narrowing with rising frequency, how much is a design decision and will define the maximum possible splay angle between two elements. c) how many elements of a line array interfere at a given listening point is a result of the directivity and the splay angle of the elements, the phase difference defines if interference is constructive or destructive Uwe [/QUOTE]
