[QUOTE="andrew gissing, post: 13114, member: 75"] I don't think there is a perfect answer to this question because of physics; but would like to ask some advice. The key question I have is where do you take your measurement from ? There is a triangle between where the line array (A), subs (B) and mic position (C). Now A & B are not moving, but you can put your mic anywhere; and because the distance between A-C, B-C will change, this means the time and phase alignment will be different. I'm aware of wanting to match the phase traces between the mains and subs in the crossover region. So you've got to pick a point which I guess is a decent approximation for most of the audience ? Anyone, anyone.... Bueller ? Andrew [/QUOTE]
