Re: 2 Box Subwoofer ArrayYou can check your work by inverting polarity of the boxes, to purposefully have the cancellation in the audience rather than on stage (if tuning from FOH area), adjust the delay times until you get as close to full cancellation as possible. When you find the best delay time, invert polarities to put cancellation back towards stage. Agreed on choosing 60-70Hz center. This gets iffy if the subs are near a boundary, such as backed against a wall.
