Phase Alignment between Subwoofers and Mid-High Cabinets
FFT based field measurement systems have made it possible for us to do phase alignment at fixed installations as well as at live events, where every venue demands a different approach. This is particularly important these days, since mid-high boxes are often flown and subwoofers remain on the ground, meaning that phase differences at the listener location can be very significant. Given the interest in the subject, and the remarkable improvement it can bring to a system, it seems like a good idea to write an article that describes the measurement process step by step. Before doing that, however, let's go over the concept of phase.
