Several cardioid subwoofer configurations exist, but the method to be followed, as described here, is always the same. This article does not intend to assess the various configurations, but only to show the basic procedures and ease the learning process. The user should choose the most appropriate configuration for the specific application needs.

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.

Line arrays have been specially designed so when several units are combined vertically the whole system behaves as one single sound source. Generally speaking that’s what makes them different from the conventional speaker systems. But how do they work? This article develops the principles behind the line array theory for a complete understanding of what line arrays are.

DASaim™ is based on FiRmaker technology by AFMG. It is already integrated within the V3.52 GLL library of the AERO-40A, AERO-20A and AERO-20A-120 systems used in EASE Focus V3 – the acoustic simulation and modelling tool used by DAS AUDIO.

In order to achieve the desired results, DASaim™ designs custom FIR filters for each cabinet in an array, which allows unprecedented control of the overall behavior of the array.
