Room acoustic characteristics, such as reflections and reverberation, often change the performance of speaker systems in a room. It has always been challenging to maintain the tonal balance of a single speaker module when multiple modules are used to form speaker arrays. Both phenomena are unique to sound reinforcement speakers and are mainly determined by a combination of the radiation characteristics of an individual speaker module and the interactions between modules, known as arrayability. First, this study reviews the performance of conventional speaker systems. Next, the acoustic characteristics of speaker modules desired for forming an ideal speaker array are discussed. A new category of speaker system, the Progressive Directivity Array, is introduced to realize the theory as a practical solution.
