AB  - The concept and advantages of Progressive Directivity Array (PDA) was introduced at the ISEAT 2015 convention. The primary advantage of the PDA compared to conventional approaches such as line-array or point-source speakers is that the intended tonality can be achieved regardless of the room conditions (shape and material) with consistency throughout the target audience area not just for a single listening point. The study clearly indicates that precise coverage control to match the audience area with continuity of the sound source without gaps between modules are two crucial elements to achieve the primary objective. In this paper, adaptation of the PDA concept to the real product as a modular approach is described with performance of the product followed by application of the products to real world examples.
