Bob McCarthy’s method for designing uncoupled speaker arrays can take a lot of guesswork out of using MAPP. To further streamline the process, I made a calculator that describes the relations between the parameters of speakers in uncoupled arrays.
The important parameters are the spacing of the elements (s), the splay of the elements (β), each element’s coverage (φ), the distance at which the coverage patterns of adjacent speakers overlap (D-Unity), and the distance at which three elements overlap (D-Max). For simplicity’s sake, I have made some intermediate parameters:
