A generalized approach to determining the position and size of "narrow" phase-plug channels is presented that is applicable to compression drivers with radiating diaphragms of arbitrary geometry. In addition, it is demonstrated that by carefully shaping the compression cavity according to the diaphragm motion then optimal behavior results. FEM computed examples are presented demonstrating the method for the case of a conical diaphragm geometry.
