AB  - Most of compression drivers have phasing plugs with annular slots. Existing theories give recommendations for positioning of annular slots to suppress air resonances in compression chamber. However, interaction of diaphragm’s mechanical resonances with the compression chamber’s air resonances makes the problem very complex and a general theoretical solution hardly exists. New approach, based on certain empirical assumptions, is proposed and explained. New phasing plugs have slots of a “meandering” shape that provide effective “averaging” of high-frequency acoustical signal received from different parts of compression chamber. The method is applicable to drivers having domes, cones, and annular diaphragms. Other aspects of the design such as efficiency, compression ratio, and difference between air resonances in dome and annular compression chambers are discussed.
