AB  - In this paper the ”radiation mode” (RM) method is applied to the measurement of the frequency response and directivity pattern of two loudspeaker systems. This approach is based on solving the discretized Helmholtz equation on the source boundaries to obtain an efficient expansion suitable to represent any field radiated by a source. Bookshelf and column systems have been tested. Results obtained with the proposed method are then compared to the ones given by two other methods: measurement in an anechoic room and boundary element computation based on the scanning of the membrane velocity. Results show a good agreement between the different methods. Pros and cons of the different approaches are then discussed as well as the possibility to use the ”radiation mode” method in non-anechoic rooms.
