In this paper the radiation mode method is used to measure the frequency response and the directivity pattern of loudspeaker systems. This method, which has been successfully applied to speaker measurement in free field conditions, is now tested in a large non-anechoic hall. Two closed box systems and a switchable bi-directive/cardioid subwoofer have been used. Each system is measured first in an anechoic chamber and then in the large hall. The radiation method is then applied to the two different measurement data sets. Results show a good agreement between both conditions. Finally, the influence of the mesh coarsening is studied.
