In small rooms the coupling of the low-frequency source to the room modes (eigentones) has a determining influence on the resulting low-frequency response. In practice the placement of the source is determined rather by other than acoustical factors. It is shown that an additional degree of freedom in placement and a more even excitation of the room modes can be derived by the use of dipolar low-frequency systems. Therefore, some comparative measurements of dipolar and monopolar low-frequency systems are discussed. Conclusions are drawn from the measurements carried out, outlining the advantages of dipolar low-frequency systems in small rooms.
