Subwoofers in Symmetrical and Asymmetrical Rooms
A theoretical study of behavior of single and multiple subwoofers, taking also geometrical and acoustical asymmetry of practical listening environments into account, is presented. The results indicate that configurations aimed at precise cancellation of individual modes have a high sensitivity to deviations from the ideal. However, with multiple subwoofers it is possible to find robust placements that both reduce the spatial variation of the sound field and the frequency variation of the response. This, however, requires loudspeaker placements where also the height of the source from the floor is varied.
