The effectiveness of multiple subwoofers in controlling low-frequency room modes can be improved through designing individual equalization for each of the subwoofers. The paper discusses two strategies towards equalizer design, minimizing coupling to individual modes, and minimizing the total energy radiated to the room. The frequency responses and sound field distributions obtained using these methods are compared to the results of conventional equalization and modal control only through loudspeaker placement.
