... fluctuations over the directivity index of the loudspeaker system as we move from the medium to the tweeter. We also remind that the in-phase behavior of the two filter banks used justifies the similarity ... judicious adjustment of Lagrange mul- tipliers. The proposed method was then applied to enhance the control of the directivity behavior of a two-way coax...
