Loudspeaker equalization is an essential technique in audio reproduction. Conventional equalization schemes focus on dealing with the axial impulse response, and thus cannot provide sufficient off-axis equalization, which is required in near-sound-field applications. A new loudspeaker equalizer is proposed. It addresses this problem and the problem of binaural perceptual difference. Equalizer designs for multiuser and/or multiposition environments are also briefly discussed. These methods have the potential of being applied in practice in the implementation of automobile, TV, or desktop loudspeaker systems.
