The DSP1501 Phased Array Column Loudspeaker utilizes advanced electronic and digital signal processing (DSP) technology to precisely control the main beam radiation direction. Unlike conventional fixed-directivity column speakers, the DSP1501 enables flexible adjustment of the loudspeaker's vertical directivity and radiation angle through an intuitive web-based control interface.
