Finite Baffle Dipole Speakers with Electrodynamic Drivers: Design, Implementation, Measurements, and an Experiment of Digital Equalization

Dipole loudspeakers are widespread and are known to merit from the benefits of figure-eight polar response throughout the audio spectrum. Figure-eight room loading creates a weaker early reflections field and a stronger reverberation field, both qualities adding to the creation of more realistic stereo reproduction. Moreover, the use of standard electrodynamic loudspeakers for building dipole loudspeakers is cost effective and an easy interface with amplifiers (high sensitivity and impedance). Implementation strategies, computer modeling, and measurement tips are both presented and analyzed. Additionally, the use of digital equalization using a proprietary D.E.A.S. system with dipole loudspeakers is also discussed and analyzed.
