Review and Analysis of the Dinaburg C2S™ Alignment
Review and Analysis of the Dinaburg C2S™ Alignment -
Presented at the 155th Convention of the AES, New York (2023 October)
ABSTRACT
The concentric coplanar stabilizer (C2STM) loudspeaker design theory based on Mikail Dinaburg’s patent is analyzed using COMSOL Multiphysics® modeling as well as comparison to prototypes based on optimized design based on the simulations. A brief description of the design theory is first presented. The building of the simulation model is then illustrated and described, including best practices. The results are presented and the optimization of the design are shown, including a direct comparison of those for a full audio band solution to a similar passive radiator design. The unique acoustic phase behavior in the interior of the design based on the Dinaburg design theory is then illustrated, with the direct relationship of this design’s simulated performance to the measured sound quality and listening tests shown and described. The results indicate performance improvements when compared to a typical passive radiator design. Finally, possible applications of the design theory are briefly listed.
