Soltanus Acoustics Euridiche 3DIn the development of Euridiche 3D, we used even more of the possibilities of the innovative 3D printing technology. The purpose was to implement two new ideas from aerodynamic sciences and to reduce the weight of the headphone while keeping the virtues of the first model. The first idea was to make aerodynamically ideal, airplane wing like forms for the stator electrode matrix elements, instead of round cross sections, to create ideal turbulence free
