The specially formulated diaphragm material, unique to the PSD:3003, has a unique combination of stiffness, low mass, dampening, and reduced internal resonances. These factors contribute to an uncolored, vibrant tone (typical of soft-dome highfidelity tweeters) rather than the 'metallic' sound associated with metal diaphragms.
