The Tang Band W1‑2396S is a 2.54cm (1") full-range speaker, designed to ensure coherent restitution across entire audible spectrum in space-constrained environments. It leverages mica-loaded polypropylene (PPM) diaphragm combined with vulcanized thermoplastic elastomer (TPV) suspension and neodymium magnet motor, enabling combination of surface rigidity, controlled damping and compact magnetic assembly. This architecture promotes homogeneous response despite minimal diameter, while maintaining controlled behaviour on transients.
Intended for compact integrations, it exploits extremely thin format enabling insertion into spaces where conventional transducers cannot be used. This approach extends to manufacturing consistency from patented design, ensuring performance repeatability from unit to unit, facilitating tuning and reproduction of multi-unit systems while guaranteeing stable restitution over time.
