TAC Diamond Diaphragm Technology

The Application of ta-C Coating Technology in Speaker Diaphragm for Transient Improvement. In the ever-evolving world of audio technology, the quest for superior sound quality has led to innovative advancements in speaker design. One such breakthrough is the application of tetrahedral amorphous carbon (ta-C) coating technology in speaker diaphragms.

Why TAC Coating?

ta-C coating enhances the mechanical properties of speaker diaphragms by increasing stiffness while maintaining low mass. This results in faster transient response, reduced harmonic distortion, and improved clarity across the frequency spectrum.

Our proprietary coating process ensures uniform thickness and adhesion, making it ideal for high-end audio applications where precision and reliability are non-negotiable.

  • • Superior stiffness-to-mass ratio
  • • Extended frequency response
  • • Lower resonance peaks
  • • Long-term durability
  • • Compatible with various substrate materials
