Acoustic Components Acoustic diaphragms
Diamond Speaker Domes
Thin, curved diamond diaphragms for high-frequency loudspeaker drivers.

Good to know
- Diamond’s stiffness supports lightweight diaphragm designs.
- Dome geometry and wall thickness influence mechanical behaviour.
- The suspension, motor and enclosure determine performance with the diaphragm.
