CIMERA® multilayer composite materials can be used for flat or formed loudspeaker diaphragms such as plates, cones or domes. CIMERA® allows very high stiffness even for flat and slightly formed structures.


Most important requirements for loudspeaker diaphragms:

  • High break-up frequency / wide “pistonic” range
  • High damping / no peaks in SPL response
  • Low weight for high sensitivity or magnet cost saving
  • High temperature resistance

Solid materials show high stiffness OR high damping - CIMERA® sandwich materials combine both!
