Traditional speaker cone with an aluminum cone
Composite Sound Metamodal A
Composite Sound Metamodal B
Composite Sound Metamodal C
Tailored frequency response
The ability to engineer the modal behavior, in other words to tailor how different parts of the cone or diaphragm behave at different frequencies, enables the ability to tailor linearity, distortion, directivity etc. This is exemplified with this set of frequency curves showing different Composite Sound Metamodal cones of the same geometry in the same driver, engineered with different modal behaviors with resulting different frequency curves.
