Loudspeaker design is a challenging task, where the design objective is to achieve better sound quality without violating manufacturing and operational constraints. The quality of sound depends on many parameters; one of them is the ability to control, damp, and shift the diaphragm resonance; another is to control the diaphragm breakup.

In this example the frequency response of a dome tweeter with different diaphragm materials is compared. The frequency response of the composite materials is smoother compared to conventional diaphragm materials like titanium. The ability of composites to break the symmetries in mode shapes and shift resonance can improve the frequency response of a dome tweeter.
