R&D Stories: TPCD Technology in Headphones - Engineering to Control Diaphragm Resonances

This article details how thin-ply carbon diaphragm (TPCD) technology can also be applied to headphones, allowing precise control of diaphragm resonances rather than trying to reduce its negative effects, as the speaker industry already recognizes. As the pioneer of TPCD technology, Composite Sound is now entering the over-ear headphone market with its Metamodal TPCD engineering approach, enabling headphones with better sound quality, improved bass performance, and higher sensitivity.
