StyLight thermoplastic composite chosen by DKM for loudspeaker cone

DKM is a leading international supplier for acoustic parts with over 70 years of experience. DKM’s core business is the development, production and commercialisation of loudspeaker components. The company continuously searches for new materials to optimise the sound of loudspeakers. DKM selected INEOS Styrolution’s composite StyLight as the material for new acoustic membranes for cones, domes and dust-caps in automotive as well as in high-end speakers.

The StyLight Aesthetic S C245 carbon sheet is based on a modified SAN matrix ensuring an aesthetic surface and extremely high mechanical performances. The composite is a material of choice for demanding automotive interior and exterior applications.

Matthias Ringpfeil, technical director at DKM, commented: “When we explored the new StyLight material, it initially convinced with its look. However, when we analysed its acoustic properties, we were even more convinced that we had found the material of choice for our new 6” carbon cone assembly. This has been confirmed by our long term loud speaker customers and we received immediately the first commercial orders.”

Andreas Kolf, business development manager composites at INEOS Styrolution, added: “It is very rewarding to see that our innovative material is selected by an equally innovative company. The collaboration with DKM resulted in a promising new solution and even helped us to learn more about the potential of our StyLight material. We are looking forward to a long term cooperation with DKM to further develop StyLight for innovative high performance acoustic membranes.”
