Composite Sound is as a spin-off from Oxeon, the creators of TeXtreme® Thin-ply Carbon materials. The origin of TeXtreme® traces back to the visionary work of Professor Nandan Khokar, whose innovative concept at Chalmers University of Technology in Gothenburg in the mid-1990s led to the development of carbon materials woven from ultrathin, wide tapes rather than conventional round yarns. This breakthrough enabled the production of composite parts that are significantly thinner, lighter, and stiffer than traditional carbon materials.
The best technology on the planet ...Mars
The first adopter of TeXtreme® thin-ply carbon materials was the Formula One industry, who quickly recognized the potential to create lighter and stiffer composite components — ultimately contributing to faster, more competitive formula one race cars.
The adoption of TeXtreme® technology rapidly expanded into other fields, enabling performance levels and solutions that were previously considered unattainable.
TeXtreme® thin-ply carbon for instance played a crucial role in NASA’s Mars exploration, with the Ingenuity drone’s construction relying on TeXtreme® thin-ply carbon for its unmatched combination of stiffness, lightness, and durability.
The birth of Composite Sound
After 15 years at Oxeon, the engineer Martin Turesson had an idea: could the unique possibilities with TeXtreme® thin-ply carbon benefit loudspeaker diaphragm design?
When talking to transducer engineers and loudspeaker designers, he realized that there was an untapped potential of thin-ply carbon for speaker diaphragms. But to really know, it had to be tested.
To find out, a Thin-Ply Carbon Diaphragm (TPCD®) prototype was produced and tested together with a leading automotive transducer company. The test driver chosen was their top of the line four inch midrange, supplied to a European luxury car brand.
The prototype showed the potential of Thin-ply Carbon Diaphragms (TPCD®), with clarity, detail, and an extended frequency range previously unattainable. What came as a surprise was that this was achieved without the harshness or ringing typically associated with conventional stiff diaphragms.
This validation marked the beginning of Composite Sound TPCD’s journey to becoming the world’s leading diaphragm technology.
