# Redefining Diaphragm Technology

Composite Sound's mission is to redefine diaphragm technology to enable you to set new benchmarks. We achieve this by engineering Thin-ply Carbon Diaphragms (TPCD®) for solutions and performance levels beyond what is possible with conventional diaphragms. 

 

### Our Markets

### [![Composite\_Sound\_Speaker](https://composite-sound.com/hubfs/Optimerad_Speaker.jpg) Hifi We engineer TPCD® diaphragms for pistonic motion and controlled resonances. You will hear the difference regardless if it is a tweeter, a midrange, a woofer or a fullrange.](https://composite-sound.com/tpcd-technology-hifi-pro-audio-headphone-automotive#lnk-hifi)

### [![Headphone](https://composite-sound.com/hubfs/Headphone.webp) Headphone Controlled resonances and pistonic motion over the entire frequency range results in superior sound quality.](https://composite-sound.com/tpcd-technology-hifi-pro-audio-headphone-automotive#lnk-headphone)

### [![Line-array](https://composite-sound.com/hubfs/Line-array.jpg) Pro-Audio We engineer TPCD® compression driver diaphragms to enable you to play louder, with better sound quality and with outstanding durability.](https://composite-sound.com/tpcd-technology-hifi-pro-audio-headphone-automotive#lnk-pro-audio)

### [![Car](https://composite-sound.com/hubfs/Technology_Optimerad/Car.webp) Automotive Use the leading diaphragm technology from hifi and communicate the TeXtreme® heritage from Formula one and NASA's space explorations.](https://composite-sound.com/tpcd-technology-hifi-pro-audio-headphone-automotive#lnk-automotive)

## Born from Space and Formula One

Composite Sound is a spin-off from Oxeon, the inventors of TeXtreme® Thin-ply Carbon.

 TeXtreme® is used where only the absolute highest performance materials are good enough, such as Formula One and Aerospace. NASA's drone Ingenuity flying on planet Mars is for example built from TeXtreme® Thin-ply Carbon. 

Composite Sound combines space material technology with advanced engineering to create the world's best speaker and headphone diaphragms.
