The diaphragm utilizes an ultra-thin 1μm planar diaphragm. This exceptionally thin 1μm diaphragm delivers lightning-fast response speed, faithfully reproducing delicate high-frequency signals while providing outstanding dynamic range and frequency characteristics.

 

The voice coil incorporates two precious metals - gold and pure silver - processed through multi-layer plating, giving the FT7's sound both rich musicality and detailed resolution. Gold offers exceptional malleability and high density, effectively improving diaphragm damping for warm and nuanced mid-low frequencies. Pure silver boasts high conductivity, enabling rapid high-frequency current transmission with minimal loss for refined treble and high resolution.
