Core technology: diamond carbon fiber composite diaphragm

Loudspeaker   (17)

Using " nano-penetration coating cutting-edge technology " , diamond molecules are allowed to penetrate into every gap of carbon fiber like " liquid " , and through high-energy particle bombardment, the molecules are bonded, and the multi-layer carbon fiber substrate and diamond coating are melted into a " seamless monomer structure " ! So it's not plating, it's rebirth.

● " Three-dimensional steel skeleton " :
Internal carbon fiber mesh skeleton + surface 2μm diamond armor, rigidity increased by 400% .

● " Hardness and Softness " :
Mohs hardness 10 + damping coefficient 0.25 , residual vibration attenuation speed reaches 0.8ms (traditional diaphragm 5ms ), Completely eliminate the " metallic taste " ;

● " Acoustic Zero Loss " :
One-piece molding eliminates 99% of interface reflections, and the high-frequency purity is comparable to that of an electrostatic unit!

Each diaphragm undergoes 36 hours of supercritical process + 3D-CT inspection.
