TB900X tweeter match up to B&C DE900 HF driver
Unique advantages
◆ 12 exclusive processes: from ultra-fine carbon fiber weaving to diamond molecule deposition, zero-tolerance quality control throughout the entire process!
◆ Data crushing: diaphragm hardness/damping/rigidity in three dimensions surpass traditional metal units !
◆ Acoustic supremacy: The world's first tweeter driver to achieve "zero-division vibration"!
◆ Applicable fields: million-level Hi-End speakers/ten thousand-person stadium accoustic system/aerospace-level monitoring system !
Core technology: diamond carbon fiber composite diaphragm
◆ 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.
