[New-generation T-shaped carbon nanotube composite diaphragm] The new-generation carbon nanotube composite diaphragm is lighter than previous-generation diaphragms and offers significantly improved physical properties. Carbon nanotubes have excellent mechanical and acoustic properties, with strength 400 times that of steel, the only material with mechanical properties currently known to mankind. They can be used to compound PU materials, improving the diaphragm's transient frequency, resulting in clearer sound and a clearer image. [Excellent Support Design] The excellent support design allows the diaphragm diameter to be increased, increasing the effective vibration area by 8% compared to conventional flange structures. [Super Magnetic Circuit Design] Thanks to the super magnetic circuit design, the T Iron is made of high-magnetic-conductivity alloy material and precision CNC machining. Compared with traditional hollow-core T Irons, its magnetic conductivity is increased by up to 50%. The unit frame has excellent breathability and strength. When the diaphragm vibrates, it can minimize reflections generated by the frame. [New-generation carbon nanotube composite diaphragm technology] The new-generation carbon nanotube composite diaphragm is lighter and has significantly improved physical properties compared to previous-generation diaphragms. Carbon nanotubes have excellent mechanical and acoustic properties, and are 400 times stronger than steel, making them the most mechanically superior material known to mankind. [High-Density External Magnetic Structure Design Magnetic Circuit for Stronger Energy Output] The N54 super external magnetic circuit design ensures purer and thicker low-frequency sounds. The T-iron is made of highly magnetic and conductive alloy material and precision CNC machined. Compared to traditional punched hollow T-irons, its magnetic conductivity is increased by 50%. The breathable brass support effectively reduces sound wave reflections when the diaphragm vibrates.
