1.4" | AMT2838
Air Motion Transformer
Key features:
  • Smooth frequency response in working rage, very low harmonic distortion

  • compact design with integrated waveguide

  • Best use in high performing hi-fi audio systems

Design notes:
    • Introducing our Air Motion Transformer AMT2838, meticulously engineered to elevate the auditory experience in high-fidelity audio products. Designed to be the pinnacle of sound reproduction, the AMT2838 delivers ultra-clean, detailed, and well-defined mid to high-frequency sound, setting a new standard in audio excellence.Crafted with precision manufacturing,
    • stringent quality control processes,and advanced glue dispensing techniques, our AMT2838 is engineered for long-term durability and unwavering performance, ensuring that the product in your hands is synonymous with reliability and stability.The AMT2838’s magnetic system provides a robust B field to the formed diaphragm, enhancing its overall performance
    • and contributing to its exceptional sound output. The diaphragm assembly is a marvel in engineering, featuring polyimide foils encapsulating aluminum conductive film. Our innovative high-precision forming technique ensures that each diaphragm is crafted with a high degree of repeatability, enhancing unit-to-unit consistency and delivering stability, resulting in unparalleled audio performance.
