SATORI TW29BNWG-8 / Beryllium


  • Beryllium dome for non-resonant high frequency extension
  • Dual balanced compression chambers for improved dynamics
  • Dual copper caps for absolute minimum voice coil inductance and
    minimum phase shift
  • High saturation neodymium motor system with T-shaped pole piece
    for lower distortion
  • Non-reflective cast aluminium chamber with optimized damping for
    improved dynamics
  • Shallow flow optimized magnet structure for optimum coupling to
    rear chamber
  • CCAW voice coil for low moving mass
  • Long life silver lead wires
  • Low resonance frequency for extended range
  • Solid aluminium waveguide
  • Controlled directivity
  • Adapter ring for bolt-less mounting to driver
