SB Acoustics Satori TW29BNWG-4 Beryllium Tweeter

SB Acoustics Satori Logo


The Satori TW29BNWG-4 from SB Acoustics features a horn loaded front waveguide, a beryllium dome and a neodymium magnet assembly giving a broad frequency range with controlled directivity. Very high output of 97dB, 4 ohms impedance.

Also available in 8 ohms: TW29BNWG-8.

Key Features:

  • Beryllium dome for non-resonant high frequency extension
  • Solid aluminium front horn / waveguide
  • 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 optimised damping for improved dynamics
  • Shallow flow optimised magnet structure for optimum coupling to rear chamber
  • CCAW voice coil for low moving mass
  • Long life silver lead wires
  • Low resonant frequency for extended range
  • Adapter ring for bolt-less mounting to driver

Basic parameters:

Resonant frequency (fs) 700 Hz Nominal impedance (Zn) 4 Ω
