SB Acoustics Satori Logo


The Satori TW29RN-B-8 (black trim) by SB Acoustics is a 8 ohm ring radiator tweeter featuring a textile diaphragm and a low distortion flow optimised neodymium magnet assembly. This is an upgraded version of the renowned TW29R.

There are 4 variants:

TW29RN: Silver trim, 4 ohm .

TW29RN-8: Silver trim, 8 ohm.

TW29RN-B: Black trim, 4 ohm.

TW29RN-B-8: Black trim, 8 ohm (this page).

Key Features:

  • Inverted centre phase plug free design
  • Non-resonant diaphragm design for minimum high frequency break-up
  • Two part aluminium faceplate with integrated mechanical decoupling
  • Dual balanced compression chambers for improved dynamics
  • 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
