SB Acoustics SB29BAC-C000-4 Beryllium Tweeter

SB Acoustics logo

The SB29BAC-C000-4 is a 29mm dome tweeter from SB Acoustics featuring an ultra hard beryllium dome mounted inside a cast aluminium faceplate with protective grille. This tweeter sounds very transparent with great dynamics making it a perfect choice for high end systems.

Key Features:

  • Beryllium dome for non-resonant high frequency extension
  • Large surround for increased acoustic output
  • Copper cap for reduced voice coil inductance and minimum phase shift
  • Saturation controlled motor system for low distortion
  • Dual balanced compression chambers for improved dynamics
  • Flow optimised vented pole piece for optimum coupling to rear chamber
  • Non-reflective rear chamber with optimised damping for improved dynamics
  • Long life flexible lead wires
  • Cast aluminium faceplate
  • Low resonant frequency

Basic parameters:

Resonant frequency (fs) 650 Hz Nominal impedance (Zn) 4 Ω
Effective diaphragm diameter 29mm DC resistance (Re) 3.0 Ω
