SB Acoustics logo

The SB29BNC-C000-4 by SB Acoustics is a 29mm beryllium dome tweeter featuring a compact body and neodymium magnet system. This top quality small form factor tweeter offers great versatility and is ideal for high end in-car systems.

Key Features:

  • Beryllium dome for non-resonant high frequency extension
  • Copper capped pole piece for reduced voice coil inductance and minimum phase shift
  • Internal pressure equalisation and flow resistor for non-resonant coupling of cavities
  • Saturation controlled motor system for low distortion
  • Shielded neodymium magnet system
  • Long life flexible lead wires
  • Low resonant frequency
  • Compact design
