SB Acoustics SB29RDNC-C000-4 Tweeter

SB Acoustics logo

The SB Acoustics SB29RDNC-C000-4 is a very compact 29mm ring radiator tweeter featuring a neodymium magnet system. The centre of the ring diaphragm is inverted and bonded to an internal dimple on the pole piece, this innovation negates the need for a front phase plug and gives excellent extension.

Key Features:

  • Inverted centre phase plug free design
  • Non-resonant diaphragm design for minimum high frequency break-up
  • Copper capped pole for reduced voice coil inductance and minimum phase shift
  • Shielded neodymium magnet system
  • Internal pressure equalization and flow resistor for non-resonant coupling of cavities
  • CCAW voice coil for low moving mass
  • Long life silver lead wires
  • Low resonant frequency
  • Compact design

Basic parameters:

Resonant frequency (fs) 680 Hz Nominal impedance (Zn) 4 Ω
Effective diaphragm diameter 29mm DC resistance (Re) 3.0 Ω
Ferrofluid ? Y/N Yes
Max power handling 100 W
Recommended crossover 2.6kHz/12dB Faceplate diameter 72mm
