SB Acoustics SB29RDNC-C000-4 Tweeter

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
