SB Acoustics SB21RDC-C000-4 Tweeter

UK STOCK ITEM

The SB21RDC-C000-4 by SB Acoustics is a 21mm ring radiator tweeter. The centre of the 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 to above 20kHz.

Key Features:

• Inverted centre phase plug free design
  
• Non-resonant diaphragm design for minimum high frequency break-up
• Dual balanced compression chamber for improved dynamics
• Copper capped pole for reduced voice coil inductance and minimum phase shift
• Saturation controlled motor system for low distortion
• Non-reflective rear chamber with optimised damping for improved dynamics
• Flow optimised vented pole piece for optimum coupling to rear chamber
• CCAW voice coil for low moving mass
• Long life silver lead wires
• Low resonant frequency
