Spec Sheet PDF

Small profile ring radiator. This is a very high efficiency for a small format tweeter. Consider this tweeter for autosound or small bookshelf speaker applications.  

The SB21RDCN-C000-4 is a newly designed compact tweeter from SB Acoustics featuring a ring radiator diaphragm and neodymium magnet system. It has an excellent frequency response well above 20 kHz. The center 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.

• Non-resonant diaphragm design for minimum high frequency break-up
• Copper cap for reduced voice coil inductance and minimum phase shift
• Compact low distortion neodymium motor system
• Non-resonant rear chamber with optimized damping for improved dynamics
• CCAW voice coil for low moving mass
• Long life silver lead wires
• Low resonance frequency
• Small 58mm flange (2.28")

Ring radiator tweeters offer superior break-up modes compared to similar dome diaphragm models. This means the upper frequency range tends to be cleaner (lower distortion) and offers more extended response than similar conventional dome tweeters.
