The SB21RDCN-C000-4 is a newly designed compact tweeter from SB Acoustics featuring a 21mm ring radiator diaphragm and neodymium magnet system. It has an excellent frequency response to above audibility. 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.

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
Compact low distortion neodymium motor system
Non-resonant rear chamber with optimised damping for improved dynamics
CCAW voice coil for low moving mass
Long life silver lead wires
Low resonant frequency

Basic parameters:

Resonant frequency (fs)	850 Hz	Nominal impedance (Zn)	4 Ω
Effective diaphragm diameter	21mm	DC resistance (Re)	3.1 Ω
Ferrofluid ? Y/N	Yes	Max power handling	40 W
Recommended crossover	2.6kHz/12dB	Faceplate diameter	58mm
Sensitivity (2.83V/1m)	89.5dB	Cutout hole diameter	40mm

The best tweeter I've had and I had

I had many hi end tweeters beryllium, hard soft dome rind radiator any u name it I had it.
Those are the best so soft and detailed.
The rind radiator aka fixed dome center make this tweeter noise free even in very high outputs.
Used it in a 3 way now part of my 4 way.

Thanks for the review Omri !
