SB21RDCN-C000-4
UK STOCK ITEM
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.

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 !
