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.
