This tweeter member of the classical product family. This driver features a 4ohm 25mm voice coil, a damped silk diaphargm with large surround roll to produce a low resonant frequencey, with a neodymium magnet mtor and plastic faceplate . The driver operates the effective frequencey response between 800Hz to 40KHz. It designed to be a high performance transduer.
