Murata ES103 Spherical Super Tweeter

[Σπύρος Μπλάτσιος]

κεραμικό Super tweeter με πιεζοηλεκτρική σχεδίαση!!!

'Unlike conventional speakers, our ES103 tweeters produce sound through piezoelectricity: the semispherical ceramic membrane itself acts as the tweeter medium. With traditional speakers, the characteristic resonance frequency of the vibrator medium is set below the reproduction bandwidth; but with the ES103, the ceramic medium has resonant frequency that lies above this bandwidth. This means that the diaphragm provides extremely faithful tracking of the input signal, resulting in superlative transient characteristics and delicate, rich sound reproduction. These tweeters enhance playback from a wide variety of audio media, from CDs and LPs to SACDs and DVD audio.'
