Murata Manufacturing's ceramic super tweeter improved based on the ES103. The natural resonance frequency is set higher than the playback band using spherical piezoelectric ceramics, and high followability of the diaphragm to the input signal is realized. It has excellent transient characteristics, and it is possible to reproduce sounds that are delicate and full of realism. It is compatible with a wide range of speakers, and the afterglow and expansion of spatial expression are remarkable. There is dullness and feeling of use (Kanai Hidetsugu)
