ESL TWEETER

The continuous demand from "do it your self" developers for electrostatic midrange / high frequency loudspeakers has led us to design an electrostatic element. We call it ESL TWEETER. It is a broadband transducer with a take off frequency of 750 Hz and an average reference efficiency of 88 dB. This makes it ideally suited for the construction of 2 or 2.5-way loudspeaker systems.
