electrostatic loudspeaker

The electrostat, like the magnetostat, is an area radiator and fullrange loudspeaker. The frequency ranges ofelectrostats cover the entire audible frequency range, from about 20 Hz to well above 20 kHz. In terms of construction, the electrostatic loudspeaker consists of the grid electrodes, also called strators, the membrane foil and the frame with the spacers. The membrane foil has an extremely low mass and is biased with a polarizationvoltage of 1,000 to 5,000 volts. The bias voltage prevents the diaphragm foil from oscillating through the quiescent state, which would cause frequency distortion. Structure of an electrostat The audiosignal from the audio amplifier is applied in push-pull to the two grid electrodes. As a result, the membrane foil is electrostatically influenced by both electrodes simultaneously: one pushes, the other pulls. The membrane movement converted into sound is radiated through the grid electrodes. Electrostatic from Quad-MusicAmplifier drive and design is more problematic with solid-state electrostats than with other loudspeakers because the electrostate's impedance
