What Is Electrostatic Flat Panel Speaker (ESL)?

- Aug 29, 2018-

The electrostatic flat panel speaker uses two metal grids with a diaphragm made of a plastic sheet. The sheet is coated with graphite which is electrically conductive. The diaphragm has a constant charge; high voltage audio signal is created by the grids which are really electrodes.

It has poor bass response but the speakers look interesting as a rectangular flat screen. If combined with a regular electrodynamic woofer it can be made into a full sound system.
