Type of speaker that uses positive and negative electric charges over two thin panels, one stationary and one moveable, to generate sound (two positive or two negative charges repel each other while a positive and negative attract each other enabling movement and thus sound production). lectrostatic speakers are very thin compared to conventional speakers. They have a single large, rectangular area that contains the two charged panels (most designs actually use three panels with the moveable panel sandwiched between two non-moving panels). The moving panel is a very thin, often see-through diaphragm. It is suspended in close proximity to one or two stationary panels that create a high-voltage field. The field created by the stationary panels remains constant. The electric field running through the moveable panel, on the other hand, changes in polarity (positive or negative charge) based on the audio signal coming from the amplifier. As the panel becomes more negative, it is attracted to a positive stationary panel. As it becomes more positive, it is repelled. This attraction and repulsion creates movement in the panel. he primary advantage of electrostatic speakers is that the moveable panel is of very low mass meaning that it can move and react to sudden sonic changes quicker than a traditional speaker using traditional dynamic speaker drivers (cones and domes). The cones and domes of traditional drivers are comparatively high in mass and thus require a large amount of power to control them. Electrostatic speakers’ low mass characteristics lend them to excellent transient response and definition of subtle detail. n the negative side, electrostatic speakers must be plugged in at a wall socket to maintain a charge across their panels. Additionally, they are not as adept at low frequency reproduction than traditional dynamic speakers. To combat this problem, many electrostatic speakers include a cone woofer or are mated to a subwoofer. Electrostatics also do not always produce as much high-volume, high-impact sound as traditional dynamic speakers making them less well suited to home theater tasks. lectrostatic speakers are exotic in their looks and can produce great results within their limitations, but they are less flexible and much less widely used than their conventional dynamic counterparts.
