ELECTROSTATIC ADVANTAGES
How can sound be reproduced by something that you are able to see through? Electrostatic energy makes this possible.
Where the world of traditional loudspeaker technology deals with cones, domes, diaphragms and ribbons that are moved with magnetism, the world of electrostatic loudspeakers deals with charged electrons attracting and repelling each other.
To fully understand the electrostatic concept, some back- ground information will be helpful. Remember when you learned in a science or physics class that like charges repel each other and opposite charges attract each other? Well, this principle is the foundation of the electrostatic concept.
An electrostatic transducer consists of three pieces: the stators, the diaphragm and the spacers (See Figure 11). The diaphragm is what actually moves to excite the air and create music. The stator’s job is to remain stationary, hence the word stator, and to provide a reference point for the moving diaphragm. The spacers provide the diaphragm with a fixed distance in which to move between the stators.
As your amplifier sends music signals to an electrostatic speaker, these signals are changed into two
