Why create electrostatic speakers when conventional speakers are so much easier to design and build? Clearly, this is a question that could only be asked by someone who has never been held spellbound listening to an electrostat.
Electrostatic speakers are uniquely capable of an extraordinary and compellingly realistic performance with unmatched clarity and three-dimensional sonic imaging (often referred to as 'sound staging' by audiophiles). MartinLogan electrostatic panels have two basic elements: a thin, conductively coated diaphragm with a large surface area and two charged, perforated metal stators. The diaphragm is suspended between the stators. An amplifier's signal, when applied to the stators, creates a strong electrostatic field that moves the diaphragm back and forth, exciting the air and transmitting sound. While in theory all of this might sound relatively simple, in truth, there is an art and science to making this work practically, effortlessly, and reliably. This has been MartinLogan's great contribution—our quest for audio perfection.
