The book you hold, one of the most hard-to-find volumes in the loudspeaker field, is a slightly abbreviated version of that first published by TAB Books in 1987. Well known as both a "how-to" book and an informative text on electrostatic speakers, it will provide you with step-by-step sequences for building full-range electrostatics as well as acquaint you with their basic operating principles. Author Wagner also explains here the important parameters of an electrostatic speaker and indicates how each affects its performance.

Intended for the audio amateur, musician, or craftsman, this book is also a classic acquisition for anyone who is interested in this type of speaker and searching for the very best in sound reproduction. In addition, it provides a rich source of information for everyone involved in electrostatic loudspeaker research, repair, or restoration.

The most obvious reason for writing a book on ESL is that it hasn`t been done before . Beyond that, there are a number of other factors that are more important. First, there is the fact that existing books on speakers and acoustics only present some of the theory of how ESL operate. Very few , if any, ever indicate how to build one. Second, in addition to the construction details, this book can be used as a reference source for the theory and history of ESLs and transducers. For the reader who is interested in pursuing the subject in more detail, the text contains patent numbers.
