Electrostatic Loudspeaker Design Cookbook (Repost)

The Electrostatic Loudspeaker has intrigued music lovers since their commercial introduction just after World War II. Hearing music via such a device often turns ordinary music listeners into dedicated, passionate partisans of this transducer format as the only true path to accurate sound reproduction. Add to this additional incentive that such speakers can be constructed out of readily available materials, and the convert turns into a devotee ready to invest quantities of time and energy into the nearest equivalent of the perfect loudspeaker. The ability to move a panel of graphite impregnated plastic immersed in a high voltage field with audio signal has fascinated audiophiles since the earliest days of high quality sound reproduction after World War II. This enthusiasm leads inevitably into explorations of the legendary output transformerless amplifier (OTL) genre since such devices match their high impedance outputs ideally to the electrostatic's input. Then there is the electrostatic headphon e sideshow which beckons tantalizingly. No one writing about the electrostatic has contributed more to the success of amateur speaker builders than Roger R. Sanders. His first article on the topic appeared in The Audio Amateur in 1975 (pp. 18-28) His designs were inspired to some extent, and informed by, the pioneering work of David Hermeyer, who published a series of Audio Amateur articles on building electrostatics, along with power amplifiers designed to drive them. Electrostatic builders have strong opinions about ideal formats, stator structure, polarizing voltages and many other details. In this book the author surveys all the alternatives and keeps clear about his own preferences, many of which are subjective. The Electrostatic Speaker Design Cookbook is a complete guide for the novice and the experienced builder to successfully build the unusual sound reproduction device. From back cover of this book
