The Audiostatic Philosophy
Be it from a piano string, clarinet reed, drum skin or vocal chord; the beginning, middle and end of any sound is vibration, making high-fidelity sound reproduction a trickly proposition. In the recording process, you are starting with a sound source such as a violin string, which vibrates at a certain primary frequency of cycles per second, yet alos creates a variety of secondary frequencies or harmonics. This vibration pressurizes the nearby air, producing sound waves that cause objects in the vicinity to vibrate in unison. If these objects are sensitive devices such as microphones, containing a single responsive membrane capable of matching all of the primary and secondary vibrations of the source, a coherent translation of acoustic energy into electric energy can be made.
Ideally, the translation in playback from electric to acoustic energy should be exactly the reverse of the recording method. That is, the end of the playback chain should be a single, coherent membrane that acts as a microphone in reverse, capable of matching the vibrations of the original instrument and exciting the eardrums to move in unison.
Conventional, planar and ribbon two-way or three-way cross-over-type speakers do not behave like either the microphone or the original sound source. They attempt to divide the source into two or three separate vibration sources, reuniting them in mid-air. This results in a lack of coherency or faithfulness to the original sound, simply because a vibrating violin string does not break itself into two or three separate frequency elements and then reintegrate these separate frequencies in mid-air at the microphone.
An Audiostatic electrostatic speaker is a device that works essentially as a microphone in reverse. It uses no crossovers to artifically create a frequency division which did not exist in the source, and because its moving mass is so much lighter than conventional, planar and ribbon speakers, it is capable of the very fast acceleration and deceleration necessary to keep up with the complexity of the original sound.
The Audiostatic ES 100 Series
Audiostatic ES 100 series are pure full range electrostatics. The heart of each Audiostatic electrostatic loudspeaker is the multi suspension (US patent 4105877) electrostatic element with ultra low mass membrane.
To prevent even the smallest irriqularities in sound, the frames of the ES 100 series are of a solid, 35 mm thick m.d.f. construction. There is no sound-degrading obstruction like grille cloth between the loudspeaker membrane and the listener's ear. Only computer grade electronic components are used, with polypropylene capacitors in the sound path. Massive 18 crt. Goldplated terminals are standard, accepting every possible loudspeaker cable. Finish is in beautiful spekled lacquer, available in 16 colors without extra charge.
The Audiostatic Modular Design
Bipolar full range electrostatic need careful room matchment to insure optimum reproduction of low frequencies. For this reason the ES 100 can be extended with the SW 100 electrostatic subwoofer, to achieve the best possible results in larger rooms.
The SW 100 simply can be switched in parallel with the ES 100, without dropping the overal impedance below 4 ohms.
