THE LEADER IN ELECTROSTATIC TECHNOLOGY

THE Electrostatic speaker in its basic form consists of two performated metallic screens which are insulated and sandwich a high resistivity coated plastic diaphragm. The diaphragm must be highly resistive to enable it to conduct and retain a high voltage charge of 2000-6000 volts.

An audio step up transformer is electronically connected to the front and rear screens. When an audio signal is applied to the transformer input, it modulates this signal between the two screens, varying the elctrical field between the screens and the highly charged diaphragm which then vibrates the surrounding air to create the 'sound'.

THE ULTIMATE LOUDSPEAKER TECHNOLOGY: If we study every technique which has been used to vibrate some form of diaphragm to produce music, the electrostatic has four very important features.

• 1. It has diaphragm which is virtually weightless, bipolar and extremely linear in its opoeration to yield the lowest distortion of any loudspeaker technology. This also enables it to reproduce the widest frequency response of any single driver system.
• 2. The means of energising the system does not rely on using many heavy magnets with intense magnetic fields, but by simply controlling the mylar diaphragm-to-screen spacing and varying the external high voltage supplied to the diaphragm.
• 3. The diaphragm is devoid of the cabinet colourations of conventional 'box' speakers, with a transient response which defies even the fastest ribbons without their metallic colouration.
• 4. Normal loudspeakers absorb a considerable amount of power to simply overcome the mass of their cones and energise their complicated crossover networks before they start reproducing music.

This restricts the low-level performance of a system which then compresses the real dynamic range of a musical performance. In particular, fine music detailing and room acoustic information is lost.

The inherent linearity of MAS electrostatics allows listening at whisper sound levels. The natural dynamics of music are not compressed and so musical recordings are more spectacular at far lower listening levels than one is used to with other speaker technologies. Your low level hearing improves as you do not need to stress your ears in the pursuit of listening pleasure.
