Electrostatic & Ribbon

Electrostatic & Ribbon speakers are very different from traditional dynamic speakers. In an electrostatic speaker, a thin, large conductive diaphragm is stretched between two stationary conductive panels. These panels crate a positive and a negative end. When the panels are charged with electrical current, the panels vibrate from negative to positive and from positive to negative.

To explain the process in brief- in an electrostatic stereo speaker, an amplified sound signal is first impressed onto the panels, thereby polarizing the metal sheet. This results in an electrostatic force, which creates a motion of the panels and thus sound wave is produced.

Ribbon speaker on the other hand has a ribbon metal suspended between two magnetic panels. The magnetic field moves the alternating positive and negative current. Audio enthusiasts mostly use both of these speakers. For the regular customers the traditional dynamic speakers are still the best.

Okay, now let us learn a little bit more about Acoustech electrostatic speaker. An electrostatic speaker requires a very high voltage to drive it. Electrostatic speaker bias transformer is designed to step up the voltage. Besides providing the step up voltage, electrostatic speaker transformer also matches the impedance of the speakers to the power amplifier. So without the inverter your electrostatic speaker simply would not work.

If you are looking for inverter bias supply electrostatic speaker in the US, you can count on Martin-Logan and Sound Lab. Over the years electrostatic speaker technology has greatly improved to take care of some of the drawbacks associated with ESL. For example, Martin-Logan’ Summit electrostatic speakers combines dual independently powered woofers with its most advanced electrostatic transducer- XStat.

When people think about ESL, they usually have the misconception that ESL requires large amounts of power to operate. This is false today. Martin Logan’s speakers can use any amplifier or receiver commonly used. Another misconception that surrounds ESL is that they can be dangerous due to the high voltage that is required to move the plastic film. Today’s Martin Logan’s models use high quality insulators and the plastic film never touches the stators.

So get rid of the misconceptions, try an electrostatic system, and see the difference in sound. They are very lightweight and give very clear and precise sound. They are highly suited for today’s multi-media systems. if you are thinking that you will have trouble finding electrostatic speaker parts, you need not worry. Spare parts are easily available from authorized dealers of Martin and Logan and Sound Lab. Once you have hooked an electrostatic speaker to your home theater system, you will never go for any other speaker type.
