Why Electrostats Are Better

This amazing breakthrough speaker technology is still the best available today because it has 50-100 times lower distortion than conventional electromagnetic (dynamic) speakers. 

Lower distortion increases musical transparency, leading to the highest fidelity from reproduced music at home, with increased clarity, resolution, articulation, and imaging precision.  Simply put, electrostats are more faithful to the original studio master recording or the live musical event than any other speaker technology in audio history.  Nobody argues about that anymore, its proven fact. 

Only a small handful of electrostatic speaker manufacturers exist today, producing them is much more challenging than putting a woofer, tweeter, & crossover into a box and calling it a speaker.  Essence Electrostatic speakers are unlike all the other electrostats on the market, designed to overcome the practical limitations the technology can impose.  Learn more about the Essence here….. 


Comparison between dynamics and electrostats:


1) Stats use electrostatic force to vibrate a nearly weightless (low mass) membrane. Dynamics use electromagnetic force to vibrate a cone.

2) The force on a stat’s membrane is spread out evenly, so the membrane moves as one. Cones are pushed from the middle and vibrate in ways other than the ideal in-out motion.

3) The force on a stat’s membrane is simply proportional to the voltage at all times, so linearity and low distortion occur naturally. The position of a cone, however, is a complex function of current plus half a dozen continually changing parameters, making linearity and low distortion impossible under typical operating conditions.

4) A stat’s membrane is as thin as a twentieth of a sheet of paper, far lighter than the air it is vibrating against, so very little power is used to vibrate it. A cone and its driver coil are at least 100 times as heavy and sprung by a spider and surround, so most of the power goes to move all that.

Musical transparency can be better than in electrodynamic speakers because the radiating surface has much less mass than most other drivers and is therefore far less capable of storing energy to be released later. For example, typical dynamic speaker drivers can have moving masses of tens or hundreds of grams whereas an electrostatic membrane only weighs a few milligrams, several times less than the very lightest of electrodynamic tweeters.*
