Talk:Electrostatic loudspeaker

I am just a casual visitor and playing a completely observational role. However, I feel that no history of electrostatic speakers is complete without a tip of the hat to Harold Beverage and his System 2 and 2SW. His work is being continued by his son Rick, out in California under the name Beveridge Audio. Please check it out. This page should be under the title Electrostatic Loudspeaker as 'speaker' is an abbreviation.

Better still lose the spurious capitalisation, i.e. use Electrostatic loudspeaker --Spliced 23:09, 17 August 2005 (UTC)

Needs Work

As an engineer this reads a bit too much on the audiophile end of things. Terms like "musical transparency" and other nonsense terms drastically lower the quality of the article here on Wikipedia in my opinion. I came here to learn about advantages and disadvantages of electrostatic audio drivers, but the information is too weighed down to be useful. Unfortunately my lack of knowledge in the area, hence why I am researching, also prevents me from fixing it up myself. 98.103.160.18 (talk) 19:54, 5 December 2018 (UTC)

Added electrostatic speaker image.

I have added an image of the schematic of an electrostatic speaker and its connections. Please verify if it is correct and if not then please make or recommend necessary changes. Thank you. Rohitbd 13:40, 29 December 2005 (UTC)

It's correct, nice picture.

Whirling: I'm confused... why is Magnaplanar (Magnepan) not mentioned in the article? Definitely a key innovator in the commercial/consumer market in North America, from the Magnapan III's to today's MG20.1...

Magnepan is not an electrostatic speaker. That's why it's not listed.

To be more precise, Magnepan is a magnetostatic speaker, not an electrostatic one. The principles are similar, but differ in that the magnetostat is current driven and generally a resistive low-impedance load over its range, whereas the electrostat is voltage driven and generally a capacitive load with high impedance in the lower frequencies. And, obviously, one is driven by magnetic fields, where the other is driven by coloumb forces. Zuiram 12:32, 5 October 2006 (UTC)

Magneplanars are not magnetostatic (whatever that is). They are electrodynamic speakers.WilliamSommerwerck (talk) 00:47, 30 April 2009 (UTC)

Deleted "fast impulse response"

There is no such thing as a "fast impulse response". This kind of a term is ambiguous sales man talk whithout any meaning and should not be used. The length in time of the impulse response depends on the bandwidth of the sound radiating device and in particular existance of any energy-storing resonant properties in the device. In essence, most loudspeakers including the electroctatic loudspeaker are minimum phase bandpass systems, and have the associated impulse response. Qwerty182 21:18, 23 October 2006 (UTC)

I thought it had more to do with the fact that the diaphragm is nearly massless and has no metal attached to it, as well as the driving mechanism itself. Even the best dynamic loudspeaker will never be as fast or detailed as an entry-level electrostatic speaker, and the difference in transient response is both noticeable and drastic.PiccoloNamek (talk)

I have included Innersound in the list

I have added Innersound (and their company URL) as one of the current manufacturers of ESL speakers in the US. —The preceding unsigned comment was added by QuadESL63 (talk • contribs) 20:08, 16 April 2007 (UTC).

I have included Dayton Wright in the list

I have included a link and some preliminary information on Dayton Wright speakers. I will add some info on what makes them unique compared to the other designs. —Preceding unsigned comment added by Starheart3d (talk • contribs) 05:27, 24 July 2009 (UTC)

Link corrections

The Accustat link was broken, changed it July 27. 2009 —Preceding unsigned comment added by 68.217.120.69 (talk) 04:36, 25 July 2009 (UTC)

Design and Functionality

"For low distortion operation, the diaphragm must operate with a constant charge on its surface, rather than with a constant voltage(charge and voltage are not the same thing). This is accomplished by either or both of two techniques: the diaphragm's conductive coating is chosen and applied in a manner to give it a very high surface resistivity, and/or a large value resistor is placed in series between the EHT (Extra High Tension or Voltage) power supply and the diaphragm (resistor not shown in the diagram here)."

The conductive coating is chosen for high resistivity? What? The conductive coating is highly resistive. Something doesn't sound right here. Why does the surface need to be conductive if it's suppose to have high resistivity? Some explaination would be good.Longinus876 (talk) 13:59, 11 January 2012 (UTC)

The membrane needs to be conductive enough to eventually get the charge to its whole surface from the wire connected to its edges, but not conductive enough for that charge to get redistributed during one audio signal period. 2001:470:28:8B0:96DE:80FF:FE6F:9AD4 (talk) 18:12, 20 May 2015 (UTC)

Magnepan

Why doesn't article include Magnepan?
