The latest version of the highly acclaimed ESL series, the ESL-2912 are a celebration of a classic. Using the signature mylar diaphragm, yet while re-evaluating all circuitry and components, the result is an authentic ESL experience - incredible full range accuracy and startling realism.

 

Why is the Quad ESL more accurate than any other loudspeaker?
Why the Quad ESL is able to do so is simply because of the moving part of the Quad ESL, the electrostatic diaphragm, which is a thin layer of stretched Mylar, ten times thinner than a human hair and so light that it approaches the mass of air to which it is coupled.

As a result there is no inertia inherent in the moving parts of the Quad ESL and the diaphragm is able to respond to musical detail and transients with unparalleled precision. The Quad ESL is one of the few speakers that can reproduce a 1kHz squarewave precisely and cleanly.

To achieve this astonishing feat the Quad ESL uses a system of highly charged stator elements on either side of the diaphragm which is coupled to a power supply that produces the neccessary 5kV of EHT (Extra High Tension) charge that controls the diaphragm.

 

Attention To Details
Attention is paid on the power supply section, especially the stators. Each stator consists of a layer of copper on a thin, insulating backing, which is punched with a pattern of holes to make it transparent to sound. The copper is etched to provide a conductive pattern which is necessary to re-create the point source attributes of the Quad ESL. After etching, the copper needs to be insulated from the diaphragm, which will lie in close proximity to it.

In the 2812 and 2912, the insulation is created by a triple coating utilizing a specific spraying technique that is perfected to avoid degradation of the EHT charge nder high dynamic conditions, where the diaphragm comes into close contact with the stator. These latest versions of the Quad ESL can thus play louder and handle more power than the previous models.
