Quad ESL 2912 Electrostatic Panel Speakers
The ESL-2912 is the second model in the ESL range. It employs six electrostatic panels, the inner two utilising the concentric rings of anodes used to create the point source image.
Whilst all electrodes receive the same music signal, each electrode area reacts slightly differently, such that treble frequencies appear to come from the centre of the speaker. Construction is a combination of tensioned aluminum extrusions coupled to stainless steel support structures, with a piano gloss wooden trim.
The substantial base construction is finished with piano gloss side cheeks and high-quality terminations. Internally, the highest quality components are used, including rare core transformers and high-grade audiophile capacitors.
Three types of protection system are used to ensure the speakers are difficult to damage when over driven.
Technology:
- Overload safety
- Electrostatic Panels
- Very low distortion elements
- Crossover free sound reproduction
