英国QUAD(国都 ) ESL-2912 旗舰豪华版静电扬声器

ESL2912由于不需要大型密闭式箱体结构，可以轻易的保持无音染声音源源不断的供应。“超大箱体”的使用可以使低音稳定的保持在40HZ以下。

ESL2912中间的两块面板采用了隔板两边定板上同轴圈的导电原理，每个圈会发生极短时间的延迟并被它自身的圈环减弱，声音逐渐的从中间传播到每个连续的环中。

这使得点声源能产生一场近乎完美的球面波，从而成就了音箱在立体声像和凝聚性上无可比拟的精确度。这些特色的相互结合使得ESL2912成为史上失真率最低的音箱之一。

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.
