The ESL-2905 is the larger of the two models - it employs a grand total of six electrostatic panels; the inner two utilising the concentric rings of anodes used to create the point source image.
The ESL-2905 has a fifty-percent greater diaphragm area than its smaller brother. This increase allows for a markedly improved bass response, and greatly enhanced dynamics. The ESL-2905 is therefore a good choice for those in larger rooms, or those seeking more drama on big pieces. However, this speaker doesn’t compromise on detail and subtlety - far from it. After all, it is an electrostatic design and so has considerably less inertia and overhang than any moving-coil loudspeaker.
Construction is a combination of tensioned aluminium 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 c-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.
A rigid three-dimensional structural support system, combined with an overall speaker mass of 41.6kg ensures the maximum transmission of sound energy. This results in the most dynamic and powerful Quad ESL ever produced.
