QUAD ESL 2805 - Manual (Page 14)

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.
