Quad ESL
The
Contemporary Electrostatic Loudspeaker Design
The new ESL-2805 and ESL-2905 
Electrostatics are Quad’s latest reference 
loudspeakers and like their predecessors 
should be regarded amongst the finest 
loudspeakers in the world today. In 
areas such as transparency, and lack of 
colouration, they are without peer.
It should be noted that whilst moving-
coil loudspeakers are the norm, the 
physical principles upon which they 
work are fatally flawed - and not even 
the latest advances in materials science 
can address their shortcomings.
Quad alone has sought a different path 
- to push the boundaries of electrostatic 
technology to the point where our ESLs 
are closer to the ideal loudspeaker than 
any other.
Quad’s patented panel technology 
results in a combination of the speed 
and accuracy only possible from an 
electrostatic loudspeaker; together 
with the imaging and soundstaging 
only possible from a theoretically ideal 
point source; and the coherence and 
continuity of a single drive unit.
With possibly the lowest distortion 
of any loudspeaker, the ESL can be 
enjoyed for hours on end without 
fatigue; never adding or subtracting 
from the original recording. Even at low 
volume levels, they retain the full detail 
and drama of the music.
In short, the Quad ESL technology is 
unique in its clarity of sound, lack 
of distortion, lack of interference and 
continuity of response.
The
ESL-2805
and
ESL-2905
loudspeakers are the absolute pinnacle 
of that technology. Engineered without 
compromise, they are destined to 
become modern classics.
