Ask many of the most respected music 
industry professionals in the world what 
their speaker of choice is - the answer 
is surprisingly common. The Quad ESL 
opens a window on a recording unlike 
any other speaker.

More hi-fi critics regard the Quad ESL as 
an absolute reference for their listening 
than  any  other  loudspeaker.  They  are 
regularly praised by leading magazines, 
winning Golden Ears from The Absolute 
Sound  (USA);  and  not  just  ‘Product 
of  the  Year’,  but  also  ‘Component  of 
the  Year’  from  Stereophile  (USA);  a 
Diapason  D’Or  award  (France);  and  a 
‘System  of  the Year’  award  from  Hi-Fi 
News magazine - all of these within the 
last three years alone.

For  those  involved  in  the  recording 
industry, their reputation is unsurpassed. 
The transparency of their reproduction 
has  won  them  many  fans.  For 
professional musicians and studios, this 
is an invaluable asset. It allows them to 
hear exactly what has been recorded in 
perfect balance. 

Because  of  their  speed  and  neutrality, 
they  are  unaffected  by  the  overhang 
and self-imposed character of moving-
coil alternatives.

The  Quad  ESL has  been  used  by Tony 
Faulkner (shown left recording at Henry 
Wood Hall in London) for many years. 
He started using the ESL-63, the ESL-63 
Pro,  and  now  uses  a  pair  of  ESL-989s 
for his critical monitoring.

Tony  has  produced  over  a  thousand 
classical  music  recordings  using  the 
Quad  ESL  because  he  knows  he  can 
trust  what  he  hears  -  that  the  very 
essence  of  the  performance  is  being 
transferred.

Using  the  Quad  ESLs  for  listening 
at  home,  you  can  be  sure  that  your 
experience  will  mirror  that  of  the 
concert  hall.   You  will  hear  detail  and 
depth  never  before  noticed  and  each 
listening session will draw you into the 
music -  transforming your appreciation 
of  every  great  performance  and  every 
great recording.
