The  overall  measure  of  success  of 
a  high-end  loudspeaker  system  is 
to  design  a  loudspeaker  that  is 
both accurate and natural, very low 
in  distortion,  which  covers  a  wide 
band-width  of  frequencies  and  can 
provide  immense  pleasure  to  the 
listener over long periods of time.

Many  of  these  criteria  can  be 
designed into a system through careful 
measurement and analysis, but the final 
factor - the ability to provide pleasure 
to  the  listener  is  a  black  art  –  a  skill 
developed  by  the  master  acoustician 
over a lifetime of experience.

Opus

 loudspeakers meet all the pre-

requisites  of  performance  –  in  fact 
in  measured  tests,  they  outperform 
all  their  peers  and  many  which 
cost  considerably  more.  The  final 

arbiter  though,  the  human  ear,  is 
the  most  important  test  of  all  -  and 
all Opus2 loudspeaker models have 
undergone a two-year long process 
of  listening  and  tweaking  before 
final  approval  to  refine  and  further 
refine  their  balance  to  the  point 
where  the  loudspeaker  acoustically 
‘vanishes’ – leaving just the music.

Only  when  a  loudspeaker  truly 
represents  not  only  the  tonal 
integrity  and  clarity  of  the  original 
performance,  but  also  is  so  finely 
balanced  that  it  communicates  the 
genuine  passion  and  raw  emotion 
of the live performance, can we be 
satisfied that all the design objectives 
have been fulfilled.

All Opus2 loudspeakers meet these 
most stringent objectives.
