The  Wharfedale  design  principle 
has,  since  our  foundation  in  1932, 
been  one  of  simple  execution  and 
vertical  component  synergy.  This 
principle  is  manifest  within  Opus

2

Every  component,  sub-assembly, 
even  the  crossover  elements  are 
manufactured  entirely  in-house  to 
a  standard  commensurate  with 
the  product  and  with  regard  to 
every  other  component  within  the 
loudspeaker.
Through  this  vertical  integration  we 
are  able  to  ensure  the  cabinets  fit 
the  drive  units,  that  the  operating 
spectrum  of  the  drive  units  work 
with each other and that the whole 
is much greater than the sum of the 
parts - perfect synergy.
This all-embracing approach to design 
pays  dividends  in  performance. 
Because  the  crossover  can  be 

relatively  simple,  phase  linearity 
is  preserved,  meaning  the  drive 
units  move  in  unison  -  a  seamless 
transition  from  one  to  the  other 
without disconnect or interference. 
Because each drive unit is operating 
so  comfortably  within  its  own 
specification,  the  presentation  is 
relaxed  and  confident;  powerful 
and fulfilling.

  loudspeakers  have  a  further 

feature  -  usually  found  only  in  the 
highest quality professional recording 
studios  -  a  dome  mid-range  driver 
capable  of  reproducing  the  entire 
range of human vocal reproduction 
-  with  a  dispersion  characteristic 
which mimics the voice.
Through  this  synergy,  Opus

achieves  one  of  the  most  natural 
presentations  possible  from  a 
moving-coil loudspeaker.
