It  is  often  said  that  a  loudspeaker 
is  the  weakest  point  in  any  audio 
system  and  this  is  largely  true.  It 
is  the  point  at  which  the  electrical 
signal is converted into compressions 
and  rarefactions  within  the  air  that 
our ears recognise as sound.

The  mechanics  of  this  transfer  of 
energy  and  how  accurately  this 
occurs  is  a  constant  battle  for  the 
loudspeaker engineer and one which 
we,  at  Wharfedale,  have  lead  the 
field for over seventy-five years.

The  measured  performance  of  our 
Opus

2

  system  is  a  testament  to  this 

success.  We  have  engineered  a 
loudspeaker  system  that  is  ruler-flat 
across  a  wide  band-width  and  yet 
remains  a  relatively  easy  load  for 
any good amplifier system.

Many loudspeaker engineers aim for 
a sound that could be described as 
‘cosy’. It is easy to listen to for short 
periods and immediately impressive 

in  demonstration.  Most  notably 
though from the engineer’s point of 
view,  it  hides  many  kinds  of  small 
frequency  response  abhorrations. 
Aside  from  not  reproducing  the 
original  recording  faithfully  though, 
this  can  be  inclined  to  cause 
longer-term  listening  fatigue.    A 
cosy  respnose  is  nowhere  near  as 
accurate,  revealing,  transparent  or, 
in the long term, enjoyable as a well-
balanced flat response.

Even  small  abhorations  in  the 
frequency response have a profound 
effect  on  the  overall  loudspeaker 
balance.  Peaks  in  the  response 
spectrum  can  mask  surrounding 
frequencies  leading  to  a  loss  of 
transparency and a ‘blurring’ of the 
soundstage.  Because  we  engineer 
our own drive units and cabinets in 
complete  synergy  to  the  rest  of  the 
design  process,  we  control  every 
aspect  of  our  drivers’  performance 
and can get much closer to an ideal 
performance.
