Loudspeaker positioning. 

 
There is no objective criteria that can be used to state precisely  where loudspeakers 
should be positioned. Should any individual or company suggest that there is, they 
should be regarded as special people and treated with a great deal of caution. In the 
global scenario our loudspeakers are driven by unique systems that are selected by the 
owner because of particular virtues. Every listening room is as individual and  unique in 
character as the owner. Compound this complex picture with the combination of 
different equipment Consider the changeability of rooms, if the room is dressed with 
heavy curtains simply changing the curtains position can alter the whole balance of the 
system. The only rule is that there are no rules. Like producing good wine it is the goal 
that is the only guide. The owner is the pivot in this subtle balancing act. 
 
The goal of high performance audio systems is accurate reproduction. The information 
be it in groove or pit form should be transcribed, amplified and converted back into 
sound energy without the additional views of the audio equipment designer being 
combined with that translation process.  
 
When one considers this and finally that  what one actually hears is a unique experience 
and subject to the realms of subjective evaluation  It is for these reasons that when 
making recommendations about positioning loudspeakers it is only possible for very 
general advice to be given.  
 
In order to make the task of positioning the loudspeakers less complex we would like to 
make the following suggestions. That most valuable commodity time is the most 
important ingredient in this process. Be prepared to make small changes over longer 
periods of time.  
 
Chose four musical passages that you are familiar with that can fulfill the following tests. 
They should all be stereo recordings. 
Select one with a distinctive and easily heard human voice. Spoken voice is ideal. 
Select one passage with a full orchestra like The Pines of Rome. 
Select one that is very emotional for you. 
Select one that has a strong rhythm as in the case of dance music. 
  
You should appraise the performance of the loudspeakers according to 

your needs

 

based upon the tests above.
