B. Connection in a 2 channel Stereo system : 
 

When used in a stereo system, a Logos Sub may be used to complement in low 
frequencies a pair of Logos Mini or Logos speakers, or even a pair of Epilogue 1 
speakers. You may use one or two subwoofers : 
 

  If you use 2 subwoofers connect the right channel to the right subwoofer and the 

left channel to the left subwoofer. Try to align the distance of the subwoofers to 
be identical to the distance of the main speakers from the listening point. If you 
use analogue connections, always leave a short-circuiting plug on the unused 
analogue input. 

  If you use only one subwoofer in analogue, connect one analogue input of the 

subwoofer to the right channel and the other to the left channel of the 
preamplifier. 

  Frequency adjustment : see the above section. 

 

 
6. RUNNING-IN FOR THE LOGOS SUB 

 
 

The Logos Sub, like any other top quality speaker needs several days playing music 
before providing the top sonic quality it is built to provide.  
 
The few first hours can be very frustrating for a demanding listener.  
 
Do not hesitate to let it play quite loud some time before attempting any real system 
tuning or position adjustment. 
 
 
 
 
 

7. CLEANING THE LOGOS SUB 

 
 

To clean the metal case of the speaker, you can use a wet cloth. Always use a very 
soft cloth to avoid scratching the surface. 
 
The identification plate is gold plated. Simply clean it with a soft cloth, without any 
chemical solution.
