1.  INTRODUCTION 

 

Thank you for selecting the German Physiks PQS 402 for your audio system.   It uses an array of two 
DDD drivers to cover all frequencies above 220Hz.  The low frequencies are handled by a system using 
two 10 inch drivers combined with four 8 inch passive radiators.  The Loreley is entirely handmade and is 
built and tested by highly skilled technicians at our factory in Germany. 
 
Every step in the design and manufacture of this product has been dedicated to producing a loudspeaker 
that will provide a lifetime of musical enjoyment.   
 
We  strongly  recommend  that  you  read  this  manual  before  you  attempt  to  use  the  loudspeakers.    The 
supplying audio dealer is responsible for assembling and setting up the loudspeakers.  This should not 
be  attempted  by  the  customer.    Information  on  these  topics  contained  in  this  manual  is  intended  for 
general use only.   
 
 

 2.   UNPACKING YOUR LOUDSPEAKERS 

 

NOTE: 

The  customer  should  not  attempt  to  assemble  the  loudspeaker.  
This will be done by the supplying audio dealer. 

 

The  crates  and  their  contents  are  heavy.  To  avoid  injury,  please 
ensure  that  2  people  are  available  to  unpack  and  position  the 
loudspeakers. 

 
The PQS-402 is supplied in 3 crates.  Before opening them, please inspect them for damage.  If you see 
any damage to the crates, please contact the supplying audio dealer immediately and provide them with 
a full description of the damage.  Do not attempt to unpack the loudspeakers until you have spoken with 
the dealer and have been advised how to proceed. 
 
The woofer module assemblies for the left and right channels are packed in separate crates which are 
marked “left” and “right” on the outside.  Take care not to mix components from these two crates up. The 
two DDD towers are packed together in the third crate.  
 
Please  retain  all  of  the  packing  as  you  will  need  this  should  it  be  necessary  in  the  future  to  ship  the 
loudspeakers.    Should  you  need  to  return  the  loudspeakers  to  the  factory,  you  must  use  the  original 
packing.    The  use  of  any  other  packing  may  result  in  the  loudspeakers  sustaining  damage  in  transit.  
Such damage is not covered by the warranty.  Should you require replacement packing, please contact 
your German Physiks dealer, the national distributor or the factory directly.
