   Windows-10 radio's or speakers?   
      
   I think you can post this question in an audio or a radio newsgroup   
   e.g.  uk.tech.broadcast    (for radio signals)   
   maybe  rec.audio.tech  ?  ( I do not read this group)   
      
   But you got some good answers here!   
   (probably from the repair or design groups)   
      
   If you change the wires of one speaker you get a 180 degree   
   difference on all audio frequencies.   
   If from two speakers at the some radio (left and right), one is wrong   
   connected, you can hear that at exactly the middle between the speakers   
   where there is a fase-out for all audio frequencies.
