Danger:

 

When using a distance rod mounted on subwoofer/s, the loudspeaker should never 

be  heavier  than  the  subwoofer/s  itself.  The  longer  the  distance  rod  is  extended,  the  greater  the 
counterweight  should  be.  Secure  the  subwoofers  to  each  other  with  straps  and/or  to  the  ground/
suitable platforms! Check the stability in every case! 

 

DANGER!
