Assembly and disassembly – groundstack operation 

 

Using  the  stacking  frame  (reversed  flying  frame  with  extenders),  a  stacked 

Galeo array of up to 6 elements is possible without further ballasting. Insert the 

extenders  into  the  holes  in  the  flying  frame  and  secure  these  using  ball  lock 

pins according to the assembly instructions. 

The  floor  space  must  be  skid-proof,  clean,  even  and  sufficiently  sustainable. 

Due to possible wind force, the top edge of the array must not be higher than 

5m above ground level. Observe the structural analysis certificate.  

Larger  arrays  are  possible  of  course,  but  these  must  then  be  braced  and 

secured accordingly in order to prevent toppling in windy conditions (separate 

certificate is required!).  

  

 

 

 

Do  not  assemble  groundstacks  in  areas  that  are  accessible  to  the  public  or 

where they can possibly even be knocked over in a panic situation.    

 

 

 

Using  the  stacking  device  on  the  top  of  the  Galeo  Sub,  the  Galeo  can  be 

mounted  directly  onto  the  Galeo  Sub  without  the  need  for  further  stacking 

frames  or  similar  devices.  Stack  the  woofers  first  and  connect  them  via  the 

fittings. Then stack the Galeo units on top of the woofers.   

 

 

 

 

The  structural  analysis  certificate  contains  the  following  cases  for 

stacked 

operation at open-air events and up to wind force 8: 

 

up to 6 Galeo on 1 Galeo Sub 

 

up to 6 Galeo on the groundstack frame with extenders 

 

Galeo groundstack, short extenders at front, 
long extenders at rear
