ratio possible of performance to cost, providing the highest value added to 
our customers.

We will continually seek out opportunities to utilize the talent of the Blue Sky 
team to realize this philosophy. Our customer’s value requirements will always 
be our prime focus, and only those products that achieve our performance 
value ratio will earn the right to carry the Blue Sky logo.

To  that  end  we  are  proud  to  introduce  the  Blue  Sky  SUB  8  Universal,  the

can  be  combined  with  Blue  Sky’s  SAT  5  to  form  the  highly  acclaimed  and 
award winning ProDesk™ 2.1 Monitoring System.

We  hope  that  this  subwoofer  brings  you  years  of  accurate  and  problem 
free  operation.    We  ask  that  you  take  the  time  to  read  this  manual,  register 
the  product  and  visit  our  website  for  any  updated  information  regarding 
this product.  If you have any questions please don’t hesitate to contact us.
