1. SUB 15 Universal

Introduction

Blue Sky is a philosophy. We design each product to represent the highest
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 15 Universal 1000-Watt
subwoofer. The SUB 15 Universal is a sealed box subwoofer, designed around
a 15” forward-firing driver with a massive cast aluminum frame, dual 2.5” voice
coils - which has almost 2.36” of excursion (peak to peak) and features an
enormous 20+ Lbs. motor structure - total driver weight 36 Lbs. (

see figure 1

for a detailed driver cutaway drawing). One of the SUB 15 Universal’s unique
features  is  a  switchable  low  frequency  response  characteristic,  of  either
30Hz  to  200Hz  +/-3dB  or,  in  “extended  LF  mode”,  20Hz  to  200Hz  +/-3dB
(anechoic).  The  extended  mode  is  ideal  for  large  rooms  that  don’t  exhibit
the  room  gain  phenomenon  of  smaller  sealed  spaces.  In  addition,  the  SUB
15  Universal  also  has  built-in  2.1  bass  management  electronics  with  both  a
4th order 80Hz Linkwitz-Riley low-pass filter and a 2nd order 80Hz high-pass
filter  that  is  compatible  with  the  SAT  12’s  bass-managed  input  and  is  also
compatible with the SAT 6.5 and SAT 5.

The SUB 15 Universal is also the second subwoofer from Blue Sky which
allows you to add true low frequency extension to your existing nearfield and
mid-field monitors. To accomplish this, the SUB 15 Universal includes dual
independently tunable, state variable, high pass and low pass filters (50hz to
160Hz) with 4th order slopes.

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.

Thank you for choosing Blue Sky!
