• Features

• a subwoofer that works...
  
• Bass Extension
  
• Down to below 30Hz (typical in-room response down to 20Hz)
  
• Compatible
  
• The SUB 12 includes full 2.1 bass-management circuitry that ensures seamless summation when used with Blue Sky's SAT 6.5 / SAT 6.5 MKII, SAT 5 / SAT 5 MKII and SAT 12. Additionally the SUB 12 is also fully compatible with any THX pm3 approved nearfield monitor (visit www.thx.com for more information).
  
• Sealed Box Design
  
• No port = no port noise = better transient response = greater SLAM!
  
• Easy Setup
  
• Straight forward with excellent customer support, if needed.
  
• is that so...
  
• Q: Can you explain the concept of 2.1?
  
• A: Think of it as removing the LF source from your existing 3–way system and playing it back through a separate box (a subwoofer). Although still part of an integral system, the subwoofer can be placed away from your mid/hi” speakers to provide the best bass response the room can offer.
  
• Q: Why do I want a system that uses a subwoofer?
  
• A: It’s about real low-end, the kind you can feel. Your recording system is able to record it, the audience will want to hear it and you deserve a true fullrange monitoring system that can accurately reproduce it.
  
• Q: Won’t I perceive a hole in the frequency response because of the subwoofer?
  
• A: No! The use of a sealed cabinet design results in an extremely flat frequency response.
  
• Q: Why don’t your speakers use ports or passive radiators?
  
• A: Ports and Passive radiators can increase the efficiency of a speaker system, but because they resonate, they also negatively impact the transient response of the system. Ports can also add noticeable distortion and noise.
  
• science fiction / fact
  
• Fiction: I don’t need to hear what is going on below “X”Hz
  
• Fact: If you can’t hear it, you can’t mix it—only when you have a full-range monitoring system will you be able to make informed creative decisions. So, don’t settle for the kind of low frequency performance that was around 20 years ago—aspire to that which surpasses what is expected today.
  
• Fiction: I have heard that subs don’t work well in small rooms?
  
• Fact: If you want more consistent LF performance, greater LF extension and mixes that translate better, there is no easier way to reach these goals than to use a Blue Sky subwoofer—especially in a small room!
  
• Fiction: Aren’t subs hard to set up?
  
• Fact: With literally thousands of Blue Sky systems installed in studios around the world, we have developed a simple methodology to help you get it right. And, if you have any questions, we are here to help.
