Blue Sky SUB 12 Subwoofer

The Blue Sky SUB 12 was specifically designed to complement the SAT 6.5 and SAT 6.5 MK II Satellite speakers. Featuring a cast aluminum frame, 12" forward-firing driver with 2" voice coil, the SUB 12 has a dedicated 200-watt amplifier with a frequency response of 30 Hz- 200 Hz +/– 3 dB (anechoic) and a typical response of 20Hz to 200Hz (3000 Cubic Foot Room).


In addition, the SUB 12 has a built-in 2.1 bass management system with a 4th order, 80 Hz Linkwitz-Riley low-pass filter and 2nd order 80Hz high pass filter for the satellite. Rear panel functions include: Right/Left In and Out; SUB In and Out (for connecting multiple subwoofers); Mute and Phase switches; SUB Gain & Power LED; Power switch; and Slo-Blo Fuse. Measuring 18"H x 15"W x 20"D and weighing 62 lbs., the SUB 12 features MDF construction with four recessed 1/4" x 20 threaded inserts for either spiked or rubber feet.


The SUB 12 is also fully compatible with Blue Sky's I/ON, SAT 5 / SAT 5 MKII and SAT 12*. Additionally the SUB 12 is compatible with any THX pm3 approved nearfield monitor.



Blue Sky Sky System One SUB 12 Features :

          o Bass Extension
            Down to below 30Hz (typical in-room response down to 20Hz)

          o 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.

          o Sealed Box Design
            No port = no port noise = better transient response = greater SLAM!

          o Easy Setup
            Straight forward with excellent customer support, if needed.



* NOTE: When the SUB 12 is used with the SAT 12, multiple SUB 12s should be used.
