Sky System One: 2.1 System, (2) SAT 6.5 MK II & (1) Sub 12

Sky System One is the original manifestation of Blue Sky’s unique approach to accurate, full-range monitoring. Each 100-Watt bi-amplified SAT 6.5 MK II satellite speaker employs a 6.5" hemispherical driver and 1" Neodymium tweeter with a dual concentric diaphragm and integral wave guide. Bass management and level control are incorporated within the SUB 12 subwoofer which features a single long excursion 12" woofer and a 200-Watt, low distortion power amplifier.

Employing Blue Sky’s proprietary computer-optimized crossover and bass management networks, the Sky System One delivers seamless full-range audio from the subwoofer to the main monitors with smooth on and off-axis frequency response. In addition, the Sky System One is THX pm3® approved for use in THX pm3® certified studios. By adding three additional satellite speakers and a Blue Sky Bass Management Controller, the system is easily expandable for use in a 5.1 surround sound monitoring setup.

Application Notes

Sky System One delivers accurate, full-range nearfield monitoring in a wide variety of 2.1, 5.1 and beyond, surround sound applications. As is the case with all Blue Sky monitoring systems, Sky System One made extensive use of the proprietary BOO™ (Binary Organic Optimization) technology in the development of the crossover and bass management networks to ensure a seamless spectral experience in ‘real world’ monitoring environments.
