Blue Sky introduces two new components to its studio monitor line starting this April: the 400W Push-Pull SUB 212 active subwoofer and the 300W compact Mid-Field SAT 8 monitor.

Renowned worldwide for precision, with a full frequency response, Blue Sky is excited to introduce two particularly important components to its complete studio monitor line: the 400W Push-Pull SUB 212 active subwoofer and the 300W compact Mid-Field SAT 8 satellite. The SUB 212 is designed to be an integral part of a monitoring system, allowing a studio monitor like the SAT 8 to be positioned for the best imaging while the SUB is positioned for optimal low-frequency response. Freeing the studio monitor (satellite) from the effort of reproducing low frequencies means that the uncompromising "sealed-box" design combined with sophisticated bass management electronics ensures a tight connection between the SAT and SUB. When combined, the SAT 8 and SUB 212 provide full-frequency response monitoring with stunning clarity and precision.
"Our customers have asked for a powerful system similar to the Sat 12 and Sub 15, but in a smaller package," said Blue Sky Vice President Chris Fichera. "The Sat 8 and Sub 212 will address these applications"
About SUB 212
The BlueSky SUB 212 is a 400W active push-pull "sealed box" subwoofer with two 12" drivers. It features a frequency response of 25Hz to 200Hz, +/-3dB. Additionally, the SUB 212 includes sophisticated bass management electronics for a 2.1 system with a 4th order low-pass filter at 80Hz Linkwitz-Riley and a 2nd order high-pass filter at 80Hz, perfectly suited for the response of the SAT 8 (the SUB 212 is also compatible with SAT 12, SAT 6.5, and SAT 5).
The unique "push-pull" configuration of the SUB 212 is designed not only to increase output level but also to reduce distortion. A push-pull subwoofer uses 2 drivers: one mounted with the diaphragm facing outward, and the second mounted behind the first, with the magnet facing outward. By using two drivers, the maximum power is doubled, while the push-pull configuration reduces harmonic distortion. Normally, in a conventional design, at very high output levels, secondary harmonic distortions dominate the distortion spectrum of most subwoofer drivers, a problem caused by the asymmetric operation of the driver's suspension and magnetic structure. In other words, the driver's output is different when the diaphragm moves toward the magnet compared to when it moves away from the magnet.
The Push-pull operation reduces harmonic distortion through an intelligent physical method. As mentioned above, push-pull uses two drivers, one mounted opposite the other. The driver mounted at the bottom has its magnet facing outward and is electrically "driven" out of phase by the front driver, which keeps both drivers acoustically in phase. When the diaphragm of the front driver moves away from the magnet, the diaphragm of the other driver moves in the opposite direction, toward the magnet. When the outputs of the two drivers combine, their harmonic distortions cancel each other out, significantly reducing the overall distortion of the subwoofer.
About SAT 8
The Blue Sky SAT 8 is a compact three-way mid-field monitor, tri-amplified with a maximum power of 300W, featuring an 8" high-excursion low-frequency driver, a 4" low-distortion mid-frequency driver, and a 1" dual-ring membrane tweeter with an integrated waveguide. To reduce destructive cabinet reflections, Blue Sky has developed and incorporated the "Multi-Aperture Acoustic Diffraction Absorber" in the SAT 8, which helps maintain a pleasant frequency response at mid and high frequencies without the need for a horn to guide the frequencies.
The SAT 8 features a special low-distortion 100W amplifier for the 8" woofer, another low-distortion 100W amplifier for the midrange, and yet another 100W for the tweeter. The SAT 8 effortlessly produces clean and precise sounds with a frequency response of 80Hz to 30kHz +/-3.0dB (200Hz to 15kHz +/-1.5dB), being compatible with SUB 15 Universal, SUB 212, SUB 12, and BMC (Bass Management Controller). The rear panel offers control for "full space" operation (room placement) or "half space" (wall-mounted), potentiometers for adjusting high, mid, and low frequency levels individually, as well as controls for various amplification variables.
The SAT 8 is designed to operate both vertically and horizontally, thanks to the ability to rotate the plate on which the midrange driver and tweeter are mounted.
