Know before you buy
The infinite baffle design uses a sealed cabinet, which provides a tighter, more controlled transient response compared to ported designs. This results in more accurate, 'honest' bass reproduction that is ideal for critical monitoring and mixing.
Yes, the subwoofer is compatible with a wide range of professional active monitors. Its balanced XLR inputs and flexible crossover controls allow you to integrate it into most studio setups, though it is specifically voiced to complement the ATC active monitor range.
Absolutely. The SCS70 PRO is designed for high-performance LFE channels and immersive audio setups. Its ability to daisy-chain multiple units makes it highly scalable for complex, multi-subwoofer configurations required in professional post-production environments.
The 300-watt Class AB amplifier is designed for precision and low distortion rather than raw power alone. With a peak SPL of 116dB, it provides ample headroom for most professional control rooms and critical listening spaces.
The subwoofer features three selectable low-pass filter frequencies, along with phase and polarity controls. These allow you to fine-tune the crossover point to ensure a seamless transition between your main monitors and the subwoofer.
The SCS70 PRO measures 18 x 22 x 20 inches and weighs 97 lbs. Because it uses a sealed enclosure, it is relatively compact for its performance class, but you should ensure your floor or stand can support its significant weight.
