ATC SCS70 Pro 12" Powered Studio Subwoofer

Low frequencies reveal the difference between simply hearing a mix and truly understanding it. The ATC SCS70 Pro is a professional powered studio subwoofer engineered to extend monitoring systems with the same accuracy, low distortion and dynamic performance that define ATC’s renowned monitor range. Built around a hand-crafted 12" ATC SS75-314SC high-excursion driver and powered by a 300W discrete MOSFET Class A/B amplifier, the SCS70 Pro delivers deep, controlled low-frequency extension down to 22Hz while maintaining exceptional clarity and transient response. Designed for stereo, surround and immersive audio formats, including Dolby Atmos, it provides the low-frequency foundation required for confident critical listening in modern professional production environments.

ATC Low-Frequency Precision and Dynamic Performance

At the core of the SCS70 Pro is ATC’s proprietary SS75-314SC 12" driver, developed to deliver deep bass extension, substantial output and remarkably low distortion. Its sealed enclosure promotes fast transient response and accurate low-frequency reproduction, helping engineers evaluate kick drums, bass instruments and low-end effects with greater confidence. Producing up to 110dB continuous SPL and 116dB peak output, the subwoofer delivers powerful low-frequency energy while preserving control, detail and tonal balance. Whether monitoring music production, film soundtracks or immersive audio content, the SCS70 Pro maintains the accuracy required for critical decision-making.

Flexible Integration for Professional Monitoring Systems

The SCS70 Pro is designed to integrate seamlessly with ATC active monitors and other professional monitoring systems. User-adjustable gain, level, phase, polarity and low-pass filter controls allow precise system alignment for a wide range of room configurations and monitoring applications. Balanced XLR inputs and outputs provide clean signal routing, while selectable crossover frequencies support optimized integration with nearfield, midfield and surround monitoring setups. Remote muting via an optional latching footswitch adds workflow flexibility during critical listening sessions, system calibration and mix evaluation.

Hand-Built Reliability for Modern Studios

Like all ATC professional products, the SCS70 Pro is hand-built in England using premium components and rigorous manufacturing standards. Its convection-cooled discrete MOSFET Class A/B amplifier eliminates the need for cooling fans, ensuring silent operation in critical listening environments. Equally suited to stereo mixing rooms, post-production facilities and immersive audio installations, the subwoofer is built for years of reliable service and consistent performance. Backed by a six-year warranty and ATC’s longstanding reputation for engineering excellence, the SCS70 Pro subwoofer delivers the depth, accuracy and low-frequency confidence demanded by modern professional monitoring systems.
