The ATC SCS70iW Pro is a high-performance, 12-inch (300mm) active subwoofer designed specifically for flush-mount (soffit) installations. By combining ATC’s legendary acoustic engineering with a shallow-depth cabinet, the SCS70iW Pro provides the perfect low-frequency extension for professional studios where floor space is at a premium and a clean, integrated aesthetic is required.
Acoustic Precision: Features the ATC hand-built, high-excursion SS75-314SC 12” driver.
In-Wall Optimized: Specialized cabinet design with reduced depth for seamless soffit mounting.
Remote Power: Driven by the dedicated R1-300 7U/19” rack-mount amplifier to keep electronics accessible and cool.
Advanced Control: Full user-adjustable Level, Low-Pass Frequency, and Phase settings for perfect room integration.
Versatile Integration: Ideal for stereo, multi-channel surround, and Immersive Audio (Dolby Atmos) formats.
British Craftsmanship: Hand-built in England and protected by an industry-leading 6-year warranty.
The SCS70iW Pro delivers an exceptional balance of high SPL capability and low-frequency cut-off without the distortion typical of smaller subwoofers.

“The SCS70iW Pro is the definitive solution for engineers requiring the transparency of a full-sized ATC subwoofer within a space-saving, soffit-mounted architecture.”
Unlike standard active subs, the SCS70iW Pro uses the R1-300 Remote Rack Mount Amplifier. This 7U/19” unit allows you to manage power and calibration settings from your equipment rack rather than reaching behind a wall-mounted cabinet. It also features remote muting via a standard 1/4” latching footswitch, essential for A/B testing your mix with and without the sub.
Whether you are building a new Dolby Atmos suite or upgrading a stereo room, the SCS70iW Pro provides the “Low Frequency Effects” (LFE) channel precision necessary for modern cinematic and music production. Its sealed cabinet design ensures a tight, musical low-end that translates perfectly across all playback systems.
