Product Information
Shipping & Returns

The ATC SCS120iW Pro is a high-performance in-wall active subwoofer designed for studios that require serious low-frequency capability without sacrificing room layout or floor space. Built around ATC’s hand-made 375 mm long-throw sub-bass driver, it delivers clean, extended bass down to around 20 Hz with the same accuracy, speed and neutrality found in ATC’s free-standing subs.

To support in-wall installation, the SCS120iW Pro uses a remote 300 W Class A/B MOSFET amplifier, supplied in a separate 7U rackmount chassis for flexible placement outside the wall cavity. The sub cabinet itself is a sealed, shallow-profile design optimised for flush mounting in walls or soffits, making it equally at home in professional mix rooms, mastering suites, post-production environments and immersive monitoring systems including Dolby Atmos.

System tuning is highly flexible. Selectable low-pass filters at 50 Hz, 65 Hz, 80 Hz and 320 Hz allow for seamless integration with a wide range of monitors, with a filter bypass option for external control. The onboard alignment tools include a stepped level control, gain trim, polarity invert and a continuously variable 0–180° phase control, giving precise matching to the main loudspeakers. Balanced XLR inputs and link outputs make system wiring straightforward, and the remote mute function via footswitch supports professional workflow setups.

With its compact in-wall form factor, robust ATC engineering, and deep, controlled low-frequency performance, the SCS120iW Pro is an ideal foundation for high-end monitoring systems where space efficiency and accuracy are equally critical.

• 15" ATC hand-built sub-bass driver
• Remote 300 W Class A/B MOSFET amplifier in rackmount chassis
• Shallow sealed cabinet for flush in-wall or soffit installation
• Selectable low-pass filters or bypass
