Description

The ATC SCS240iW Pro is a reference-grade, in-wall active subwoofer system engineered for professional studios requiring precise, extended low-frequency response in immersive audio environments. Designed for seamless integration alongside ATC's SCM300AiW Pro main monitors, the SCS240iW Pro delivers deep, accurate bass performance with high SPL capability which is ideal for Dolby Atmos®, multichannel mixing, or high-end stereo mastering rooms.

The design allows the sub to be flush-mounted into studio walls, with recessed input panels for a clean aesthetic.
