ATC SCS140iW Pro - Dual 12" Active Subwoofer (In-Wall)

ATC SCS140iW Pro - Dual 12" Active Subwoofer (In-Wall)

The ATC SCS140iW Pro is a high-performance, dual 12” active subwoofer designed for flush in-wall (soffit) installation in large control rooms. It pairs seamlessly with SCM200AiW Pro main monitors for stereo, multichannel, and immersive audio setups. Its cabinet width matches the SCM200 for a clean, integrated aesthetic when installed together. The SCS140iW Pro also complements smaller monitors where extended bass and high SPL are required.
