 The ATC SCM25A Pro Mk2 is a compact, three-way active stereo monitor that delivers exceptional studio-grade performance in a modest footprint. It’s built around ATC’s handcrafted 6.5″ bass driver, 3″ soft-dome midrange, and upgraded SH25-76S dual-suspension tweeter—designed entirely in-house in England—to extend the high-frequency range while significantly reducing distortion  . Each of the drivers is powered by its own class A/B amplifier (150 W bass, 60 W mid, 32 W high), ensuring powerful and precise reproduction with ultra-low distortion.

Engineered for clarity and accuracy, the monitor features fourth-order Linkwitz-Riley crossovers with all-pass filters for seamless phase integration, user-adjustable input sensitivity and bass boost, plus FET peak limiters to prevent clipping—all designed to help you make faster decisions with rock-solid translation outside the studio.

Small yet mighty, the SCM25A Pro Mk2 delivers extended bass, pristine midrange, and vivid highs, making it an ideal choice for nearfield critical listening in music production, mixing, and immersive audio environments.
