The ATC SCM40 is a high-performance floorstanding loudspeaker designed for accuracy, speed, and transparency. It is fully developed and built in-house by ATC. As a result, it delivers clean, detailed, and natural sound across the full frequency range.
In addition, the SCM40 combines a three-way driver design with a flat impedance curve. Therefore, it offers strong performance while remaining easy to drive with a wide range of amplifiers.
Three-way ATC driver system
The SCM40 features a 25mm soft dome tweeter with precision wave guide, a dedicated ATC soft dome midrange driver, and a 164mm bass driver. As a result, it delivers smooth highs, natural vocals, and tight, controlled bass.
Optimized motor design
Each driver uses a large, optimized motor assembly. In addition, this improves control and reduces distortion. Therefore, the speaker maintains clarity and accuracy even at higher volumes.
Amplifier-friendly performance
Thanks to its flat impedance curve, the SCM40 is easy to match with many amplifiers. As a result, it provides stable and consistent performance in different systems.

“Given a serious source and recording the new ATC SCM40 is superb – I know of no price rivals that give this level of accuracy, speed and insight…it’s capable of a level of transparency you normally only expect from loudspeakers at three or four times its price.” Hi-Fi Choice, October 2014 Review
