What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

SCM7 MK3
- Positioning: The entry-level model in ATC's loudspeaker lineup.
- Description: Features a compact design and precise sound, with a 25mm soft dome tweeter and a 125mm mid-bass driver. Compared to the SCM19, it offers a smaller footprint, making it ideal for small rooms or desktop setups, but it lacks the larger bass driver and higher sensitivity found in the SCM19.
SCM19
- Positioning: A mid-range model in the Entry Series, offering a balance between performance and size.
- Description: Features an "SL" spec bass driver and 75mm integral soft dome, providing excellent phase coherence and bass response. It offers a more robust soundstage than the SCM7 MK3.
SCM19A
- Positioning: An active version of the SCM19, positioned as a higher-end option within the Entry Series.
- Description: Includes an on-board 182-watt Class A/B bi-amplifier, delivering enhanced sound clarity and power. It uses active crossover filters, unlike the passive SCM19, which requires external amplification.
SCM40A
- Positioning: The groundbreaking flagship model of the Entry Series, offering the most advanced features and performance.
- Description: Equipped with a tri-amplifier system and a 164mm bass driver, providing exceptional sound quality and dynamic range. It surpasses the SCM19A with its additional mid-range driver and higher power output.
