What reviewers think
Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.
How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

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.

Vandersteen
IT'S ALL IN THE TIMING. The Model Seven XTRM continues a tradition of pushing time-and-phase correct audio reproduction to the ultimate extreme. With new pistonic side-firing drivers matched to the patented mid-range and tweeter, the XTRM brings further clarity and harmonic accuracy in a way that surprised the designers and the expert listening board. Give yourself a treat and take a listen soon. Full XTRM updates are available to the original owner within the USA, and the cost is $30,051 to $45,633, depending on the vintage of your Model Seven.
Vandersteen Audio is distinguished by its time and phase coherence in speaker design, where all drivers move in unison through their first-order crossover design and Perfect-Piston drivers made of carbon-fiber and balsa wood. The brand's speakers feature a minimum baffle approach to reduce reflections, while focusing on high-quality internal components over elaborate cabinet designs, with models like the Seven XTRM offering precise bass response customization through adjustable trim pots.
Expand Details
Our Summary

Product Considerations
- Sensitivity is relatively low at 85dB, requiring a powerful amplifier to achieve its full potential
- Requires careful rake angle adjustment for optimal performance
- Bi-wire capable, the mandatory HP-7 filter costs extra
Comparisons (according to reviewers)
- Vs KEF KC-62 subwoofer: Both use counter-opposing force woofers to stop cabinet movement
Takeaway: The Model Seven XTRM is a technologically innovative speaker designed for music lovers. It offers powerful bass, harmonic beauty, and exceptional tonal realism, making it a worthwhile investment for those seeking a high-fidelity audio experience.
