Our take on the brand
Used
ATC
What if you spend a bit more?

The SCM50 ASL (active) and SCM50 SL (passive) are designed to perform at their best in the recording studio or at home with the finest quality hi-fi equipment. The monitors' ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver. However, recent modifications that include the new ATC SH25-76S tweeter and enhanced port profile have brought about further improvements to all performance parameters.
Each drive unit in the active model has its own dedicated and individually matched MOS-FET amplifier, while the 234mm/9″ bass driver incorporates ATC's unique Super Linear Magnet technology. Our active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion. Like the HF, mid and bass drivers, all electronics are designed and manufactured in-house to create a no-compromise active system.
In passive form, the SCM50 SL provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the frequency range. Speakers are supplied with stands and fabric wrapped grills.

Our Summary
Product Strengths
- ATC designs and builds every drive unit in-house, including voice coils, crossovers, and active amplification, allowing for complete control over every loudspeaker design decision
- In the active version, a more clearly defined soundstage has clearer, more well-defined individual elements, where everything pops out more from the background
- The active version has more energy, drive, and a more vivid overall presentation, resulting in a more tactile, energetic, and higher resolution sound
- The SCM50's woofer has an enviable ability to resolve textures and timbral colors, capably rendering the skins of bass drums, the flutter of tom-toms, or the dark voicing of orchestral bass viols as bows are dragged across their strings
- The SCM50 has an almost eerie immediacy that seems to glean the intent of the musician before their bow touches the string or a note escapes their lips, making piano reproduction breathtaking
- Connectivity is limited to a single XLR input, which may require adapters for single-ended sources
Product Considerations
- The active version is heavier than the passive version
- The owner must manually turn each speaker on and off, as there is no trigger or auto startup circuit
- The active version may pose challenges for owners of subwoofers needing high-level wiring connections, although workarounds exist
- Careful attention must be paid to positioning a pair of SCM50s, as the full-bandwidth—ported design means that placing them too close to a boundary wall will result in bass bloom
Comparisons (according to reviewers)
- SCM50 wins hands down over PureAudioProject Duet 15s for resolution, clarity, and dynamic shading
- The active version excels over the passive in solidity of soundstage, neutrality, and ultimate detail retrieval
Takeaway: The ATC SCM50 offers exceptional sound quality, whether in its active or passive configuration, thanks to ATC's engineering and in-house design. The ATC SCM50 is a choice that will bring musical joy for years to come.

Our take on the brand

Our Summary
Product Strengths
- Improved phase or timing enhances stereo imaging and creates a clearer overall picture
- The active version removes a 'filter' between the listener and the original source, making music more intense, energetic—and vivid—resulting in higher resolution audio
- Vocals are presented bigger, taller, grander in scale, with more detail and insight—most impressively—how natural they sound
- Dynamics and micro-detail are impressive, expressed in ambient noises, breaths of singers—and fingernails of guitarists
- ATC monitors are designed to provide the best from both areas: detailed and accurate with limited dynamic range, and professional monitors with great dynamic range and fidelity
Product Considerations
- ATC speakers like to be played loudly, like the original event, and live music isn't created at volume levels for going to sleep; if you like to be lulled by your audio system, look elsewhere
- The speakers get quite a bit heavier with the amplifier packs in them
- You have to manually turn each speaker on and off, as there is no trigger system designed into them
- System organisation and cabling has to be considered because it might be quite different to how you have things wired now in a passive system, and this could mean extra cost on top
- If you don't have an amplifier to connect your high level wiring to, you would need to either use a preamplifier with an output you can use, or maybe use a splitter on the balanced cable
Comparisons (according to reviewers)
- Vs ATC SCM50 PSL (Passive): The active SCM50 ASL is more vivid overall, while the passive is more 'cuddly'
- Vs ATC SCM20: The 50s are more like the same person—only bigger
Takeaway: The SCM50 ASL offers a technically better and more vivid listening experience due to its active design, bringing listeners closer to the original sound. If one wants a speaker for serious listening and appreciate high-resolution audio, this could be a great choice.

Our take on the brand

Our Summary
Product Strengths
- Most affordable way into the true 800 series form factor, with the solid aluminum turbine head and the fully curved matrix-braced cabinet
- Features a one-inch diamond dome tweeter, which is a standout strength
- Midrange and vocal region from the Bowers favor a leaner, more technically accurate sound, going for outright clarity, and vocals sound particularly clear and clean
- Bases have casters integrated or built into them, making them easy speakers to move around for optimal positioning, and integrated spikes can then be used to securely position them
- Show-stoppingly gorgeous and sound simply fantastic
Product Considerations
- A much fussier speaker in every regard and require more thought and work to get the sound balance right
- Possible to come across maybe a little bit too lively in the treble
- Amplifier power, quality, and capability is hugely influential—hugely important for these speakers
- Due to their revealing nature, they don't play particularly well with poorer recordings such as metal and older rock
- Tweeter can get fairly harsh when the volume is turned to the extreme, pushing 90+ db for louder music
Comparisons (according to reviewers)
- Bowers & Wilkins are a much fussier speaker in every regard than the Mission 770
- Paradigm Persona 5H is a little more "liquid" sounding
- Wilson Audio SabrinaX's finish is superior to that of the Bowers & Wilkins, dynamic, easy to drive, with a very familiar and very resolute sound
- Bowers & Wilkins 803 D4s are refined like an Aston Martin, and Tekton Ulfberhts are more like a Corvette C8
- Bowers & Wilkins 805D4 lacks the midrange prowess that the 803 has, and will most definitely need a subwoofer for even mild extension into bass
Takeaway: The 803 D4 speakers offer a fantastic listening experience with clear vocals and a grand soundstage, making music more engaging. They are an investment that can potentially improve over a long period of time through system upgrades and continued optimization.

Video review
Our take on the brand

Our Summary
Product Strengths
- Excellent bass extension and higher dynamic range due to its larger size.
- The cabinet is designed to maximize bass performance using segmented inner chambers.
- A Beryllium tweeter is precisely positioned at the best height for listening, and the midrange is placed above the tweeter to time-align the drivers for coherency at the listening position.
- The midrange driver has Tuned Mass Damper technology, similar to what is employed in racecars and seismic building stabilization, allowing the driver to perform more consistently without losing performance.
Product Considerations
- A small apartment may not be the best destination for it, as it is a large speaker.
- Only a single pair of binding posts is included, so bi-amping or bi-wiring isn't an option.
- It may not be suited to very small rooms where the bottom end can be overpowering, and positioning is important to get the most out of the speaker.
Comparisons (according to reviewers)
- Vs. Focal Sopra N°2: It betters it in terms of scale, presence, dynamics, and detail, resulting in a bolder presentation, greater subtlety, separation, texture, and brings more individual character to voices and instruments, a function of its far more sophisticated harmonic development.
- Vs. Wilson Audio's Sasha W/P: The Focal Sopra N°3 is a more enjoyable speaker to listen to and costs less; the Sopras are lush and wonderfully pleasant to listen to, as opposed to the Wilsons, which are more analytical and difficult to tune in properly.
- Vs. Focal Utopia Scala V2: The Sopra N°3 is a price and performance stepping-stone to the Utopia line.
- Vs. Bowers & Wilkins 800 D3 speakers: Bowers & Wilkins speakers can often be a bit laid back and polite, making the Sopra N°3 a different alternative.
Takeaway: The Focal Sopra N°3 is a high-performing speaker that is able to play any type of music with subtle sounds and unbridled force. It brings the listener closer to the music, so they can feel all the energy of a live performance.
