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
This system combines the PMC6-2's unrivalled clarity and resolution with an active sub to form a perfectly integrated full-range monitoring system that is ideal for all high-end music production. In the case of the PMC6-2, configuring it as an XBD system reinforces the bass output of the main speaker's LF drivers, greatly increasing headroom and extending the bass down to 25Hz, creating a system with a sense of effortless capability.
Configuring the PMC6-2 XBD system is simple; connect the input directly to the PMC6-2, and add an AES3 digital cable to carry the main monitor's 'through' output down to the PMC8-2 SUB. The two cabinets can be connected either to a LAN or directly to each other via their network ports. When you select the dedicated 'XBD' mode the DSP seamlessly combines both units into a single, larger-scale monitor.
Further detailed configuration can be carried out from the rear-panel controls or using the intuitive SoundAlign™ browser-based software via the LAN connection, where both speakers appear as a single PMC6-2 XBD unit when linked. "3-way active, twin cabinet, mid-field reference monitor with ATL™ bass loading Frequency response: 25Hz - 25kHz (- 3dB @1m full space, on-axis) State-of-the-art Class-D amplifiers: HF 400W, MF 400W, LF 2x 400W, SUB(XBD) 2 x 400W Analogue / AES3 digital input (16/24-bit, 18 -192kHz sample rate) Digital 'through' output (AES3 24-bit 96kHz) SoundAlign™ network control interface for single or group EQ & settings Sophisticated DSP crossover, driver protection, EQ, and delay/polarity options Optional dedicated 19" floor stands"""

Our take on the brand
Our Summary
Product Strengths
- Wide soundstage with evident front-to-back depth
- Clear and detailed midrange response with good separation of instruments such as guitars and pianos
- Balanced low-end response allowing for clearer definitions in bass notes
- Precise time alignment contributes to accuracy, focus, and a uniform dispersion pattern
- Detailed and airy top-end combined with a reach-out-and-touch-it three-dimensional width and imaging in the midrange
Product Considerations
- Not an inexpensive monitor
- At 41kg, it is also very heavy
- At the large end of the nearfield monitoring spectrum—it's a midfield, really
- Lacks DSP (Digital Signal Processing) found in many modern monitors, relying on traditional electro-acoustic design
Comparisons (according to reviewers)
- Vs ATC SCM25A: Maintains a more balanced low-end response, while ATC SCM25A exhibited a slight bump in the lower mids
Takeaway: The Amphion One25A is an accurate and revealing mix tool with a perfect tonal balance, making it a good investment for professional use. Its low-end provides an utterly secure foundation for everything above, and it retains its dimension and punch at normal, moderate listening levels.
Video review

Product Strengths
- Unparalleled clarity, definition, and utmost accuracy
- Excellent bass extension and clarity, as well as proper tonal balance at every volume
- Super wide dispersion, and thus a bigger sweet spot
Product Considerations
- It would be overkill in smaller rooms
- A pair is a significant investment, so it makes sense that it's geared toward large, professional recording environments
- They weigh nearly 100 pounds apiece
