Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Avantgarde Acoustic distinguishes itself by using horn-loaded drivers across the frequency spectrum in many of their designs, prioritizing efficiency and dynamic range over traditional driver configurations.
- They offer a modular upgrade path with their speakers, allowing users to transition from passive crossovers and traditional amplification to fully active systems utilizing Avantgarde's proprietary iTRON current-drive technology.
- A core design principle is achieving seamless integration between drivers, particularly between the horn-loaded components and powered subwoofers, using DSP and careful design to create a cohesive soundstage.
- Avantgarde allows extensive aesthetic customization options, including a wide array of colors for the horns and finishes for the cabinets, enabling customers to tailor their speakers to suit individual tastes and room décor.

Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
Firstly: Most prominently, our spherical horn technology with its precisely calculated wave-launch accounts for a unique appearance, outstanding (typically 104+ dBs/W/m) efficiency, and a favorably controlled sound dispersion in any room and environment. This gives our speakers an objet d'art character and makes amplifier choice a straightforward task: it’s all about sound quality, not about wattage.
Secondly: With launching the G3 series speakers, the range is optionally available in fully active versions, with the horn section powered by a breakthrough innovation regarding the membranes' displacement control: the proprietary iTRON current-drive amplifier technology. Executed in single-ended push-pull, fully Class-A, and zero-feedback topology, iTRON is the ideal and logical choice for offering not just conveniently connectable powered speakers but to consequently provide a musical experience beyond what is possible with customary voltage amplifier technology.
What's your approach to customer support?
Our customer support consists of a network of stipulated regional service providers and a central coordinating office at the factory for prompting the most effective procedures. Standardly, our local instances will be the recommended and most effective support channel (e.g., because of a time zone offset to Germany), while in specific cases, e.g., with "vintage support," our own team of experienced specialists may of course be addressed for appropriate advice and servicing.
What are your favorite tracks for showcasing the strength of your products?
Showcasing the famous Allman Brothers Band in an astonishingly intimate frame, on stage in a rather small club (while filling stadiums, usually), is the track "In Memory Of Elizabeth Reed" from the record An Evening With The Allman Brothers Band – 2nd Set, recorded live in LA around 1992. Listened to by a dynamically capable and highly resolving speaker like from our range, the skillful, fun-driven playing, the vibrant atmosphere, and the cheering public make a "be there" experience par excellence. Ten minutes and fifteen seconds that fly.
Leopold Stokowski's famous Rhapsodies collection from 1960 (on Living Stereo, recorded at Manhattan Center) still holds surprises! While considered to be a "nice recording" anyway by many, especially true for the Liszt "Hungarian Rhapsody No.2," listeners who become exposed to the recording through our speakers realize far greater "ebb and flow" contrast in the orchestra's fantastic playing. At realistic concert level? As you please!
Meraki's "La Fong" track has driven people to tears (of joy…) where one would never think that this is the kind of music they'd fancy. Powerhouse electronic music that combines thrilling dynamics with a wonderful sense of space that does not merely scatter sounds into thin air but makes them glitter. A special, almost limitless trip when listened to by the right set of speakers.
What other products pair best with yours?
Especially in combination with our iTRON amplifiers, the co-branding question does not need an "exclusive" answer. Rather, it deserves an "inclusive" answer, as the high degree of control over the musical result ensured by horns and current-drive has generated feedback from our network that attests many excellent (no matter if praised for a specific strength or for an overall sound balance) source components to make a truly "shining" contribution.

Our take on the brand
Elegant and powerful, our BXT turns any pair of Kii THREE into unrivaled floor-standing speakers.
Our summary
Product Strengths
- When combined with the BXT module, the system delivers tight, dynamic, and nuanced bass reproduction
- The addition of the BXT allows the system to reveal subtle details in the lower frequencies that are typically missed
- The BXT system offers a balanced sound, with the midrange frequencies benefiting from the addition of the BXT module
- Are relieved of some bass duties, letting them focus more on the mids
- The combination with the BXT module creates a cardioid dispersion pattern, reducing reflections from side and rear walls—minimizing the influence of room acoustics
- Ease of use is another strength of the concept
Product Considerations
- Some perceive it as sounding 'too digital' or 'too analytical' on its own, lacking the warmth of other speakers, but the BXT module helps to address this
- The display on the Kii Control is considered small, making it difficult to read in poor lighting conditions
Comparisons (according to reviewers)
- Versus ATC speakers, ATC speakers have a warmer, more colorful sound
Takeaway: The system, especially when paired with the BXT module, delivers exceptional sound quality with deep, controlled bass and reduced room interaction. For those wanting a system with great clarity and power, this could be a good pick.
Video review
Our take on the brand
Product Strengths
- Astonishing control, detail, coherence, and extension due to 200 Watts being connected directly to the bass driver
- The new ATC tweeter is more revealing yet sweeter than the SEAS unit it replaces, making the speaker more charming without losing transparency
Product Considerations
- Installation potentially difficult, as it is a large and heavy speaker, weighing 75kg each
- Bass performance reveals flaws in recordings that are tweaked to sound good on most speakers

Our take on the brand
What competes at this price?
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.
Video review
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.
