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

Our take on the brand
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
- Dramatic, futuristic appearance with science-fiction-solidified, large wedges of carbon fiber that look like they are approaching warp speed while standing still
- Tight and quick bass due to the four smaller drivers working in concert
- Silky yet extended treble
- Image in the room was delightful in its solidity, with vivid imaging, giving equal weight to lateral staging and depth delineation
- Very good value for money when compared to their competitors
Product Considerations
- Finishes of the cabinets are limited to two colors (black and white)
- A run-in period is needed to get rid of the slight brittleness in the drivers when box-fresh
- A big loudspeaker, so ensure adequate space for them to breathe
- Backloading of bass may cause some positioning problems in some rooms
- One reviewer noted a fairly wide trough, centered at roughly 200Hz, that maxed out at nearly 10dB, so music that relies on this power region may not sound as good
Comparisons (according to reviewers)
- Vs Audiovector R6 Arrete´: The reviewer preferred the isobaric bass of the R6s, though the price difference certainly does make one sit up and take notice, and in every other way—in the reviewer's opinion—the Børresen X6s outperform the Audiovectors, though it's a fairly close run race
- Vs Børresen X3: The X6 offer a bigger 'feel' and digs a bit deeper in the bottom end than the X3
- Vs Bowers & Wilkins 801 D4 Signature: Crossover between the midranges and the tweeter rivaled the clarity of the Bowers & Wilkins 801 D4 Signature
Takeaway: The Børresen X6 speakers offer excellent value for the money and create a sense of scale uncommon in speakers at this price. With adequate space and solid amplification, these speakers offer a very attractive proposition.
Video review
Our take on the brand
Our Summary
Product Strengths
- Vast soundstage made the speakers sound much larger than their size, filling the front of the room with music and accurately scaled images
- Superb, recently redesigned 25mm beryllium tweeter delivers a polished sound in the mid to high frequencies and extends high-frequencies up to 60kHz
- Produces a powerful, tight, and pitch-specific bass, especially in the mid-bass
- Accurate and clear soundstage shows sound sources in well-defined places and the whole and the detail at the same time
Product Considerations
- The E2 sounds like small stand-mount monitors at first glance
- Bass is delivered in a rather economical way
- Solid and powerful amplification is needed for higher volume output due to a lowish sensitivity rating of 87dB/W/m
- Placement closer to the back wall and electronics such as a tube or saturated transistor amplifier can allow the speakers to show a different world in terms of tonality and spatial presentation
Comparisons (according to reviewers)
- Compared to BBC monitors, the TADs provide a much better-built body of instruments, better-marked sound layers, and a better insight into the recording
- Compared to Focal, TAD is softer than Focal when comparing tweeters
Takeaway: The TAD Evolution Two speakers are great-looking with a small footprint, providing an accurate and dynamic sound that doesn't embellish anything. The speakers are able to extract nuance and reveal more of the genius of the music, letting the listener dig deep and bask in all that the music has to offer.
