The Anniversary 10 (A10) is a culmination of all the experience that we have gathered over the last 10 years of designing and building HiFi speakers. Over the last decade, we have produced and sold thousands of speakers to happy HiFi enthusiasts from all around the world. Listening to feedback from our customers, learning from the best and adding our own flavor to the mix, has created extremely popular and critically acclaimed speakers, and now, this has evolved into our best sounding speaker yet. The A10 is something we are truly proud of, both in terms of sound, look and production values. It is a true celebration of our passion for amazing high-end sound, great engineering and high value products.
Product Strengths
- Exceptional bass performance for its compact size, with bass that is fast, clear, and tight
- Multiple 'Master Tunings' offer customizable sound profiles, adapting to different room acoustics and user preferences
- A high-quality Purifi woofer and SB Acoustics tweeter contribute to clarity, detail, and low distortion
- A solid wood cabinet made in Denmark provides a luxurious look and feel
Product Considerations
- Bass output may diminish or be limited at high volumes to protect the drivers from damage
- A separate purchase of the Platin Stereo Hub may be required for full wireless functionality and room correction
- The 'Made in China' label applies to the electronics inside the cabinet
- While the A10 offers impressive bass, some may still prefer to add a subwoofer for a true full-range experience
Comparisons (according to reviewers)
- Vs Buchardt S400 Mark II, the A10 is more transparent with greater inner detail, clarity, and top-end extension—and deeper, tighter bass—while the S400 Mark II is more relaxed and forgiving with harsh recordings
- Vs Buchardt A500, the A10 has comparable performance, with possibly a crisper sound in some instances
Takeaway: The Buchardt Anniversary 10 is a compact yet powerful speaker that offers a customizable listening experience. Its impressive bass and versatile tuning options make it a great choice for those seeking a high-quality audio solution in a small to medium-sized room.

Our take on the brand
Product Strengths
- Delivers greater tightness and precision from the crossover point on down
- Delivers an extended high-frequency range, with greater detail and more openness without harshness
- Stereo imaging is amongst the best
- Has no sweet 'spot', which allows the engineer, producer, and client a fairly similar listening experience
- Has a smoothly extended bass response that reveals what is really going on in that elusive bottom octave
Product Considerations
- The BM-15As may be overkill for a smaller mixing environment and better suited for larger rooms
- High end is as clean and accurate as the BM-12s, but the mids were a little lacking
- While they have a slightly forward characteristic, it doesn't get in the way of accurate monitoring
Comparisons (according to reviewers)
- Vs Dynaudio BM-12 MK3s—BM-15A has more bass extension and pure raw SPL power
- Vs Dynaudio BM-12 MK3s—BM-12 MK3s have more detail in the mid-range
- Vs Dynaudio BM-12 MK3s—BM-15A are far louder and put out substantially larger amount of energy in the bass and subs
- Vs Genelec, Focal, Neumann, and Event—the Dynaudio BM series are in the same class as these monitors
Takeaway: The BM15A is a speaker that gives great stereo imaging with a wide frequency range, and produces an accurate sound which is nice to listen to for long periods. Full-range monitoring in a smaller studio is possible with these speakers.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Detailed and powerful low-end response
- Articulate midrange driver
- Crisp and airy high-end without harshness
- The built-in EQ and Sonarworks SoundID Reference integration allows users to tailor the sound to their specific room acoustics
- Wide, deep, highly detailed, and solidly centered soundfield
Product Considerations
- Self-noise/hiss can be noticeable up close
- To fully use the Sonarworks feature after the trial, users would need to purchase the software
- Some users experienced initial connection hiccups with the A Control app
Comparisons (according to reviewers)
- The A8H offered a better value than the Dynaudio LYD 48 due to sound, build quality, and features like the built-in EQ
- The A8H offers more DSP capabilities, and is less expensive than the HEDD Audio Type 20 MK2 or Neumann KH310
- It is halfway between the less expensive but less sophisticated Dynaudio LYD 48 and ADAM Audio's own S2V—which, although a 2 way, offers step up in terms of sophistication
Takeaway: The A8H studio monitors deliver exceptional sound quality with user-friendly features—enhancing the overall audio production experience. These monitors, with versatile connectivity, DSP-driven room adaptation, and impressive audio performance, are a great choice for those serious about audio.

Our take on the brand
Our Summary
Product Strengths
- Excellent balanced delivery with precise midrange
- Well-specified, easy-to-use EQ and room correction settings
- Good low-frequency extension given its compact size
- Produces a beautifully clean and well-defined sound, with no harshness in the highs and a real sense of spatial depth and stereo width
- As mixing tools, they tell it like it is, so good mixes sound 'right' and flaws are shown up clearly, just as they should
Product Considerations
- Expensive
- There's no straightforward way to hook up the Core 5s to the Core Sub Compact if all connections are to remain analogue
Takeaway: The Core 5 is a compact, accurate, and high-quality studio monitor that delivers a balanced and detailed sound perfect for smaller studios or immersive setups. It is comfortable to work with for extended periods, making it a great choice for professional use.
