I'm not inclined to write reviews of things I buy. If I pay a fair price and get the expected, advertised, result, that seems normal and sufficient. I don't think it requires extra communication and exaggerated kudos. However, my satisfaction with the Clarity 4.2s exceeds the normal expectation. They replaced Marten Duke IIs I got from Marten in exchange for performing and recording some music for them a few years ago in Gothenburg. The Martens are good. In my case, in a near field desktop setup, the Clarity's are noticeably better. The bass is deeper and clearer, and the soundstage significantly larger. I'm 90, and my ears are compromised. Nevertheless, this is an immediately noticeable improvement. More spacious and detailed sound, better bass, no shortcomings I'm able to notice, and all in a smaller package. Thanks, Chuck

SOUNDSTAGE! HI-FI
It is indeed a high-end speaker without a high-end price, one capable of creating wonderful musical experiences, proving once again that great things really can come in small packages
LITE MAGAZIN
They really do sound as good, if not better, than many full-size floorstanding speakers in their price range - but they take up very little space.
HEADFONIA
The Clarity 6.2 is the defining speaker to beat in its category and has very quickly become one of my favorite bookshelf speakers available.
LB TECH REVIEWS / LYD & BILLEDE
It's rare to find a speaker so free from colouration and distortion. Deep bass in a mini cabinet. They're not inexpensive, but they sound like more.
HIFITEST.DE
The Clarity 6.2 is a stroke of luck from a loudspeaker in which outstanding chassis technology and a clean tuning lead to a really great result.
STEREO+
[...] the music that comes out of these speakers has characteristics that
can replace more expensive speakers in many areas.
HIFI-JOURNAL
The performance [...] can be described as excellent with a slight tendency towards "outstanding". The audiophile approach and the performance on offer exceed much in this (price) segment.
BEST OF HIGH END
The Clarity 6.2 is a true statement of what is technically possible and achievable in terms of sound reproduction today. I’m not joking when I say that this kind of performance easily requires double or triple the budget. Bestofhighend Award!
HIFI.NL
Their first speaker guarantees that. The Clarity 6.2 is a perfect example of what happens when you apply the latest innovations with a lot of know-how AND know what you want in terms of sound.
FWD.NL
The fusion of the triple PURIFI USHINDI woofers with a cleverly implemented AMT tweeter and the extremely quiet cabinet yields a clean-playing speaker with impressive low-end power.

Overall, I really like this speaker. [...] This speaker is class-leading in dynamic range and offers a nice tapered in-room response, making it one of the best-performing speakers in its class.
STJERNHOLM REVIEWS
The sound is so very Lyngdorf—you get a very neutral and correct and precise and powerful dynamic presentation that doesn’t try to add or really subtract anything from your music.
ANDREW ROBINSON
The Clarity 6.2 by Radiant Acoustics is a solid speaker in more ways than one. When powered correctly and given the room to breathe, they are impressive, but they’re also a touch finicky. This type of speaker will be great for die-hard audiophiles.
ABX Audiophiles
The Clarity 6.2 is praised for its ultra-robust build, rich yet precise sound, and ability to scale with power. It stands out in a saturated market and is recommended as a top-five consideration for bookshelf/stand-mount speakers.
NEMO PROPAGANDA
Imagining: crazy, top-notch. Soundstage: really, really big. Speakers are trying to show you that midrange region, the singer is locked in, and bass is very powerful and very effortless with really good extension, but no midrange bump or boost. That’s what it sounds like.
NEW RECORD DAY
For those who like to go fast and are interested in hearing all the details that are missed in the recordings and love a front row experience when rocking out, the choice is clear and the 6.2s are one heck of a speaker to beat in that particular category.
MAD AUDIO
It's really hard to find a weakness in the Clarity 6.2 [...] every track, every music genre sounds fantastic, reminding me when I was a kid playing with my uncle's hi-fi stereo [...] suddenly everything just came alive.

[..] You might be able to hold this speaker in your hand – although the build quality and mass of its cabinets, with aluminium baffles, will surprise – but it sounds like a model twice the size. Utilising three 100mm USHINDI woofers from Purifi, two employed as side-firing passive radiators, and an AMT high-frequency driver mounted in a waveguide, the Clarity 4.2 combines a deep, rich bass performance with excellent imaging and detail.

STEREOPHILE
The system including the Radiants played with extreme transparency, foot-pounding vigor, tonal neutrality, and big-screen mojo. What more could anyone ask from tiny, $2998/pair loudspeakers? [...] With a more-than-fair all-inclusive price and near state-of-the-art sound quality, the Radiant Acoustics Clarity 4.2s might be the biggest bargain since nickel Cokes.
HI-FI NEWS
Far from minuscule when it comes to sonics, the Clarity 4.2s are small speakers that wed solid stereo imaging and insightful detail with eye-opening bass, effortlessly challenging some floorstanders. Take care with positioning, and partner with a beefy amp, and this miniature will fill the room with a glorious sound. It’s a great little speaker – and a persuasive demonstration of Purifi’s driver technology.

The Clarity 4.2 is an all-round successful loudspeaker that delivers a great music experience through the combination of outstanding chassis technology, extremely clean tuning, and a convincing cabinet concept.
STEREO+
Radiant Acoustics Clarity 4.2 plays very well compared to everything else, and fantastic if we judge them by their size. It is, of course, the surprisingly generous bass reproduction, but in everyday use, it's the clean, open and dynamic midrange that attracts most of the attention [...] Clarity 4.2 [...] in many ways and in many ways sets a new standard for what you can expect in terms of weight and bass from such a small speaker.
LYD & BILLEDE
Radiant Acoustics Clarity 4.2 is a loudspeaker that stands out from the crowd. The sound is just as uncompromising as the design. Although Peter Lyngdorf would probably say that one has simply chosen the best compromises. In any case, extreme engineering choices have been made.
HIFI-JOURNAL
A more compact speaker that shares the same DNA as the larger debut model, it delivers an outstanding overall result. Comparing the two models wouldn’t be fair, as the 4.2 is clearly aimed at competition in the ultra-compact segment. In that space, one could almost say it's extremely dominant and faces little real competition, thanks to its impressive performance capabilities. [...] A clear purchase recommendation!
HIFICLUBE
The Radiant Acoustics Clarity 4.2 is a rare example of a small speaker with a surprisingly big personality. Its enclosure blends advanced engineering with an ear for musicality, pulling tiny details out of recordings without sacrificing warmth or emotion. They also embody a classic hi‑fi principle: don’t listen to the speaker; listen to the music. The soundstage feels larger and more vivid than I ever expected from such a small box.
FWD.NL
Everything has been preserved to create a speaker that delivers tight bass and focuses on purity. Its previously neutral sound will entice you over time, and it will win you over. Pair the Clarity 4.2 with a good amplifier, and you’ll be rewarded with sound reproduction that is both controlled and relaxing to listen to. A beautiful combination.

The result is speakers that have stupendous bass extension for their size. They also have exemplary high-frequency performance, helping to produce a massive soundstage with some of the best stereo imagery I’ve heard. […] The Clarity 4.2s are ideal in small to medium-sized rooms. For those looking for a high-performance speaker, diminutive in size but not in sonic nature.

Their ability to just have such an inky, black background. It is so silent. It is as if the details that are suspended in the soundstage are just literally appearing from the ether of the universe and just suspending themselves all around you.

The Radiant Acoustic Clarity 4.2 is a breakthrough compact speaker that defies expectations by delivering tower-like bass power, a large soundstage, and refined tonal balance in a small package. It needs a capable amplifier and has some volume limits with bass-heavy music, but performs excellently in most setups without a subwoofer.

CLARITY 66 REVIEWS

EISA
The floorstanding Clarity 66 builds on the success of the EISA Award-winning Clarity 6.2 and 4.2 bookshelf speakers, taking the concept to a new level. With increased input from sister brand Purifi Audio and renowned designer Lars Risbo, the Clarity 66 uses an ingenious Superflare bass port and the latest 165mm (6.5″) Purifi Audio USHINDI woofers to achieve impressive low-frequency extension with low distortion. Add in a custom air motion transformer (AMT) tweeter mounted into a waveguide and operating with the woofers in a two-way configuration, and you get superb, precise sound across a wide frequency range. The Clarity 66 is beautifully built, available in three finishes, and a triumph of engineering that will delight even the most critical listeners.
LB TECH REVIEWS / LYD & BILLEDE
Radiant Acoustics Clarity 66 is an uncompromising show of force in Danish engineering. It delivers a massive, distortion-free soundstage with an authority that usually costs twice as much. If you’re looking for a speaker that flatters the music, you should keep looking. The Clarity 66 serves the truth raw and unvarnished. It demands a capable amplifier and room correction to keep it in check, but if you have that under control, you get a genuine high-end experience at a price that can only be called a bargain in this class.
FWD.NL
The Clarity 66s contain a great deal of groundbreaking audio technology. The same could be said of the Clarity 6.2 and 4.2; in that sense, this floorstanding speaker from Radiant Acoustics is 'simply' more of the same. However, some nuance is required. Many components are the same, but crucial parts are different. And, of course, it is also a larger cabinet. The end result is a loudspeaker that, provided it has the right amplification, sounds so effortless that you will turn it up almost without thinking. It is a brilliant next step in the Radiant story, a beautiful synthesis of everything Lyngdorf stands for.
HIFI.NL
The Clarity 66 is a technically impressive speaker. It’s also a prime example of how the clever combination of advanced technologies results in a floorstanding speaker that delivers equally impressive sound quality. For existing Radiant fans looking for something “more” than the smaller Clarity models, it delivers a fuller experience that goes beyond “the little ones plus a bit of extra bass.” The cohesion and control of this impressively crafted Clarity 66 are excellent, allowing the music to fill the room with a sense of calm and spaciousness.
STEREO+
The Clarity 66 is one of the speakers we’ve heard in this class that interferes the least with the music. It plays everything with the same relaxed precision and rhythmic clarity, and has a balance that makes it very easy to relate to across all types of music. It reproduces everything with the same relaxed precision and rhythmic clarity, clearly demonstrating why it belongs among the market’s most interesting and exciting floor-standing speakers in this price range. If you need to adapt your system to a slightly smaller room, the Clarity 6.2 and the tiny 4.2 are good alternatives if you want some of the same sound quality but can’t quite find room for them in your living room
SZTEREOMAGAZIN
The Radiant Acoustics Clarity 66 delivers a massive, distortion-free soundstage with a level of confidence usually found only at double the price. If you are looking for a speaker that caresses the music with delicate refinement, this is not the one for you; the Clarity 66 serves up raw, unadulterated reality. It requires a suitable amplifier and room correction to tame it, but once that is achieved, the owner is rewarded with a true high-end experience.

From the very first listen it was clear that something entirely different had arrived.
This is not just a scaled-up version of a Clarity 6.2. It’s something totally different, done in a highly controversial way - and it rewrites what is possible in speaker design! The result is a speaker, that delivers deep, clean bass and exceptional midrange clarity from the same drivers — without the usual compromises.
ERIN'S AUDIO CORNER
[...] I spent around three and a half hours just straight up listening to music. I got back to the joy of enjoying speakers, and I went through an entire library of music, and I wound up actually even making an Erin's '80s playlist [...] Clarity 66 is a badass speaker that I would be happy to own.

Overall rating: 4.8 / 5 from 71 reviews.
My Clarity 66s replace a pair of Quad 22L2s that I’ve loved for years. My room is 3m by 4m and I was worried that wouldn’t be enough space to let the 66s do their thing. With near zero effort on set up or placement (about 20cm from the back wall and right in the corner) my room is now a cathedral. Or a nightclub. Or a stadium. The first comment out of everyone who’s heard them is about the clarity. The second is about the bass and fullness. I’m very, very pleased. These were a big purchase for me, but I can see and hear where the money went. The improvement in listening enjoyment is priceless.
Incredible sound from such a small speaker!
Exceptional speakers, unbeatable value for money, unbeatable performance, defined sound, incredible bass for the size, absolutely worth trying!
This is the second speaker I buy from Radiant Acoustics. When I listened to clarity 66 at Axpona 2026 I was amazed of the sound. First of all speakers are beautiful, the oak veneer paired with the aluminum front and the 2 Purifi drivers looks super nice, the cherry on the cake is the amt tweeter. I love the look! The sound is … well as the brand explain, honestly I don’t have anything to add I just confirm the speakers sound amazing! What I really liked is that they sound very nice at any volume. I’m not a reviewer i just love music! Very powerful, lots of clarity and the image is something I just discovered when I close my eyes and can picture the artists playing for me, just wow! I would recommend this product to anyone hands down, as well as the 4.2 I love them as well! Saludos desde México amigos
Gorgeous speakers!!
The speakers and the stands are exactly what I was hoping for - small but mighty.
I discover this brand at Axpona 2026, talked to Friedrik which took care of me nicely and despite the show was over He did have time to show me the speaker and event connect it again so I could experience it. At first when I saw and listened that beauty I tought wow! 2 months later after the show and after watching many reviews in YouTube and exchanging messages thru IG with Radiant; I decided to buy this 4.2 in white! This is to me a very nice showcase of what a danish design is, is amazingly beautiful, can’t stop watching and touching it hahaha. I have been listening to them for 2 weeks now and day by day I love it more and more!! My room is about 4X4.5 meters and they are perfect!! The bass is amazing, mid and highs as well I’m not a sound reviewer at all I just love music and love to listen to it the better possible way. But have little knowledge about sound. Now that I now the quality of the 4.2 I’m start thinking to buy the big ones, Clarity 66! I just need to know where I’m going to place them. Those things surely are gonna be amazing!! In few words: very satisfied, very happy! Loved them and would (and will) buy more of Radiant products! Also the communication with Radiant team is very good they always reply my questions or comments and I really appreaciate that! Saludos desde Guadalajara!
The speakers are everything that they were described to be. Once set up and positioned as recommended they freakin disappear. They are positioned just over a meter from the front wall ( back of speaker) and a meter from the side walls with 2.2 meters between. The tonal balance is spot on. The highs, mids, and bass are exceptional, as is the build quality. They are an absolute bargain. Congratulations to all involved in the design, engineering and construction. Greg Bauch
These speakers are Unreal! I’ve been listening to music I have listened to for 50 years and I hear things I’ve never heard. The clarity is unexplainable, you have to hear it to understand. I look forward to many years of immersive listening. Thank you for making such a quality product.
These speakers are amazing, I use them in my office replaced LS50s. The soundstage, bass articulation, imaging and separation are far superior and midrange and vocals are superb. They are better than the LS50s... Which I love... But these are without a doubt better..much better. Delivery and dispatch were entirely uneventful to Australia. Highest recommendation
Got the speaker for a week plus. Found that the bass is Deep and authoritative. Midrange where voices sound natural and clean. Good low volumes too.
It sounds good, it didn’t give me that ‘whoa’ that sound fantastic at the first listen. I wish it came with speaker grills, the twitter has this thin film like screen that may easily rip if touched. So far so good!
I have paired the Clarity 6.2s with the NAD M33 V2. Awesome combo and the speakers are INCREDIBLE 💥💥💥
I had a pair of Klipsch RP-8000F II towers. The Clarity 6.2s make those sound like children's toys. It is amazing how much clear, crisp, detailed, and pure sound comes out of these speakers. The sound stage wraps around like surround speakers. Instead of a sweet spot where it sounds pretty good, these open the sound stage and give it bowling alley depth where I can clearly hear each instrument. The distortion in symphonic tracks is gone. Muddy bass is gone. I can hear details in tracks that I never noticed before. I highly recommend a pair of these. These are paired with dual Rhythmik Audio A370XLR2 F12s crossed over at 80hz to extend the range to 20hz. The speakers are behind a Purifi Audio 1ET6525A Dual Mono Amplifier with Sparkos SS3602 OP Amps. No EQ required.
Considering the craftsmanship, compactness, made-in-Denmark-ness, and of course the performance, I feel like this is not only a great pair of speakers, but also very fairly priced. I’m using them in a smallish (130sq ft) room, almost near-field, with a 70w of class A amplification, and I am getting such a balanced sound. Surprisingly deep and clear bass. I’ll probably add a sub, but for now it is still very satisfying, and amazing for such a small speaker. Clear highs, not exaggerated or harsh. Natural vocals timbre. I also have a pair of Harbeth bookshelves that I use in a similar space. Compared to the Harbeths, which seem very focused on mids, the Clarity 4.2 do not have a ‘voice’ that is easy to describe— instead it’s a very well-rounded and well integrated sound, with both warmth, fullness, and clarity.
I love these loudspeakers. They perform exceptionally well with my 40W/channel NAD C 328. I find them accurate but not sterile, and they are quite revealing of the source material. I have not noticed any distortion. Since they arrived I've spent hours rediscovering my favorite tracks, and exploring new ones. Now and then I'll notice something the speakers are doing great, for example clarity on the flute section, or low octave fundamentals on a string bass. But mostly I'm just into the music, which is the experience I seek. The soundstage is quite stable. Width, height and depth vary with each recording. I like to sit at the sweet spot, which is narrow with the Clarity 4.2s, but the listening experience is very good wherever one sits or stands in my 24' x 16' LR, with cathedral ceiling, and is also good in adjacent rooms. In my room, most tracks benefit from a little EQ, mainly a boost at 2k to 4k to bring vocals forward. Your mileage may vary. I currently have them on the short wall. Because I sit about 13' from the speakers, I have them about 8' apart and 25" from the wall behind them to the rear of each enclosure. I plan to experiment more with positioning, although I'm somewhat constrained by the floor plan and furniture. A word about appearance: these are so small, and the stands so unobtrusive, that they practically disappear in my room. The small size was one reason for choosing them. My wife approves, and also is happy with how they sound.
These are beautifully designed and fabricated. Easy to assemble, very solid yet not obtrusive. My wife, who is particular about appearances, has never commented on them!
Fantastic experience with the speakers so far. Amazing dynamics and presentation of music. They are versatile in placement in my apartment.
I was very impressed at how well integrated the stands are with the speakers as a well thought out system. I would recommend the are a mandatory purchase with the speakers.
Very detailed and natural sound with deep bass for such small speakers. Great for classical music and jazz.
The sound is excellent. The highs are accurate and not hard to listen to. The mids are accurate with excellent definition and separation of sources. The lows are also surprisingly good although I may couple with a sub for organ music etc. A couple more points: First the amplifier is a Hypex Nilai500 and I can't imagine driving the speakers with less wattage. That said I still haven't turned up the volume to the point where I think the sound will be most realistic. Last, I disagree that the speakers do not need breaking in. Although they loosened up over 24 hours when I first set them up they seemed mildly restricted. Whether that was from the long flight or what I don't know but there was definitely a difference over the first several days.
Speaker stands are attractive and really solid. With the feet adjusted and on the pads correctly, the speaker has no vibration and does not move without a significant push.
I'm not an audio expert. I just like music. I listen to everything and these speakers seem to sounds good with everything. I live in a small apartment. I can't turn my stereo up very loud because neighbors. Maybe 65db if I'm lucky. I don't need big speakers but was never able to find small speakers that I was satisfied with in the bass department. My stereo setup is stuffed in a corner next to a big window, which has always posed sound challenges. These Clarity 4.2s have been getting great reviews so I decided to try them. It is crazy how good these sound playing through my Lyngdorf TDAI-3400. Reviews of these talk about how good the bass is and how little distortion they have. To my ears, this is all true. It's kind of bonkers how powerful low bass can sound from these tiny boxes while still remaining crystal clear. It's some kind of magic. My wife hates how they look compared to the old speakers. I kind of agree with her. More colors would be nice, but they sound sooo goooood.
I recently purchased a pair of Clarity 4.2's at HiFi Klubben in The Netherlands. The speakers sound absolutely fantastic and produce a rich bass, regarding to their size. Unfortunately, the build quality is not as one may expect. My first pair had some glue residu on the edge of the side woofer/cabinet on one speaker. The underside of the other speaker wasn't fully flat, so it wobbled. On the new pair I received it is clearly visible that the rubber of the tweeter in the bottom right corner has not been cut straight, resulting in a notch between the tweeter and the speaker cabinet. Please see the attached photos. I don't think this level of finish is appropriate for a € 2,598 bookshelf speaker. According to my HiFi Klubben store these imperfections make the speakers 'unique', but sadly I am disappointed by the clear lack of sufficient quality control.
The depth and clarity is incredible, and the soundstage is precise and wide, especially considering the size. These speakers sound much larger than their size suggests
A
The Clarity 4.2 speakers have exceeded my expectations. I read and watched the video reviews and thought this would be a great change to my office system and it has been great. I plugged them into my main system which uses full-range towers/tube amps and the bass and imaging went up another notch. Wish I hadn't done that because now I am looking at my office system and wondering what I need to do to get closer to what I heard at home.
Provides incredible stability and support to the Clarity 6.2. As solid as Thor's hammer.
Every time I play a new type of music on my Clarity speakers, I tell myself that it's their favorite genre, but in fact, they play all genres beautifully: classical, pop, rock, jazz, blues... These are great speakers that you can listen to for hours without fatigue.
Incredible stereo imaging! It says a lot when the British Audiophile said the Clarity 4.2 was the best imaging speaker he has reviewed. Nemo Audio Project also did a great job of describing the speaker. In my room it provides enough bass to hold off on a sub purchase for the time being.
Please let me know the return procedure. I test them out for 2 weeks with various systems, unfortunately, they are not the sound that I am looking for. I would like to return them.
Hrají výborně. Vynikající prostor. Když jsem je poprvé zapojil, myslel jsem, že mám puštěné domácí kino. Vyžadují silnějsí zesilovač. Luboš, CZ
Mind-blowing, these speakers are in a league of their own.

Highly impressed with the Clarity 6.2s. They throw out a huge three dimensional soundstage, with great detail and dynamics throughout the frequency range. The way they can produce all the sounds and layers in the music with each one not interfering with, or being interfered with by, all the other sounds and layers that they are producing has to be heard to be truly appreciated.
Packaged, perfect ! Great finish and well made. Currently getting them dialed in for my listening position. So far so good, crisp clear and great stage presence. These will be on stage for quite some time replacing my KEF R3's that gave me a decade of service. Let the journey begin! Mighty Mouse Miami Beach, FL
Incredible performers for speakers of that size. I thought they would be good, but they have surpassed my expectations. Some next level engineering in these speakers to get this kind of performance. Well done!
