Experience Big Sound. From A Small Speaker.

Ultra-Low Distortion PURIFI USHINDI woofers

Top-tier 4” PURIFI USHINDI woofer engineered with advanced technology for ultra-low distortion and maximum dynamics.

Dual PURIFI USHINDI Passive Radiators

2 x 4” PURIFI USHINDI passive radiators deliver deep bass in a compact cabinet, eliminating port noise for clearer, more refined sound quality.

High-End AMT Tweeter

Powerful and fully symmetrical AMT tweeter for great dynamics, headroom, and highly accurate detail reproduction.

Superior Distortion-free Crossover

Crafted from premium materials, meticulously selected through data and listening tests to deliver exceptional performance and true value.

Aluminum Front Baffle

12 mm CNC-machined aluminum front baffle bonded to 12 mm MDF reduces cabinet vibrations and distortion.

High-quality Cabinet with Basotect®

15 mm MDF cabinet with horizontal bracing and Basotect® foam reduces distortion and absorbs backward sound.

Rewriting the Rules

Sharing much of the advanced technology found in the 6.2 model, the Clarity 4.2 speakers are engineered to deliver an astonishingly low level of distortion, setting a new benchmark for precision and fidelity in their class. The clarity and power delivered by a speaker this compact is nothing short of extraordinary. It’s a performance you simply have to hear to believe.

Clarity 4.2 is fitted with a custom-designed, fully symmetrical AMT tweeter, crafted to reveal even the most delicate nuances with breathtaking clarity. Clarity 4.2 also features 4” PURIFI USHINDI woofers, a breakthrough in ultra-low distortion design that brings remarkable detail and precision. These state-of-the-art drivers are not only pivotal in maintaining clarity, but also deliver bass that reaches astonishing depths, down to 40 Hz. For speakers of this size, such low-end performance is virtually unheard of.

Despite its ultra-compact size, Clarity 4.2 delivers an expansive, full-bodied, and deeply immersive presentation. The ultra-low distortion design ensures that what you hear is nothing but the music itself—pure and uncorrupted. Clarity 4.2 isn’t just a compact speaker. It’s a bold redefinition of what high-end hi-fi can be. While its sensitivity may be modest on paper, the Clarity 4.2 delivers ample output for rich, room-filling sound—as long as you give it the power it deserves. For those who like to listen at higher volumes or in larger spaces, adding a subwoofer or stepping up to the Clarity 6.2 is an ideal path forward.

High-end listening and everyday convenience

Clarity 4.2 brings refined audio performance into everyday living. Its compact form integrates effortlessly into any space, delivering a rich, detailed sound far bigger than its size suggests. Thanks to its wide, natural dispersion and meticulously engineered linear response, the sound remains beautifully consistent and balanced throughout the room, perfect for relaxed sessions with family or friends. And when it’s time to lean in and enjoy a more expressive listening moment, Clarity 4.2 responds with finesse. Deep bass, delicate highs, and low distortion come together in a speaker that makes every musical moment sound extraordinary.

What also sets the Clarity 4.2 apart is the mix of exceptional performance, uncompromising design, and true long-term value. While firmly positioned in the high-end category, it offers a level of engineering, component quality, and sonic precision rarely found at this price point. It’s designed not just to impress today, but to deliver lasting satisfaction for years to come.

A long-awaited alliance

Radiant Acoustics was born from a powerful collaboration to make high-end hi-fi accessible to all music lovers. Founded by Peter Lyngdorf, it brings together three of his esteemed companies: HiFi Klubben, PURIFI, and Nordic Hi-Fi, combining over 80 years of expertise. This partnership unites PURIFI's cutting-edge technology, HiFi Klubben’s industry knowledge and infrastructure, and Nordic Hi-Fi's direct-to-consumer model to create top-tier audio products at a reasonable price, unlike anything you’ve seen before. The result is the Clarity series, a speaker that redefines premium sound, making superior hi-fi without the hefty price tag.

Setting out on the journey to create such an exceptional product is no easy task. Every component of the Clarity speakers is crucial to their pristine performance, and we are committed to ensuring each one meets our rigorous standards. We take immense pride in the fact that every Clarity unit is made in Denmark by some of the world's most qualified professionals. Before shipping, each speaker undergoes meticulous testing with state-of-the-art computer and audio equipment, ensuring they achieve the precise quality and performance we demand.

Customer Reviews

Overall rating: 4.9 / 5 from 23 reviews.

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

Incredible sound from such a small speaker!

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!

Clarity 4.2

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

Clarity 4.2

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!

Clarity 4.2

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.

Clarity 4.2

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.

Clarity 4.2

Very detailed and natural sound with deep bass for such small speakers. Great for classical music and jazz.

Customer photo review of Clarity 4.2

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.

Customer photo review of Clarity 4.2

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.

Clarity 4.2

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

Clarity 4.2

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.

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.

[..] 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. [..]

GO TO REVIEW

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.

GO TO REVIEW

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.

GO TO REVIEW

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.

GO TO REVIEW

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 sets a new standard for what you can expect in terms of weight and bass from such a small speaker.

GO TO REVIEW

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.

GO TO REVIEW

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!

GO TO REVIEW

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.

GO TO REVIEW

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.

GO TO REVIEW

The combination of PURIFI technology, the AMT tweeter developed by DALI, and Peter Lyngdorf’s vision results in a product that manages to combine an extremely transparent sound with surprisingly deep bass, while maintaining low distortion even when subjected to high sound pressure levels. [...]
Clarity 4.2 stands out as one of the strongest contenders for the title of reference among compact high-fidelity speakers of their generation.

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.

GO TO REVIEW

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. And you're just watching all these things come into existence from nowhere.

GO TO REVIEW

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.

GO TO REVIEW

[...] possibly the most capable tiny speaker to ever come through this door. If you're looking for the best sound from as small of a footprint as possible, then this is definitely a model to check out.

MEASUREMENTS

The Clarity speakers were measured at a height of 3.7 m above the floor in a large hall using PURIFI’s proprietary measurement setup. A calibrated GRAS 46AC microphone was used.

CLARITY 4.2 SPL & IMPEDANCE

The free field measurement at 2.5 m distance and near-field as well as mic-in-the-box measurements were post-processed to a synthesized anechoic SPL response with high resolution down to below 20Hz.

CLARITY 4.2 HORIZONTAL POLAR RESPONSE

The horizontal polar response at the tweeter height was recorded in 10-degree steps. The plot shows the response normalized to the Listening Window (i.e. average over 0-30 deg).
