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.

Aluminium 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.

EISA BOOKSHELF LOUDSPEAKERS 2025-2026

[..] 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. [..]

READ AWARD CITATION

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

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!

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.

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.
