Radiant Acoustics, a rising star in the high-end audio world, has claimed the prestigious EISA Award for Best Bookshelf Loudspeakers 2025-2026 with its compact yet powerful Clarity 4.2. The Expert Imaging and Sound Association (EISA), comprising 54 specialist magazines and websites across 27 countries, lauded the Clarity 4.2 for its remarkable fusion of cutting-edge engineering and exceptional audio performance, setting a new benchmark in the bookshelf speaker category.
Innovative vision of Nordic HiFi
The Clarity 4.2, a smaller sibling to the acclaimed Clarity 6.2, embodies the innovative vision of Peter Lyngdorf’s Nordic HiFi, leveraging technology from Purifi Audio and a custom-designed AMT tweeter crafted in Denmark. Despite its petite dimensions—small enough to fit in the palm of a hand—the Clarity 4.2 delivers a soundstage that rivals speakers twice its size. It features a 4-inch Purifi USHINDI woofer for ultra-low distortion and dynamic midrange, paired with two side-firing 4-inch Purifi USHINDI passive radiators that extend bass response down to an impressive 40 Hz. The custom AMT tweeter, mounted without a waveguide, ensures crisp, detailed highs with exceptional clarity and warmth.
Astonishing performance
EISA judges highlighted the Clarity 4.2’s “astonishing performance,” noting its “deep, rich bass, excellent imaging, and detail” that belie its compact form. The speaker’s 15mm MDF cabinet, reinforced with a 12mm CNC-machined aluminum front baffle and Basotect foam damping, minimizes vibrations and distortion, delivering a pure, immersive listening experience. Available in three premium finishes—black matte lacquer, white matte lacquer, or walnut veneer—the Clarity 4.2 combines sleek aesthetics with robust build quality, making it a stylish addition to any space.
Democratize premium audio
Priced at approximately €2,598 per pair, the Clarity 4.2 offers high-end performance at a relatively accessible price point, reflecting Radiant Acoustics’ mission to democratize premium audio. The speaker’s dual balanced passive radiator design eliminates port noise, providing clean, controlled bass ideal for small to medium-sized rooms or desktop setups. Reviewers have praised its ability to extract fine details from recordings without sacrificing musicality, with publications like HIFICLUBE describing it as “a rare example of a small speaker with a surprisingly big personality” [].
Backed by Peter Lyngdorf’s decades of expertise and the collaborative efforts of HiFi Klubben, Purifi, and Nordic Hi-Fi, the Clarity 4.2 redefines expectations for compact hi-fi. Its EISA Award win underscores its dominance in the ultra-compact segment, offering audiophiles a speaker that delivers expansive, distortion-free sound in a footprint that seamlessly integrates into modern living spaces.
