Arcam R25 Radia Bookshelf Loudspeakers Pair – Black
Compact Brilliance. Pure Radia Performance.
The Arcam Radia R25 Bookshelf Loudspeakers bring full-scale hi-fi sound into a refined, stand-mount design that suits modern living spaces. Designed to partner perfectly with Arcam’s Radia stereo and home cinema amplifiers, the R25 delivers detailed, room-filling performance without demanding floor space.
Whether positioned on dedicated stands or placed on a sturdy cabinet, these bookshelf speakers are built to offer a balanced, confident sound that feels natural at any listening level.
Designed for Detailed, Immersive Sound
At the heart of the R25 is a 25mm Deep Ceramic Composite (DCC) dome tweeter, housed within Arcam’s Acoustic Lens waveguide. This design helps control dispersion, delivering smooth, open high frequencies with impressive clarity. The result is a wide, convincing soundstage that remains consistent even when you’re not seated directly in the sweet spot.
Handling midrange and bass is a 165mm Micro Ceramic Composite (MCC) woofer, carefully engineered for speed, control and low distortion. Vocals sound clean and expressive, while instruments maintain texture and precision. Bass notes feel tight and rhythmic rather than overblown, making the R25 equally comfortable with acoustic recordings, rock, electronic or film soundtracks.
With a broad frequency response of 43Hz – 40kHz, the R25 reaches deeper and higher than you might expect from a compact bookshelf speaker, offering performance that rivals many slim floorstanders.
Optimised Cabinet & Crossover Engineering
The R25 cabinet has been developed with rigidity and resonance control in mind. Internal bracing reduces unwanted vibration, helping maintain clarity and focus across the frequency range. Precision-engineered driver frames improve airflow around the woofer, supporting cleaner, more agile bass response.
Inside, a carefully tuned 2-way crossover network uses quality components to ensure smooth integration between the tweeter and woofer. This seamless handover is key to the R25’s coherent presentation, where music flows naturally from low bass to sparkling treble.
Part of the Arcam Radia Family
The R25 is more than just a stereo bookshelf speaker. As part of the Radia loudspeaker range, it can be integrated into a complete home cinema setup with matching floorstanders, centre speaker and subwoofer. This allows you to build a system that looks consistent and delivers a unified, high-performance sound signature throughout the room.
For optimal synergy, pair the R25 with compatible Radia amplifiers such as the A5+, A15+ or A25+ for a system that’s dynamic, controlled and engaging.
Elegant Black Finish with Contemporary Detail
Finished in a premium Black Walnut veneer, the R25 blends classic craftsmanship with modern styling. Subtle design accents reflect the Radia aesthetic, while a magnetically attached grille keeps the front baffle clean and uncluttered. Hidden mounting and discreet fixings ensure the speakers look refined whether the grille is on or off.
