Arcam A25+ with R25 Bookshelf Speakers
It was way back in the mid-1970s when Doug Brady showcased the first amplifier from A&R Cambridge (as the company was then known) — the A60, which featured in many of our magazine adverts. The Arcam A25 continued that legacy with great success, earning a reputation for performance and reliability. Naturally, expectations are high for its successor, the Arcam A25+, which is set to carry the torch forward.

R25 Speakers
The ARCAM R25 brings the engineering excellence of the Radia Loudspeaker Series into a sleek, stand-mount design—perfect for modern living spaces where style and performance matter. Whether placed on a dedicated stand or a cabinet, the R25 delivers the full ARCAM experience in a form that fits effortlessly into your home.
Features
- 25mm (1-inch) DCC dome tweeter with Acoustic Lens and Waveguide for a detailed and effortlessly natural sound throughout your room
- Micro Ceramic Composite (MCC) woofer cone that is stiff and damped for distortion-free performance
- Inverted surround and trim ring cover both to conceal the hardware for a sleek aesthetic, and reduce damaging high frequency cabinet diffraction
- Newly patented cast frame engineered to optimize airflow for maximum cooling, reduced weight, increased rigidity, and improved performance
- Precision 2-Way Crossover featuring premium components to achieve seamless transducer integration
- Magnetically attached grille for a clean, seamless look with no visible attachments
At its heart is a 25mm (1-inch) Deep Ceramic Composite (DCC) dome tweeter, mounted in our advanced Acoustic Lens waveguide, ensuring smooth, natural highs and a wide, immersive soundstage—even when listening off-axis. Paired with a 165mm (6.5-inch) Micro Ceramic Composite (MCC) woofer, the R25 handles both midrange and bass with precision, producing rich, rhythmic sound that brings music to life and makes every beat feel effortless.
Like all other Radia Series speakers, the R25 features precision-engineered driver frames for optimal airflow and rigidity, and a hidden mounting system for a clean, elegant front panel. The cabinet, finished in premium Black Walnut veneer, combines timeless beauty with acoustic integrity, featuring rigid internal bracing for resonance free bass.
Inside, a carefully tuned 2-way crossover network uses premium components to preserve every nuance of your music. This design ensures seamless integration between the tweeter and woofer, creating a sound that feels open, dynamic, and deeply engaging—perfect for those who live for music with rhythm and energy.
The ARCAM R25 delivers the essence of Radia performance in a compact form—bringing you closer to the music you love
