Arcam Radia R25 Bookshelf Loudspeaker

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.
