The Arcam R25B Subwoofer is designed to deliver powerful, precise low-frequency performance for both music lovers and home cinema enthusiasts. As part of the acclaimed Arcam Radia Series, the R25B has been engineered to partner perfectly with Radia amplifiers, streamers and loudspeakers, providing a seamless and immersive listening experience.
Built on decades of acoustic engineering expertise from Arcam, the R25B combines high-output amplification, a carefully designed driver system and a rigid cabinet to produce bass that is both powerful and controlled. Whether enhancing a high-end stereo system or adding cinematic impact to a surround sound setup, the Arcam R25B delivers deep bass that remains tight, accurate and musically engaging.
At the heart of the Arcam R25B Subwoofer is a precision-engineered 10-inch (250mm) coated fibre-composite woofer designed to move large volumes of air while maintaining speed and accuracy. The driver is powered by a robust 750-watt digital amplifier, providing the energy needed to deliver room-filling bass with excellent control across a wide frequency range.
The cabinet uses a bass-reflex design with a rear-mounted port that has been carefully tuned to maximise low-frequency extension without sacrificing detail. This design allows the R25B to deliver deep, dynamic bass for modern film soundtracks while still revealing the subtle low-frequency detail that enhances musical recordings.
The Arcam R25B powered subwoofer has been designed for easy integration into a wide variety of audio systems. Rear-mounted controls allow users to fine-tune level, crossover and phase settings, ensuring the subwoofer blends perfectly with existing speakers.
The R25B is particularly well suited to pairing with Arcam AVA35 and other Radia Series electronics, as well as Radia floorstanding and bookshelf loudspeakers. When correctly integrated, the subwoofer extends the system’s low-frequency response while maintaining the balance and musicality that Arcam systems are known for.
The Arcam R25B Subwoofer reflects the refined design philosophy of the Radia Series. The cabinet is finished in a luxurious Black Walnut wood veneer, giving the subwoofer an elegant appearance that complements modern hi-fi systems and home cinema rooms alike.
Attention to detail is evident throughout the construction. A magnetically attached grille provides a clean front panel with no visible fasteners, while hidden mounting hardware and integrated trim rings maintain a minimalist aesthetic. Solid aluminium feet with optional spikes and floor protectors ensure optimal stability and isolation on a variety of surfaces.
With its combination of a high-performance 10-inch driver, powerful digital amplification and carefully tuned cabinet, the Arcam R25B Subwoofer delivers bass that is both impactful and refined. The result is a subwoofer capable of reproducing the deepest notes in music while adding dramatic weight and scale to film soundtracks. Designed to work seamlessly with Arcam electronics and speakers, the R25B places you right at the centre of your listening experience.
