Arcam Radia R25B Powered Subwoofer, Black

The Arcam R25B Subwoofer is designed to add powerful low-frequency depth and impact to Radia home cinema and hi-fi systems. Using a 10-inch coated fibre-composite driver in a cast aluminium frame, paired with a 750W RMS Class D amplifier, it delivers controlled bass with the headroom needed for demanding film soundtracks and music playback. The bass-reflex enclosure extends low-frequency performance down to 26Hz, helping create a fuller and more immersive listening experience.

Variable crossover, level, and phase controls allow the R25B to integrate smoothly with a wide range of speaker systems and room layouts. RCA LFE and line-level inputs provide compatibility with AV amplifiers and stereo systems, while the rear-mounted port helps maintain clean and controlled bass performance. Finished in Black Natural Walnut veneer with a magnetically attached grille and concealed driver hardware, the R25B is designed to visually complement the wider Radia speaker range while delivering substantial low-end performance.
