ARCAM R25B
The ARCAM R25B is an active Radia subwoofer with a 250 mm coated fibre-composite driver and a 750-watt RMS Class D amplifier, rated at 1,500 watts peak. Its rear-ported enclosure is designed to extend the low-frequency foundation of a matching stereo or home cinema system.
RCA LFE/line-level inputs and a 12 V trigger support integration with an amplifier or processor. Level, crossover and phase controls help align the subwoofer with the main loudspeakers. The Black Walnut-veneered cabinet and magnetic grille coordinate with the Radia speaker range. ARCAM currently identifies this model as coming soon; availability must be confirmed before ordering.
