Combine R1 with our optional BackPack II and you will be able to enjoy R1 wherever mains power is not available from the bathroom to the great outdoors. Placing batteries inside takes valuable speaker capacity, but BackPack II allows R1 to retain its rich mains powered performance with the benefit of complete portability.
A total evolution of the original, BackPack II attaches seamlessly to R1 and once fitted can be left permanently in place as it charges automatically whenever connected to a mains power supply. A full charge will provide up to twelve hours of mains free listening depending on volume.
BackPack II is also compatible with our MR1 Bluetooth Speaker System.
