From KEF website:
The LS50W uses a power supply that automatically senses the input voltage from your power outlet and adjusts
accordingly. The LS50W will operate at 110VAC/60Hz or 220VAC/50Hz without any switching required by the user.
Of course, you will need to have the appropriate socket adapter for your power outlet.
