Anyone know if the USA logitech Z-2300 are 240V compliant?

(for the guys who dont know what I am on about: In the US the voltage is 110v and in Europe its 240v so if a device says only 110v and you plug it into a European socket, it will just burn out the device. For it to be usable in Europe it needs to be 240V compliant - normally it would be on a label nexto the powercord 110-240V)
