Hi, I understand that the Amplifier in the Z5500 is supposed to be 500W, but the sattalites are only 12w RMS really and sub maybe 70w RMS?. Anyway, on Friday there is a big generator coming as there the whole village is gonna be withought power for the whole day, so my mum complained and got the electric board to send out a generator for out house, anyway, its supposed to be able to run a whole house off it seen as its a propor massive thing, but I dont want my PC and Speakers to use much electric and I am expecting to use them with the generator, so anyone have any Idea how much electric the Logitech Z5500 speakers will use playing at a nice volume, I would say up to 10bars on the control pod which for me is a nice decent volume with bass that goes nicely with it (sub on 4+), so you think the Z5500 will consume loads of electric?
