WattmeterAnother audio and computer equipment. This time let's take a look on old computer speakers that are used by my dad. They are branded as X-Techologies model XT-200, but I'd rather call it no name. ;-)
It's an old technology, so I wasn't surprised that there's almost no difference for them between power on and power off state. They use 2.5W when off, and turning them on changes power draw to 2.7W.
