These connect through a device on a serial port transmitting audio signal via wi-fi. The traditional jack is on "the other" end of the system. I could not find anything on the Creative Labs website regaring linux setup, neither on the Internet. I haven't used them yet, even on Windows (found them at work). Any idea how to go about connecting these?
You can see the speakers here: http://www.tomshardware.com/reviews/new-generation-pc-5-1-speaker-systems,1526-4.html
EDIT: The question was based on a wrong assumption that these speakers connect through a serial port which makes it invalid but I am leaving it here for others, there is actually nothing complicated in connecting G550W
