5.1 pc setup for logitech z-640's

[Shuki]

I've just bought my very first set up 5.1 speakers. I've an audigy and have been using some philips 4.1 for the past year or so. Well I picked up a set of logitech z-640's and would like to set them up for the best performance. I've heard there was/is some sort of 5.1 Cd that like does all the different sounds on the different channels to help you adjust and setup specifically to individual tastes. Anyone heard of it? and where can I get one? preferably in a free DL of course :)

If your PC has a DVD drive you could just use an Avia (or similar home theater) set up disc.
