I've got two sets of these things, there are 4 surround sound and one center speaker. I had one set it broke sent it in under warranty they sent me a new set. that set was broken too! so i got a new set.
So the two subs that came with these 10 speakers dont work, but as you can see these are still in hte plastic.
The four speakers are rated at 62 watts RMS (not peak) and the center at 69RMS.
All you would need is a sub and a 5.1 reciver, these will work with any stereo...it doesnt have to be a surround sound system.
And if your wondering most recivers will work with computer sound cards, especially those with SPDIF connections.
