As Skibum mentions, this is a computer speaker system. It would be difficult to adapt this to home theater. The reason is that the inputs assume that the audio is already separated into the discrete channels. Look at the picture from the badck of the sub box and note that there are different stereo mini-din jacks for front, rear and center.
Trying to use these with a HT setup would require a DVD player or other device that already provided line level decoded output. There is also no switching. Exception. You could feed this from a media edition computer and get HDMI, component or composite input cards for it.
Sorry. I've thought about this as well, as the prices are usually really good.
