I have a pair of Microlab 7C's connected to my home theater pc . They work like any other pc speaker . They do have a remote with an on/off switch and volume control too but you wont use it often .
The sound is excellent . Much better than any of the smaller pc speakers I have heard. For a start you get real bass . http://www.overclock3d.net/reviews/audio/microlab_solo_7c_review/1
