You would require a amp or receiver as those are passive speakers. But yes you can run your sound card to the amp/receiver.

Edit incase you were unaware also, seems those speakers are sold each, so thats $85 per speaker.

It looks like they are passive speakers, so you will need an amp to go with them. They also will not have amazing bass and probably sound empty in that area, so consider a sub in the future if you get this setup. Your sound card is sending a data signal which is very weak. When you have passive speakers, they take direct input from whatever is plugged into them and output that depending on their rated wattage. So if you hooked up the speakers to the sound card, you wouldn't hear anything since they are passive. The amplifier takes the signal outputted from your sound card and essentially makes it stronger it so that the signal is powerful enough to power the passive speakers.

The difference between passive and active speakers is that passive only have the drivers and crossover in them if they have multiple drivers. An active speaker has a small amplifier built into them, so you only need to plug in a signal, not an amplified one.

Also yes, they are $85 each.

I'm aware that they are sold Each. thumb.gif So even though my sound card has a built in amp it is only for headphones?

Most likely. Even if it was an actual amp, you wouldn't be able to turn your speaker up much at all. Headphone drivers are much smaller and require much less power to produce effective sound because of the short distance from your ear. For small amps, I would look at Parts Express. They produce some cheap amps that give you really clean sound for their price. There are three particular models by Dayton (parts express' personal brand) which are a a 15WPC amp, a 50WPC amp, and a 100 WPC amp that I would pay particular attention to.

EDIT: Also consider their speaker kits. They are really affordable and produce some great sound.
