i currently have a labtec 2.1 system hooked up to my laptop. i would like to get some quality speakers, but i need a external usb sound card. i should be getting some money soon, so if i buy this sound card with these 2 eltax speakers and a decent subwoofer and my ****ty 2 labtec speakers. would that work ? i.e. can i get the speaker connectors to connect to the usb sound card?
