I have Harmon Kardon speakers with a subwoofer that I used on my old PC; it used a Soundblaster card. Can I use the system on the iMac? If so, how? Thanks for your replies.
did they connect via any sort of unique/proprietary connectors? if not, as long as they connect optically, usb, or via a headphone jack connector you should be just fine.
