Got a DIY question. My old Logitech Z-5500 took a dump on my PC and I want to go in a different direction. Just want a stereo setup with sub. I have a set of Edifier powered book shelf speakers R1280T which sound ok but lack on the bass (bass I used to hear on the Logitech sub, I can't hear anymore, I miss it). I am getting a Dayton Audio 10" sub. How do I hook both these up to my sound card on the PC?
