Okay I know next to nothing about setting up a HT system. So what parts will I need to set up a system for my bedroom that I'll be able to connect to my PC as well as my TV and Game consoles. Also I plan to start small with a 2.1 system and am currently looking at purchasing a couple of Ascend CBM-170 SE but I don't know about the sub. What cables, etc. will I need?
