I want to spend around $200 on some 2.1s and I am looking to get the most out of my money. They will be hooked up to my XBox. They can be computer speakers, a set of regular speakers or pieced together (maybe some bookshelf+sub). If I do end up getting computer speakers for this I have a RCA to anaglog adapter. Also, how should I position them in a small room with a flat ceiling? Thanks for the help.
