Focus your speaker money on front speakers and center channel. The rears are not used that often. basicly any bookshelf speaker will do. I recommend tower speakers As for the subwoofer, If you have the ability, BUILD YOUR OWN!! I'll even design and send you specs if you'd like. I built mine and tested it at a local audio shop where a friend works. Blew everything (Including every Bose sub) away except for a JBL HT series..
