hey guys, i just started upgrading my HT system. i currently have a Harman Kardon AVR 225 reciever and i am planning on getting the partsexpress dayton sub unless someone can convince me otherwise. i will use it for almost 100% HT and not much if at any for music. i will have around $700 to spend on speakers which will include a center, 2 mains and 2 surrounds. if you guys can give me some suggestions on how to place this system together i would really appreciate it. thanks!
