Summary: Let me start off by saying that at this price range the speaker performance and amount of functions the system has makes it a great deal. And if your looking to have have DLP IIz set up it'll work just fine for you. However having said that this system is not designed for a traditional 7.1 set up! To start with only 2 of the 4 rear speakers are wireless. The surround back speakers are still wired, while the surround speakers are wireless.
