Im pretty new to home theatre and plug along picking up pieces when I can. I currently have Klipsch kw100 sub Klipsch RC 52IV centre Energy cf50 tower speakers Marantz sr6009 receiver Theatre in a box surround sounds hooked up wirelessly I find the system very clear but I seem to have to keep my volume quite high, unless I have it in stereo when the energy speakers are by themselves. Also my sub lacks punch! I am about 10 feet away from the speakers. Is this normal or did I mix something up? S
