Well here's how it goes. I just bought Attack of the Clones and watched it twice now. The first time I had full 6.1 going and it sounded pretty good. The sub worked alot and I didn't seem to get all that much for bass from my rf7's. So, thats when I decided to watch it again. This time I set my receiver to NO sub so all the bass was directed to my rf7's. OH MY GOD. Thats all I can say to describe it. These things can put out sooooo much bass its unreal. I didn't realize how much I was missing using the vtf2 as the main source of bass. Now I wonder if I actually do need a subwoofer. Is there a way to make the receiver send full bass to the mains and the sub? I had it set to large front speakers and sub on but that took bass away from the mains. No sub was an unbelievable experience. I just fell in love all over again with these speakers. They are absolutely amazing.
