Hey congrats on your new stuff... I hope you are as happy as I am with these speakers. I also have a serious rattle in my subwoofer. I thought it was just my walls so I moved it to the center of my room and it is deffinately my sub enclosure. So I think I will have to replace it. I wonder if that has anything to do with the lack of output. I can see the sub is moving a lot of air but I am getting almost no output. I have tried almost every spot in my room with no luck... Hopefully it is just a quick fix. Aside from that these are some of the best speakers I have heard.
