My HT is finally set up and running. I have some CRAZY rattles when i watch movies though. Whats the best way to get rid of them? I notice my lights in the basement are really bad and so are the fixtures in the ceiling that the lights go into it. Its almost like the roof is caving in....thats what it sounds like with big bass explosions. Also my speakers which are mounted to the walls seem like there rattling a bit also....so whats my solution to fix all these things on the walls rattling? Any tips or ideas?
