I now have my center speaker on top of my TV, hanging over about an inch to keep it from reflecting off the screen. To keep it from falling OFF my TV, I have it stuck on with blu-tac, something a lot of posters here seem to like. BUT I also read posts from people who talk about using mousepads or vibrapods to decouple their center speakers from the TV, to keep it from resonating...These seem like contradictory ideas to me. Doesn't blu-tac essentially couple the speaker to the TV? Which would mean I shouldn't be using blu-tac? Any opinions?
