Well here is my problem. I have an axiom vp150 center channel and i notice that when i play movies and a certain frequency happens which i found out with a tone generator is around 230hz makes the tv rattle. I have the center channel sitting on top of my tv which is a sony kp-43ht20. Does anyone have an idea how i can make the tv stop vibrating like what to put between the center and tv. I also cant take the center off the top of the tv and put it on a stand. The center has to stay on top of the tv. Thanks everyone for your time to read this.
