As I have stated in an earlier post I am the soon to be proud owner of a 25-31pc+. It should be here sometime next week. My question is about placement but not about placement??? I read many threads about these subwoofers shaking the walls and pictures rattling. The prime place for me to place the sub when it arrives has collectable art on both walls. While I doubt I will run it at close to reference level, should I sincerly be concerned about the art on the wall? They properly secured to the wall, but should one of them fall, there will be a wife factor of biblical proportions. Your always good recomendations are requested!!!!
