The walls are very solid (1920), and the wall studs have really aged over the years...like drilling into hardwood. Then there's the plaster. I have a curio cabinet with light glass shelves on the other side of the wall. There are some tiny glass figurines on the shelf. When I open the cabinet door you can hear them rattle. However, not until I jump to about 6" off the floor can I hear anything...and I'm no lightweight.
My new concern is that the TT plus dampening slab will be heavier than the Target shelf can handle which is 88 lbs.
