Help! Subwoofer causing granite to crack
My husband has his home theatre set up in a room in the basement. Directly above this room is our kitchen that has granite floors probably set in a concrete bed. I noticed a thin hairline fracture in the granite running from one side of the kitchen to the other. And now there is another new fracture. I suspect the loud vibrations from the home theatre sound system is causing the kitchen floor above it to move thereby causing the fractures. Could anyone suggest what to do to stop the sound/vibrations from travelling upwards to the kitchen floor? Currently, we have the subwoofer on the lowest setting as a temporary solution, but we are losing out on the full theatre experience. Thanks in advance for your suggestions!
