Can My Subwoofers Damage My Home

Hi, I have 2 Paradigm Signature Sub 25s in my second Floor Home Theater and they vibrate my room when i watch movies. I wonder if this causes any structural damage to my Home . Each sub is sitting on top of 2 Auralex Grammas and i beleive the virations are coming from the sound rather than the physical vibration of the Subs itself. Do you think this will cause any structural damage to my House?
