Is it just LOUD? or as usual, the bass vibrations are the real problem?
Well solid mass, or structural stiffening is the best bet to stop bass travelling.
Finding a place to cut a resonance is also a way.
My first suggestion is to get one or two of those braces used to shore up structural defects, a steel tube, with a screw and plates on the ends.. Try them around the perimeter of the room, away from the side walls of the house, and more towards the middle of the whole house in relation to the room below. They might even work outside the room! Crank them up against the floor. see if it helps.. Having one or two of those in the corners would be way easier than a LOT of other bass stopping tricks.
Anyway, that is my suggestion. Stop the floor from resonating.. If you find the right spot, maybe you can create some estetically pleasing cover for the floor jacks.
Another more drastic and expensive solutions is the cover the first level flooring with stone.. At least part of it.
A thirdd is to use speakers with way less bass.. And just accept it is what you have to do.
If you have a pair of subs and are cranking them up, nothing will stop the problem.
