It does seem however that the OP has a secondary issue in so far as the room itself is exacerbating the sub-sonic issues. Bass traps will not help as they are also tuned to the audio range and cannot deal with sub 10Hz (think how large such a bass trap would need to be)
I wonder if the issue is the floor acting as a resonator then mass loading the floor in the appropriate manner might break things up?
Failing that as others have suggested an isolation fence could be a good idea -- many suppliers make such a thing but again it will not deal with the sub-sonic problems ...
