...The only real solution is an isolated room in which the floor is
detached
from the frame, and floated on springs and rubber doughnuts. This is very
effective, but also very expensive. It's pretty much the only way to get
good isolation in a commercial skyscraper, though.

And then you've created the additional problem of having a small room that
totally contains most of the low frequencies which means you are going to
lose a huge amount of floor space to trapping and other low frequency
absorption in order to make it sound as good as a normal, non-isolated room.

A location where you don't need to sweat low frequency isolation will ALWAYS
save you a fortune!
