Jferreir,
As to isolation being a final tweak or a basic setup issue, it depends on your environment. It is not only speaker noise which matters. Buildings have resonance. Some of it is earthbound, some of it is how buildings react to outside elements. Some of it is how buildings turn noise in one place into vibration in other places. Part of it depends on where you live. If you live in the countryside on the eastern seaboard, far from roads, you may have little worry. If you live in a city, or in a region affected by earthquakes, you will find that buildings tend to resonate slightly most of the time. It is kind of creepy.
