I see Wayne has replied and he instructed as to how to use the EQ to ameliorate floor resonances. I am not sure that is the post you seek however.
What I did was First I sistered all the floor joists under the listening room. Then I purchased these sheets of high densisty acoustic foam. I stapled a sheet between each joist flush against the floor. Then I ran lateral stringers and mounted sheetrock on those. Every other joist I drilled a hole and pumped insulation into the cavity. It sounds like a lot of work but you only need to do it under one room.My room is 16x14 so it amounted to about 15 2x4" 4 sheets sheetrock, 15 furring strips and some insulation blown in. Total about 150$; very much worth it! Suddenly, there was bass.
