Moving into an apartment with wood joist floors - worried about neighbors hearing

The whole floor will act as a sounding board so it is necessary to damp the floor throughout much of the room, not just directly under the speaker.  Ideally you would get wall to wall carpeting with a very thick and dense pad.  If you can only manage area rugs, again, the thickest and densest rug covering as much as you can of the floor would help.  
 

The speakers should the be placed on vibration damping devices—specislty feet or s platform.  

Horn-based systems and dome other high efficiency systems tend to sound more lively when played at low volume.  Some also do a better job st focusing the sound energy at the listening position so that, they don’t have to played as loud.  Many of these systems don’t deliver very deep bass, and that is a plus in your setup.  An example of a good manufacturer of horn-based systems is Volti Audio.  High efficiency systems with great sounding speakers include the likes of Charney Audio and Songer Audio speakers.  Dipole speakers are also quite good in apartments because the front and back waves are out of phase and cancel at the sides; this becomes more pronounced as frequency drops so deep bass is attenuated the most.  The difference in sound that bleeds into other rooms between dipoles and othe types of speakers is substantial.  The dipole speakers I particularly like are the open baffle speakers made by Pure Audio Project.  They sound pretty at lower volume.

Loudness drops off quite a bit with increasing distance from the speaker; if you sit fairly close to the speaker it will sound louder.  Nearfield listening also reduces the impact of room acoustics on the sound.

I like the idea of using an equalizer, when necessary, to roll off bass.  You can use it during listening sessions during the evening, particularly at late hours, and use less or no equalization at other time, on weekends, etc.  It is a nice adaptive solution that will allow you to go wild on Saturday afternoons yet reduce noise transmission at other times.  In any case, rug and pad covering of the largest amount of floor possible will help a lot, as will any coverage of the walls with damping.  

The ultimate solution, one that will generally involve ownership of the space, involves companies that do isolation professionally--they can use springs and dampers to float a floor above the original floor, they can add additional noise damping sheetrock to existing walls (isolated from the existing wall by damping material such as "Green Glue" adhesive), and even treat the ceiling.

That looks like a very sensible, well thought out plan.  Bravo.  Now I can ask you:  how did you come up with your moniker?  I hope it is not because you really liked the Bruce Willis movie by that name.
