Headphones usually have capabilities to provide better definition and imaging and the best piecefull solution.
My other solution would be to advice neighbors to appear next time knocking at your door with presence of police officer(s) only. Cops less-likely will open the case or even will care to arrive for minor neighbor troubles thus leaving your neighbor 'grouchy' and somewhat 'upset' and probably seeking some mental help. Had similar neighbor by myself always knocking at my door and complaining about my noisy kids playing in the middle of the day.
While you being PIA to your neighbors you can always place your speakers on cardboard boxes as Elizabeth suggested. I found Egg boxes work best and somewhat as good as dedicated speaker stands.
