Sounds like you are committed to selling so I won't try to talk you down from the cliff, but I am curious (since I own a pair of Duos of slightly later vintage and after a lot of fiddling with placement, settings and associated equipment, really love them). In my experience, I don't listen at ear shattering levels (although of course the Duos can play loud). Their virtue is their ability to handle the dynamics with so-called 'jump factor.' What is often 'penetrating' to neighbors in an apartment or shared wall situation is the bass. And just wondering, what you will replace them with, since, accepting my assumptions above, you may have the same issue with virtually any speaker, except perhaps for a mini monitor, old Quads, etc.
