I just ordered a pair of m22ti, qs8, and a vp150. I already have an Athena 8" sub. I just moved into my new apt Sat. so the fun will begin shortly....

What I found to be very helpful (and what I did at previous places, and what I will do at my new apt I just moved into) is go talk to your neighbors. Tell them you had the home theatre setup in your previous apt with no complaints, but you just wanted to let them know and tell them they can come tell you anytime it gets too loud. I only had one person ever come up to me in my old apartment, and he stayed to watch the rest of the Fifth Element with us =)

Just be honest and friendly...I think that will go alot further than sound dampening.
