The weight can be a real challenge. Do you have anyone who can help you with those things? They are a two person job, and if you are taking them up or down some stairs, you will need a dolly of some kind. I would use a shoulder dolly along with a buddy who is in good shape. If you can't arrange that, get
this. The Monolith subs are brutally heavy. If the weight is a real logistical problem for you, consider getting similar spec'd subs from Hsu Research, SVS, or Outlaw Audio.
