How to unpack 150lbs+ towers


Is there any sort of standard technique for removing 150lbs+ tower speakers from the packaging base? With no handles ( other than the drivers :) ) to grab onto? I have Pioneer S-1EX.

This takes advanced planning, but the best method I have found is using my two teenage sons.
Lay them down on their sides on a bed and slide them out of the bottom of the box. Keep the boxes and packing materials for the future.
