Warren,
Best to have a buddy help, but it can be done alone. Do the same thing as with Def1: if your ceiling is high enough, open the base end of the box, spread the flaps open and stand the whole box on that end, then lift and shimmy the box off. Remove the foam cuffs and carefully unwrap the protective film. Alternately you can stand the speaker box on end, cut the long side open and "walk" the speaker out of the open box. What you don't have to do it lay it down and lift the Def out of its box -- unless you want to.
The Def4 is slightly larger than v1.5 but you can reuse the foam cuffs, maybe add some folded paper of foam to tighten that fit, and box them for the trip back to Zu. You may need to fill in some spaces around the perimeter of the cartons to make up for the slightly more slender Def1.
