That crate in the OP looks kinda familiar. I believe that the place I work with- who is an EV authorized repair center- at least once had a new 30W delivered- and it came in such a case, wrapped in cardboard, strapped to a pallet. The cloth may or may not be original.
BTW: I actually have rebuilt one of those 30Ws, from an organ, that had a bad voice coil. Fortunately, it's almost identical to the coil in one of the EV DL15/DL18 models, so I was able to use that coil- while saving the original styrofoam cone and surround- and make it work again.
If the cone and/or surround is damaged on one of those- you're basically SOL. But, as long as those are good- the speakers are fix-able.
