Stacks of prefab, preloaded boxes with fake port holes. And you have to mount the thing to seal the bottom, because it looks like there ain't no bottom. The top box in question has an inverted driver. The box material appears to be flimsy because it looks pretty thin. Stay away from these and save your money for something better.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
