Basically you are correct, if 2 subs are sharing the same airspace and one blows, now the
other sub has double the airspace, and it might be possible to damage that sub as well, and its going to sound like crud anyways. So a divided enclosure is usually a good idea, at least you will still have one sub, and the divider acts as a brace for the box as well to help limit the flexing of the box.
