Technically speaking sealed and vented are supposed to have a little different sound. I have never sat down to really notice the difference. Vented boxes generally have to be larger than sealed boxes. So when it comes to space saving, I would run one or two subs sealed. That's just coming from me. I've dealt with subs in the past, and I don't care about being the loudest *** in the neighborhood, so I would just run the shallows, which is still going to sound great, and call it a day.
