Actually there is nothing wrong with running two subs with the same airspace, there are only to real problems when doing this. 1) The box will flex more causing unwanted noises possibly, to fix this brace the inside of the box very well. 2) If one subs goes out then the other will also if this is allowed to continue, the subs that is blown will move in and out with the other sub causing it to possibly over excursion and blow. Along with this it will sound like doo-doo, cuz of all the cancelation the blown sub will create.
