You can use the rear chamber to bring up response at the bottom end. Think about an underdamped sealed box, how it makes a peak at fb. That can be used to fill in a response dip at the low end. If the horn is large enough, you probably won't have much LF ripple but if you do, then reactance anulling from the rear chamber might be useful.
