I believe the reasoning behind multiple smaller drivers over one large driver is due to efficiency. The smaller drivers are easier to control and move than one large driver; this is why subwoofers have 500W or more for that one 12" or larger cone. Multiple smaller drivers work the same as one driver, in that you can add their sizes together and they achieve the same surface area of that one large driver thus achieving the same low frequency playback.
