Check your math again. Using the pi * radius squared formula for area, a 12" is equivalent to just under three 7" drivers.

I do agree with your comments about distance to wall and the overall effect of smaller woofers, no matter how many you have. My guess is that is a placement/listening position/room node issue. You tend to get nulls in the middle of the room. After having recently moved and fine tuned three systems for the best response, I have been recently reminded of the vast effect of both placement and room effects.
