push-pull sub design question
I've got a question regarding push pull subwoofer design. Some push-pull designs have one driver facing outwards, one facing upwards mounted inverted. others have got both drivers facing in the same direction, one driver inverted. It is my understanding that the inverted driver is wired out of phase, so each driver moves out at the same time, and back in at the same time.
So what is the difference in this than having both drivers mounted facing in the same direction, neither of them inverted? (just a regular dual-driver sub) they're both traveling out and in at the same time, why is this not a push-pull design? is it the simple physical orientation of the inverted driver that makes it push-pull?
Help is appreciated all you experts out there!

Do a bit of reading about isobaric subwoofers. As long as they are moving the right direction, the main advantage to various driver orientations are going to be looks or physical geometry. An exposed motor structure has a tendency to be a little noisier than an exposed cone, but it's up to the owner to decide if that's enough of a problem for them not to have the pretty magnet sticking out.
