Are the two bass drivers fed in phase or in anti-phase? By in phase, I mean the two drivers move towards one another, squeezing the air between them and pushing it out the sides.

In phase would be Bi-pole out of phase Di-pole..
Yes I know that, but I'm trying to work out how these 'baffleless' designs work and not suffer from wave cancellation.

"In the next iteration I placed the woofers facing each other, simply because they were easier to mount as previously the rear speaker required longe standoffs to clear the frame. In this configuration, BTW, I had to reverse the polarity on one of the woofers to keep them acoustically in phase:"

I'm not sure I'm any the wiser. Are both woofers wired in anti-phase, or just one? If just one then you'd expect almost complete cancelation to occur in the space between the two woofers?
EDIT - Thinking about it more, working in tandem probably does need one wired in anti-phase, so that the two drivers 'suck' and 'blow' in the same lateral direction and not against each other.
