I'm no acoustical or mechanical engineer, but my amateur view on this subject is:
1- The smaller the baffle, the better. Less flexing of unsupported wood, and the resulting resonance.
2- The lower the center of gravity of the cabinet, the better. Less "rocking" of the cabinet in response to the cone's movement.
3- For the same reason as #2, a short, deep cabinet is more stable than a tall, shallow one.
As for Golden Ratio, etc......at subwoofer frequencies, those issues don't matter.
