afaik tapped horns do not couple like a front loaded horn. so there's nothing to be gained by stacking them a particular way

So should the mouth open near the floor, as to use the floor as a horn extension?

I would think that lining multiple cabinets up with the mouth close to the floor would give the best coupling taking full advantage of the 2PI space.

The PD 12sb30 has a good Xmax for a tapped horn (7mm) and according to hornresp will reach x-max at about 46Volts which is 265W at 8 ohms.
No one has mentioned that you will need a hi pass filter and it will probably be to be at least 40hz.

I use these drivers www.cheaplights.com/cart/page81.html (the first 12" on the page) they are Cheap, work great and are very similar to the Radian 2312s. I do not use a high pass. these cabs are rather great, allowing a hell of a sound that one man can set up. I Use two currently and may build two more, but my Servodrives want to get out and see action as well and i must divert the funds to repair a few of them.

would the eminence lab 12 work in this design?cheersryan
