Default Foster 12" Woofer Ripole sub: single dual driver unit or dual single driver units?

I have posted a while ago about Foster drivers I found in Sears Professional speakers. I was advised that the 12" woofers might work well in a Riople subwoofer and I'm tempted to go this way to complement my great-sounding but bass-shy KEF 303.

I don't have experience with the Ripole and am wondering if it would be better for me to build a single module with the two woofers in it or two modules with on woofer each.

I think one module would get me higher efficiency and thus higher max SPL, something I understand is not the Ripole's forte, so that would help.

OTOH, two modules would get me "stereo bass", which I have seen advocated many times by reputable people.

What would you advise?

Stereo bass is probably over rated, but multiple mono woofers are a decided advantage.

So are you saying that two mono Ripole modules might be a good solution? I guess it would widen the dispersion pattern toward the listening area.

Much of the content of Toole's book are in a pdf on the subject of woofers. It has been linked at least a couple times on this forum. A required read.
