Which pair of 12s for mid sized ported box powered by SAZ1500D?

[mwoehr 1]

Hello everyone, I'm curious about 12s that could work great in a mid sized ported box 1.5 cubes - 1.75 cubes each powered by a Sundown SAZ1500D. So far what caught my eyes is a pair of DC Level 3 12s or a pair of Sundown SA 12s.
