not much comparable difference...except 3.6 db in efficiency, Obsidian has stitched surround and the obvious $47.00 ea. in price.
based on facts, with each sub is it's optimum enclosure with all power and source material being the same, the Obsidian will in fact shat on the skar 10...and I would bet on the 12 for that matter.
