I have a subscription to that magazine; I look forward to reading the review.
I won't claim the SUB 2 is the "Best sub ever" but at the time the subwoofer was announced by Paradigm in the summer of 2009, they stated the design goal was to produce a better subwoofer than JL Audio's Gotham g213, but in a smaller package and at a lower price. Seems like a bargain to me.
I measured the smallest width of my SUB 2 to be ~19.75 inches, and it stands 24 inches high including the feet. I calculate the enclosure to be 4.7 cubic feet in volume using this formula
. If you haven't seen and heard this sub in person, you won't understand what an incredibly dense and powerful package it presents, compared to other subs of similar size.
