IME (reasonably extensive) sub-matching is a two step process, neither of which involve the "speed" of small drivers. The first step is matching the sub to the room - optimized with proper output capability, careful placement, multiple subs and /or parametric EQ. The second step is matching to the speaker. This involves finding the right crossover point and VERY careful level matching.
IMHO, the "speed" issue is more a function of the sub's damping than driver size and can best be represented by the "group delay" spec. Usually (but not always) sealed subs exhibit the lowest group delay and provide the fast (or maybe more acurately, "tight") bass that mates best with certain speakers.
SVS, and Rythmik (my choice) among others offer variable damping with makes matching easier. I also use a parametric EQ unit (Velodyne SMS-1) to smooth response and optimize the "handoff" from speaker to sub. The Maggies I use (SMG) presented some challenges, but - in the end -I got the precise result I was seeking.
Good Luck
