You should read this article on subwoofer myths before proceeding. There are many discussions on many audio forums discussing the "musicality" of subwoofers especially those of a smaller driver being "faster" and "tighter" and larger drivers being more "sloppy" and "flabby". This article will explain many of these misconceptions.

The sections titled #3 Subwoofers are fast / slow, #4 Ported boxes don’t sound as good as sealed, #5 Subwoofers care what they play, #8 Smaller drivers sound better than bigger drivers you might find very informative.
