There are a few threads on this topic - you might search for them. Short answer(s):
1) the right subs will go deeper than 3.6s, may not matter much for music.
2) even if the bass from doesn't go deeper, it will sound different than the same frequencies from the 3.6s. Good thing or bad thing? YMMV.
3) the right sub/x-over can be successfully mated to Maggies, it may not be easy.
4) Don't get hung up on small drivers in the subs. IMHO they have little to do with getting a seamless "hand-off'.
5) Think about a room corrected sub. Bass is most affected by the room, RC/PEq will allow you to "fix" it without impacting the main signal path (other than a low-cut filter for the 3.6s).
Good Luck
