Well, on one hand, I think your AE15 idea would mate beautifully with the M1.7's.
On the other hand, a commercially available pre-built subwoofer would give you the opportunity to quickly try a sub out in the system and if it didn't meet your criteria/what-have-you, you could return it (and eat the restock fee and shipping).
I've heard the DWM panels, and while they mate well, they're huge and don't really give you true subwoofer punch and grunt.
Guess that's not much help, is it? LOL....
