Dear Erictye: IMHO there is almost no-so big for " these speakers " but the other way around: too small.
The DD-15 could works very good with your Cremona's, I can't see any trouble about and when you have two subs in true stereo fashion you can place it almost " everywhere ": see my Agon virtual to see that the place/room position of mines is not " orthodox " one.
If I was you and due that are on " sale " I just go a head. DEven if you don't like it ( that I seriously doubt. ) you always can put on sale with almost no lose because everyone wants it.
Regards and enjoy the music,
R.
