DD-12 Vs. DD-15


I really don't know which one to get...Is it true that the DD-15 is not THX certified? I like the smaller 12" but am wondering if the 15 is a significant step up. Thoughts?

Don't worry about the THX certification it more licensing than anything. if you have a mid-large room and you are going to use this for movies.. go as big as you can afford or better yet get stereo subs which will help out with accoustics versus one big sub. Both Velo's are awesome.
I replaced my HGS-18II with the DD-15 and couldn't be any happier. The DD-15 has tighter bass, less distortion and digital room EQ. If your room is big, better go with the DD-15 or better yet, DD-18.
Music is first and foremost the most important...but I don't want it to choke up for movies.
