I have had my SB12+ since Christmas. I have been slowly dialing it in with REQW when I have time and I find that everytime I tweak it I hear more and more detail. I really use our HT mostly for music first, movies second. I think it is great for music. I keep hearing things in old cd's that I never knew were there with my old Infinity RS sub (early 90's vintage). I guess I never really new what good bass sounded like before. For movies, it is good and solid, but I would not call it gut wrenching. But then again, we do not listen to movies at reference levels. It starts to roll off in our room at about 23 hz or so. One of the added benefits that I am noticing with network HDTV on cable, is that some of the DD sound tracks have some pretty decent bass. Not heavy handed at all, kind of delicate and deep if that makes sense. I am amazed that some of the music I listen to has less bass, because of the controlled sound of this sub. I find that it can really stop quickly and not ring thru like my old sub does. Oh, and by the way, shipping was not too bad- $28. So you would only be out $56 if you decide you don't like it, since you have a 45 day audition period. Hope this helps.
