I have tentatively narrowed down my sub choices to the two listed in the title of the thread. My room is small ( 17 x 13) and my ratio of music and movies is about equal. I listen at anywhere from 5 to 10 db below reference for movies and lower for music. I am interested in other people's opinions on these choices. I know I will need to listen to both and will do so. I have heard from a number of sources that sealed subs are better for music than ported systems, but a lot of users of SVS also listen extensively to music with apparent good results. Any insights are appreciated.
