I'm looking to see which sub would be the best for me. Which ever one I get will be paired with the Polk Audio Monitor 30's or the Tsi100's. I'm leaning more on the Polk sub side because of the port being on the front because this sub will be backed up against a wall. (I do not see the port being blocked a good thing) I don't know a whole lot about sub setup and what not but any advice is appreciated. My room is pretty small too, about 15x15, so I don't need a whole lot of power, though the BIC would handle a lot more than the Polk. I listen to music more than I watch movies so which ever one is "better" for music would be the one I would get but, it still needs to be capable of producing good bass for movies.
