Sealed woofers used to be considered better for music, but is that still the case? When I read about subs, some reviewers make it seem like I am making a sacrifice by choosing one over the other. Since I listen mostly to classical and jazz, I am considering a sealed sub, but I have to believe that technology has progressed to the point that good ported subs can handle both music and HT equally well. I don't need supercharged HT sub output, just very good output? Thoughts? Any particular sub brands that would better suit my needs?
