While I'm more then satisfied with my single 20-39cs, I'd really like to go with 2 of them. I know it'll be killer for movies, I'm wondering about music. It took me awhile to get the single sounding good with music, but after I did, it's great. Currently listening to some Cypress Hill right now. (even though I'm a death/black metal fan) I'm really used to car audio type bass. I'm not really looking for that level of bass in my house or wherever I'm living at the time. So the question, does dual SVSs have a significant effect on music?
