As good as dual ULS-15's would be for music, you owe it to yourself to try Audyssey (Ideally for the low frequencies only, using the app) just to make sure you are not leaving too much on the table by bypassing additional EQ! I like that Hsu offers the tuning flexibility that they do on these subs, I am sure you have realized what a loss it would be if your only option was one of the settings that did not work well with your setup!
