ok so i was right that tuning above 35 hz is better for most music.. i do have some q's about boxes don't wanta do a tread so #1 what tuning is better for rock music like 40hz? #2 what is a "hidden chamber" ported box? #3 is port are the same most of the time or would 4x4 port work as good as say a 1.5 or 2' w x 13" port or would just the most port area win, meaning is wider and shorter better than taller and skinny (ports talking about ports)?
