Frequency Response of subs?

[CarAudioNewbie9 10+ year member]

How important is the frequency response of subwoofers? For example, what would be the difference between a 20-250 vs a 30-150? I know that anything above 100 is midbass and you don't want your subs producing midbass. So I guess the difference is between 20 and 30. 20 is lower, deeper, duh, but do songs go that low?

Some rap songs will play below 30hz but most are in the 35-50hz range. I think the box dictates a lot of how deep a sub will get.

the lower fs subs are able to play lower, impedance rises at fs. Not saying high fs subs cant play low. doubt you'll hear much 30hz from songs. I would say majority of songs range from 35hz-60hz .
