Reply to Bass Note

This could be a dumb/noob question, but generally for deep/hard sub bass, what note is generally used in dirty dutch type music, like afrojack type sub bass in this song where it drops at 3:15:

Right now I'm using the F1 note and its working pretty well I believe, just want to make sure

EDIT: Also, anyone have any tips on how to make the sub bass so audible even without big speakers? Other than compression

Thanks for any help
