People forget that when a speaker can start at let's say; 20hz, it only can reach this at a very high level of volume.
When you don't play loud, it will never reach 20hz even if a speaker is able to go this low.
When you use a subwoofer, it is possible to reach a much lower frequency at a lower volume level.
