Good ones can go down to 20 to 40 Hz when they fit well.
Subwoofers
Built for 20 to 120 Hz. Rattles here often mean a loose part in the room or the box.
Questions people ask
Why can I not hear the lowest tones on my phone?
Phone speakers are tiny and cannot move enough air for deep bass. Try headphones to hear the difference.
Do earbuds need a good seal?
Yes. If the ear tips do not seal, most of the bass is lost. Try a different tip size.
Can a bass test damage speakers?
Not at normal volume. Very loud low tones can push small speakers too far, so increase the volume slowly.
Why does a tone rattle?
Rattling can come from the speaker, its case or objects nearby. Water or dust in a phone speaker can also crackle.
