How do subwoofers produce such extreme bass?

Big speakers make louder sounds!
You just don’t have big speakers for higher pitches because bigger speakers are terrible at playing back high pitches.
As for why:
A typical speaker is a cone shape and is driven from the center from a coil.
To visualize why this doesn’t work so well think about wiggling a fishing pole. If you wave it back and forth slowly it stays pretty straight. If you wave it a bit more quickly it gets floppy. If you wave it real fast you just get it bending back and forth in place.
The fact that a speaker is round instead of a stick, and shaped like a cone helps prevent that to a point, but the same principle applies. A big speaker works fine at low frequencies, but at high frequencies the shape of the cone just kind of deforms.
